-# How to contribute
-
-## Things we will merge
-
-* Bugfixes
-* Performance improvements
-* Features that are likely to be useful to the majority of Liquid users
-* Documentation updates that are concise and likely to be useful to the majority of Liquid users
-
-## Things we won't merge
-
-* Code that introduces considerable performance degrations
-* Code that touches performance-critical parts of Liquid and comes without benchmarks
-* Features that are not important for most people (we want to keep the core Liquid code small and tidy)
-* Features that can easily be implemented on top of Liquid (for example as a custom filter or custom filesystem)
-* Code that does not include tests
-* Code that breaks existing tests
-* Documentation changes that are verbose, incorrect or not important to most people (we want to keep it simple and easy to understand)
-
-## Workflow
-
-* [Sign the CLA](https://cla.shopify.com/) if you haven't already
-* Fork the Liquid repository
-* Create a new branch in your fork
-  * For updating [Liquid documentation](https://shopify.github.io/liquid/), create it from `gh-pages` branch. (You can skip tests.)
-* If it makes sense, add tests for your code and/or run a performance benchmark
-* Make sure all tests pass (`bundle exec rake`)
-* Create a pull request

-# Liquid template engine
+To run, follow these steps:
 
-* [Contributing guidelines](CONTRIBUTING.md)
-* [Version history](History.md)
-* [Liquid documentation from Shopify](https://shopify.dev/docs/api/liquid)
-* [Liquid Wiki at GitHub](https://github.com/Shopify/liquid/wiki)
-* [Website](http://liquidmarkup.org/)
-
-## Introduction
-
-Liquid is a template engine which was written with very specific requirements:
-
-* It has to have beautiful and simple markup. Template engines which don't produce good looking markup are no fun to use.
-* It needs to be non evaling and secure. Liquid templates are made so that users can edit them. You don't want to run code on your server which your users wrote.
-* It has to be stateless. Compile and render steps have to be separate so that the expensive parsing and compiling can be done once and later on you can just render it passing in a hash with local variables and objects.
-
-## Why you should use Liquid
-
-* You want to allow your users to edit the appearance of your application but don't want them to run **insecure code on your server**.
-* You want to render templates directly from the database.
-* You like smarty (PHP) style template engines.
-* You need a template engine which does HTML just as well as emails.
-* You don't like the markup of your current templating engine.
-
-## What does it look like?
-
-```html
-<ul id="products">
-  {% for product in products %}
-    <li>
-      <h2>{{ product.name }}</h2>
-      Only {{ product.price | price }}
-
-      {{ product.description | prettyprint | paragraph }}
-    </li>
-  {% endfor %}
-</ul>
-```
-
-## How to use Liquid
-
-Install Liquid by adding `gem 'liquid'` to your gemfile.
-
-Liquid supports a very simple API based around the Liquid::Template class.
-For standard use you can just pass it the content of a file and call render with a parameters hash.
-
-```ruby
-@template = Liquid::Template.parse("hi {{name}}") # Parses and compiles the template
-@template.render('name' => 'tobi')                # => "hi tobi"
-```
-
-### Concept of Environments
-
-In Liquid, a "Environment" is a scoped environment that encapsulates custom tags, filters, and other configurations. This allows you to define and isolate different sets of functionality for different contexts, avoiding global overrides that can lead to conflicts and unexpected behavior.
-
-By using environments, you can:
-
-1. **Encapsulate Logic**: Keep the logic for different parts of your application separate.
-2. **Avoid Conflicts**: Prevent custom tags and filters from clashing with each other.
-3. **Improve Maintainability**: Make it easier to manage and understand the scope of customizations.
-4. **Enhance Security**: Limit the availability of certain tags and filters to specific contexts.
-
-We encourage the use of Environments over globally overriding things because it promotes better software design principles such as modularity, encapsulation, and separation of concerns.
-
-Here's an example of how you can define and use Environments in Liquid:
-
-```ruby
-user_environment = Liquid::Environment.build do |environment|
-  environment.register_tag("renderobj", RenderObjTag)
-end
-
-Liquid::Template.parse(<<~LIQUID, environment: user_environment)
-  {% renderobj src: "path/to/model.obj" %}
-LIQUID
-```
-
-In this example, `RenderObjTag` is a custom tag that is only available within the `user_environment`.
-
-Similarly, you can define another environment for a different context, such as email templates:
-
-```ruby
-email_environment = Liquid::Environment.build do |environment|
-  environment.register_tag("unsubscribe_footer", UnsubscribeFooter)
-end
-
-Liquid::Template.parse(<<~LIQUID, environment: email_environment)
-  {% unsubscribe_footer %}
-LIQUID
-```
-
-By using Environments, you ensure that custom tags and filters are only available in the contexts where they are needed, making your Liquid templates more robust and easier to manage.
-
-### Error Modes
-
-Setting the error mode of Liquid lets you specify how strictly you want your templates to be interpreted.
-Normally the parser is very lax and will accept almost anything without error. Unfortunately this can make
-it very hard to debug and can lead to unexpected behaviour.
-
-Liquid also comes with a stricter parser that can be used when editing templates to give better error messages
-when templates are invalid. You can enable this new parser like this:
-
-```ruby
-Liquid::Environment.default.error_mode = :strict
-Liquid::Environment.default.error_mode = :strict # Raises a SyntaxError when invalid syntax is used
-Liquid::Environment.default.error_mode = :warn # Adds strict errors to template.errors but continues as normal
-Liquid::Environment.default.error_mode = :lax # The default mode, accepts almost anything.
-```
-
-If you want to set the error mode only on specific templates you can pass `:error_mode` as an option to `parse`:
-```ruby
-Liquid::Template.parse(source, error_mode: :strict)
-```
-This is useful for doing things like enabling strict mode only in the theme editor.
-
-It is recommended that you enable `:strict` or `:warn` mode on new apps to stop invalid templates from being created.
-It is also recommended that you use it in the template editors of existing apps to give editors better error messages.
-
-### Undefined variables and filters
-
-By default, the renderer doesn't raise or in any other way notify you if some variables or filters are missing, i.e. not passed to the `render` method.
-You can improve this situation by passing `strict_variables: true` and/or `strict_filters: true` options to the `render` method.
-When one of these options is set to true, all errors about undefined variables and undefined filters will be stored in `errors` array of a `Liquid::Template` instance.
-Here are some examples:
-
-```ruby
-template = Liquid::Template.parse("{{x}} {{y}} {{z.a}} {{z.b}}")
-template.render({ 'x' => 1, 'z' => { 'a' => 2 } }, { strict_variables: true })
-#=> '1  2 ' # when a variable is undefined, it's rendered as nil
-template.errors
-#=> [#<Liquid::UndefinedVariable: Liquid error: undefined variable y>, #<Liquid::UndefinedVariable: Liquid error: undefined variable b>]
-```
-
-```ruby
-template = Liquid::Template.parse("{{x | filter1 | upcase}}")
-template.render({ 'x' => 'foo' }, { strict_filters: true })
-#=> '' # when at least one filter in the filter chain is undefined, a whole expression is rendered as nil
-template.errors
-#=> [#<Liquid::UndefinedFilter: Liquid error: undefined filter filter1>]
-```
-
-If you want to raise on a first exception instead of pushing all of them in `errors`, you can use `render!` method:
-
-```ruby
-template = Liquid::Template.parse("{{x}} {{y}}")
-template.render!({ 'x' => 1}, { strict_variables: true })
-#=> Liquid::UndefinedVariable: Liquid error: undefined variable y
-```
-
-### Usage tracking
-
-To help track usages of a feature or code path in production, we have released opt-in usage tracking. To enable this, we provide an empty `Liquid:: Usage.increment` method which you can customize to your needs. The feature is well suited to https://github.com/Shopify/statsd-instrument. However, the choice of implementation is up to you.
-
-Once you have enabled usage tracking, we recommend reporting any events through Github Issues that your system may be logging. It is highly likely this event has been added to consider deprecating or improving code specific to this event, so please raise any concerns.

+title: Introduction
+description: An overview of objects, tags, and filters in the Liquid template language.
+redirect_from: /basics/
+---
+
+Liquid uses a combination of [**objects**](#objects), [**tags**](#tags), and [**filters**](#filters) inside **template files** to display dynamic content.
+
+## Objects
+
+**Objects** contain the content that Liquid displays on a page. Objects and variables are displayed when enclosed in double curly braces: `{% raw %}{{{% endraw %}` and `{% raw %}}}{% endraw %}`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ page.title }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ page.title }}
+```
+
+In this case, Liquid is rendering the content of the `title` property of the `page` object, which contains the text `{{ page.title }}`.
+
+## Tags
+
+**Tags** create the logic and control flow for templates. The curly brace percentage delimiters `{% raw %}{%{% endraw %}` and `{% raw %}%}{% endraw %}` and the text that they surround do not produce any visible output when the template is rendered. This lets you assign variables and create conditions or loops without showing any of the Liquid logic on the page.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% if user %}
+  Hello {{ user.name }}!
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+  Hello Adam!
+```
+
+Tags can be categorized into various types:
+
+- [Control flow]({{ "/tags/control-flow/" | prepend: site.baseurl }})
+- [Iteration]({{ "/tags/iteration/" | prepend: site.baseurl }})
+- [Template]({{ "/tags/template/" | prepend: site.baseurl }})
+- [Variable assignment]({{ "/tags/variable/" | prepend: site.baseurl }})
+
+You can read more about each type of tag in their respective sections.
+
+## Filters
+
+**Filters** change the output of a Liquid object or variable. They are used within double curly braces `{% raw %}{{ }}{% endraw %}` and [variable assignment]({{ "/tags/variable/" | prepend: site.baseurl }}), and are separated by a pipe character `|`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ "/my/fancy/url" | append: ".html" }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ "/my/fancy/url" | append: ".html" }}
+```
+
+Multiple filters can be used on one output, and are applied from left to right.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ "adam!" | capitalize | prepend: "Hello " }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ "adam!" | capitalize | prepend: "Hello " }}
+```

+title: Operators
+description: Using operators to perform calculations in the Liquid template language.
+---
+
+Liquid includes many logical and comparison operators. You can use operators to create logic with [control flow]({{ "/tags/control-flow/" | prepend: site.baseurl }}) tags.
+
+## Basic operators
+
+<table>
+  <tbody>
+    <tr>
+      <td><code>==</code></td>
+      <td>equals</td>
+    </tr>
+    <tr>
+      <td><code>!=</code></td>
+      <td>does not equal</td>
+    </tr>
+    <tr>
+      <td><code>&gt;</code></td>
+      <td>greater than</td>
+    </tr>
+    <tr>
+      <td><code>&lt;</code></td>
+      <td>less than</td>
+    </tr>
+    <tr>
+      <td><code>&gt;=</code></td>
+      <td>greater than or equal to</td>
+    </tr>
+    <tr>
+      <td><code>&lt;=</code></td>
+      <td>less than or equal to</td>
+    </tr>
+    <tr>
+      <td><code>or</code></td>
+      <td>logical or</td>
+    </tr>
+    <tr>
+      <td><code>and</code></td>
+      <td>logical and</td>
+    </tr>
+  </tbody>
+</table>
+
+For example:
+
+```liquid
+{%- raw -%}
+{% if product.title == "Awesome Shoes" %}
+  These shoes are awesome!
+{% endif %}
+{% endraw %}
+```
+
+You can do multiple comparisons in a tag using the `and` and `or` operators:
+
+```liquid
+{%- raw -%}
+{% if product.type == "Shirt" or product.type == "Shoes" %}
+  This is a shirt or a pair of shoes.
+{% endif %}
+{% endraw %}
+```
+
+## contains
+
+`contains` checks for the presence of a substring inside a string.
+
+```liquid
+{%- raw -%}
+{% if product.title contains "Pack" %}
+  This product's title contains the word Pack.
+{% endif %}
+{% endraw %}
+```
+
+`contains` can also check for the presence of a string in an array of strings.
+
+```liquid
+{%- raw -%}
+{% if product.tags contains "Hello" %}
+  This product has been tagged with "Hello".
+{% endif %}
+{% endraw %}
+```
+
+`contains` can only search strings. You cannot use it to check for an object in an array of objects.
+
+## Order of operations
+
+In tags with more than one `and` or `or` operator, operators are checked in order *from right to left*. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.
+
+```liquid
+{%- raw -%}
+{% if true or false and false %}
+  This evaluates to true, since the `and` condition is checked first.
+{% endif %}
+{% endraw %}
+```
+
+```liquid
+{%- raw -%}
+{% if true and false and false or true %}
+  This evaluates to false, since the tags are checked like this:
+
+  true and (false and (false or true))
+  true and (false and true)
+  true and false
+  false
+{% endif %}
+{% endraw %}
+```

+title: Truthy and falsy
+description: An overview of boolean logic in the Liquid template language.
+---
+
+When a non-boolean [data type]({{ "/basics/types/" | prepend: site.baseurl }}) is used in a boolean context (such as a conditional tag), Liquid decides whether to evaluate it as `true` or `false`. Data types that return `true` by default are called **truthy**. Data types that return false by default are called **falsy**.
+
+## Truthy
+
+All values in Liquid are truthy except `nil` and `false`.
+
+In the example below, the text "Tobi" is not a boolean, but it is truthy in a conditional:
+
+```liquid
+{%- raw -%}
+{% assign name = "Tobi" %}
+
+{% if name %}
+  This text will always appear since "name" is defined.
+{% endif %}
+{% endraw %}
+```
+
+[Strings]({{ "/basics/types/#string" | prepend: site.baseurl }}), even when empty, are truthy. The example below will create empty HTML tags if `page.category` exists but is empty:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% if page.category %}
+  <h1>{{ page.category }}</h1>
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```html
+  <h1></h1>
+```
+
+## Falsy
+
+The only values that are falsy in Liquid are [`nil`]({{ "/basics/types/#nil" | prepend: site.baseurl }}) and [`false`]({{ "/basics/types/#boolean" | prepend: site.baseurl }}).
+
+## Summary
+
+The table below summarizes what is truthy or falsy in Liquid.
+
+|               | truthy        | falsy         |
+| ------------- |:-------------:|:-------------:|
+| true          | •             |               |

+title: Types
+description: An overview of data types in the Liquid template language.
+---
+
+Liquid objects can be one of six types:
+
+- [String](#string)
+- [Number](#number)
+- [Boolean](#boolean)
+- [Nil](#nil)
+- [Array](#array)
+- [EmptyDrop](#emptydrop)
+
+You can initialize Liquid variables using [`assign`]({{ "/tags/variable/#assign" | prepend: site.baseurl }}) or [`capture`]({{ "/tags/variable/#capture" | prepend: site.baseurl }}) tags.
+
+## String
+
+Strings are sequences of characters wrapped in single or double quotes:
+
+```liquid
+{%- raw -%}
+{% assign my_string = "Hello World!" %}
+{% endraw %}
+```
+
+Liquid does not convert escape sequences into special characters.
+
+## Number
+
+Numbers include floats and integers:
+
+```liquid
+{%- raw -%}
+{% assign my_int = 25 %}
+{% assign my_float = -39.756 %}
+{% endraw %}
+```
+
+## Boolean
+
+Booleans are either `true` or `false`. No quotations are necessary when declaring a boolean:
+
+```liquid
+{%- raw -%}
+{% assign foo = true %}
+{% assign bar = false %}
+{% endraw %}
+```
+
+## Nil
+
+Nil is a special empty value that is returned when Liquid code has no results. It is **not** a string with the characters "nil".
+
+Nil is [treated as false]({{ "/basics/truthy-and-falsy/#falsy" | prepend: site.baseurl }}) in the conditions of `if` blocks and other Liquid tags that check the truthfulness of a statement.
+
+In the following example, if the user does not exist (that is, `user` returns `nil`), Liquid will not print the greeting:
+
+```liquid
+{%- raw -%}
+{% if user %}
+  Hello {{ user.name }}!
+{% endif %}
+{% endraw %}
+```
+
+Tags or outputs that return `nil` will not print anything to the page.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+The current user is {{ user.name }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+The current user is
+```
+
+## Array
+
+Arrays hold lists of variables of any type.
+
+### Accessing items in arrays
+
+To access all the items in an array, you can loop through each item in the array using an [iteration tag]({{ "/tags/iteration/" | prepend: site.baseurl }}).
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
+{% for user in site.users %}
+  {{ user }}
+{% endfor %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+  Tobi Laura Tetsuro Adam
+```
+
+### Accessing specific items in arrays
+
+You can use square bracket `[` `]` notation to access a specific item in an array. Array indexing starts at zero. A negative index will count from the end of the array.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
+{{ site.users[0] }}
+{{ site.users[1] }}
+{{ site.users[-1] }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+Tobi
+Laura
+Adam
+```
+
+### Initializing arrays
+
+You cannot initialize arrays using only Liquid.
+
+You can, however, use the [`split`]({{ "/filters/split/" | prepend: site.baseurl }}) filter to break a string into an array of substrings.
+
+## EmptyDrop
+
+An EmptyDrop object is returned if you try to access a deleted object. In the example below, `page_1`, `page_2` and `page_3` are all EmptyDrop objects:
+
+```liquid
+{%- raw -%}
+{% assign variable = "hello" %}
+{% assign page_1 = pages[variable] %}
+{% assign page_2 = pages["does-not-exist"] %}
+{% assign page_3 = pages.this-handle-does-not-exist %}
+{% endraw %}
+```
+
+### Checking for emptiness
+
+You can check to see if an object exists or not before you access any of its attributes.
+
+```liquid
+{%- raw -%}
+{% unless pages == empty %}
+  <h1>{{ pages.frontpage.title }}</h1>
+  <div>{{ pages.frontpage.content }}</div>
+{% endunless %}
+{% endraw %}
+```
+
+Both empty strings and empty arrays will return `true` if checked for equivalence with `empty`.

+title: Variations of Liquid
+description: An overview of the different installations of Liquid and how Liquid can change depending on where you're using it.
+---
+
+Liquid is a flexible, safe language, and is used in many different environments. Liquid was created for use in [Shopify](https://www.shopify.com) stores, and is also used extensively on [Jekyll](https://jekyllrb.com) websites. Over time, both Shopify and Jekyll have added their own objects, tags, and filters to Liquid. The most popular versions of Liquid that exist are **Liquid**, **Shopify Liquid for themes**, and **Jekyll Liquid**.
+
+This site documents the latest version of **Liquid** including betas and release candidates — that is, Liquid as it exists outside of Shopify and Jekyll. If you download the Liquid repository or install it as a [gem](https://rubygems.org/gems/liquid), you will get access to whatever objects, tags, and filters are in the version of Liquid that you chose.
+
+## Shopify
+
+Shopify always uses the latest version of Liquid as a base, but Shopify adds a significant number of objects, tags, and filters to Liquid for use in merchants' stores. These include objects representing store, product, and customer information, and filters for displaying store data and manipulating storefront assets like product images.
+
+Shopify has several versions of Liquid. The most popular version is used to build Shopify themes. To learn about the Liquid elements that you can use to build Shopify themes, and to learn about the other versions of Liquid at Shopify, refer to the [Shopify Liquid reference](https://shopify.dev/api/liquid).
+
+## Jekyll
+
+[Jekyll](https://jekyllrb.com) is a static site generator, a command-line tool that creates websites by merging templates with content files. Jekyll uses Liquid as its template language, and adds a few objects, tags, and filters. These include objects representing content pages, tags for including snippets of content in others, and filters for manipulating strings and URLs.
+
+Jekyll also powers [GitHub Pages](https://pages.github.com/), a web hosting service that lets you push a Jekyll installation to a GitHub repository and have the resulting website published. This website is built using GitHub Pages.
+
+Jekyll might not be using the latest version of Liquid. This means that the tags and filters listed on this site may not work in Jekyll. Often the Jekyll project will wait for a stable release of Liquid rather than using a beta or release candidate version. To see which version of Liquid is being used by Jekyll or GitHub Pages, check the **runtime dependencies** section of the gem page for [Jekyll](https://rubygems.org/gems/jekyll) or [GitHub Pages](https://rubygems.org/gems/github-pages).
+
+Jekyll's version of Liquid is documented in the [Liquid section of Jekyll's documentation](https://jekyllrb.com/docs/liquid/). If you want to try out Jekyll's version of Liquid, you can clone the Jekyll project or install Jekyll as a gem and test Liquid on a static site.

+title: Whitespace control
+description: An overview of controlling whitespace between code in the Liquid template language.
+---
+
+In Liquid, you can include a hyphen in your tag syntax `{% raw %}{{-{% endraw %}`, `{% raw %}-}}{% endraw %}`, `{% raw %}{%-{% endraw %}`, and `{% raw %}-%}{% endraw %}` to strip whitespace from the left or right side of a rendered tag.
+
+Normally, even if it doesn't print text, any line of Liquid in your template will still print a blank line in your rendered HTML:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_variable = "tomato" %}
+{{ my_variable }}
+{% endraw %}
+```
+
+Notice the blank line before "tomato" in the rendered template:
+
+<p class="code-label">Output</p>
+```text
+{% assign my_variable = "tomato" %}
+{{ my_variable }}
+```
+
+By including a hyphen in your `assign` closing delimiter, you can strip the whitespace following it from the rendered template:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_variable = "tomato" -%}
+{{ my_variable }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% assign my_variable = "tomato" -%}
+{{ my_variable }}
+```
+
+If you don't want any of your tags to print whitespace, as a general rule you can add hyphens to both sides of all your tags (`{% raw %}{%-{% endraw %}` and `{% raw %}-%}{% endraw %}`):
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign username = "John G. Chalmers-Smith" %}
+{% if username and username.size > 10 %}
+  Wow, {{ username }} , you have a long name!
+{% else %}
+  Hello there!
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output without whitespace control</p>
+```text
+{% assign username = "John G. Chalmers-Smith" %}

+  Hello there!

+title: divided_by
+description: Liquid filter that divides a number by another number.
+---
+
+Divides a number by another number.
+
+The result is rounded down to the nearest integer (that is, the [floor]({{ "/filters/floor/" | prepend: site.baseurl }})) if the divisor is an integer.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}

+```text
+{{ 16 | divided_by: 4 }}
+{{ 5 | divided_by: 3 }}
+```
+
+### Controlling rounding
+
+`divided_by` produces a result of the same type as the divisor — that is, if you divide by an integer, the result will be an integer. If you divide by a float (a number with a decimal in it), the result will be a float.
+
+For example, here the divisor is an integer:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ 20 | divided_by: 7 }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ 20 | divided_by: 7 }}

+
+Here it is a float:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ 20 | divided_by: 7.0 }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ 20 | divided_by: 7.0 }}
+```
+
+### Changing variable types
+
+You might want to use a variable as a divisor, in which case you can't simply add `.0` to convert it to a float. In these cases, you can `assign` a version of your variable converted to a float using the `times` filter.
+
+In this example, we're dividing by a variable that contains an integer, so we get an integer:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_integer = 7 %}
+{{ 20 | divided_by: my_integer }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% assign my_integer = 7 %}
+{{ 20 | divided_by: my_integer }}
+```
+
+Here, we [multiply]({{ "/filters/times/" | prepend: site.baseurl }}) the variable by `1.0` to get a float, then divide by the float instead:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_integer = 7 %}
+{% assign my_float = my_integer | times: 1.0 %}

+Control flow tags create conditions that decide whether blocks of Liquid code get executed.
+
+## if
+
+Executes a block of code only if a certain condition is `true`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% if product.title == "Awesome Shoes" %}
+  These shoes are awesome!
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+These shoes are awesome!
+```
+
+## unless
+
+The opposite of `if` – executes a block of code only if a certain condition is **not** met.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% unless product.title == "Awesome Shoes" %}
+  These shoes are not awesome.
+{% endunless %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+These shoes are not awesome.
+```
+
+This would be the equivalent of doing the following:
+
+```liquid
+{%- raw -%}
+{% if product.title != "Awesome Shoes" %}
+  These shoes are not awesome.
+{% endif %}
+{% endraw %}
+```
+
+## elsif / else
+
+Adds more conditions within an `if` or `unless` block.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+<!-- If customer.name = "anonymous" -->
+{% if customer.name == "kevin" %}

+  Hey Anonymous!
+{% else %}
+  Hi Stranger!
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+Hey Anonymous!
+```
+
+## case/when
+
+Creates a switch statement to execute a particular block of code when a variable has a specified value. `case` initializes the switch statement, and `when` statements define the various conditions.
+
+A `when` tag can accept multiple values. When multiple values are provided, the expression is returned when the variable matches any of the values inside of the tag. Provide the values as a comma-separated list, or separate them using an `or` operator.
+
+An optional `else` statement at the end of the case provides code to execute if none of the conditions are met.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign handle = "cake" %}

+  {% when "cake" %}

+Uses for `cycle` include:
+
+- applying odd/even classes to rows in a table
+- applying a unique class to the last product thumbnail in a row
+
+## cycle (parameters)
+
+`cycle` accepts a "cycle group" parameter in cases where you need multiple `cycle` blocks in one template. If no name is supplied for the cycle group, then it is assumed that multiple calls with the same parameters are one group.

+
+Template tags tell Liquid where to disable processing for comments or non-Liquid markup, and how to establish relations among template files.
+
+## comment
+
+Allows you to leave un-rendered code inside a Liquid template. Any text within the opening and closing `comment` blocks will not be printed, and any Liquid code within will not be executed.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}

+
+## Inline comments {%- include version-badge.html version="5.4.0" %}
+
+You can use inline comments to prevent an expression from being rendered or output. Any text inside of the tag also won't be rendered or output.
+
+You can create multi-line inline comments. However, each line must begin with a `#`.
+
+<p class="code-label">Input</p>
+```liquid

+
+<p class="code-label">Output</p>
+```text
+
+

+
+### Inline comments inside `liquid` tags
+
+You can use the inline comment tag inside [`liquid` tags](#liquid). The tag must be used for each line that you want to comment.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}

+
+## raw
+
+Temporarily disables tag processing. This is useful for generating certain content that uses conflicting syntax, such as [Mustache](https://mustache.github.io/) or [Handlebars](https://handlebarsjs.com/).
+
+<p class="code-label">Input</p>
+```liquid

+Encloses multiple tags within one set of delimiters, to allow writing Liquid logic more concisely.
+
+```liquid

+Because any tag blocks opened within a `liquid` tag must also be closed within the same tag, use [`echo`](#echo) to output data.
+
+## echo {%- include version-badge.html version="5.0.0" %}
+
+Outputs an expression in the rendered HTML. This is identical to wrapping an expression in `{% raw %}{{{% endraw %}` and `{% raw %}}}{% endraw %}`, but works inside [`liquid`](#liquid) tags and supports [filters]({{ "/basics/introduction/#filters" | prepend: site.baseurl }}).
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% liquid
+for product in collection.products
+  echo product.title | capitalize
+endfor %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+Hat Shirt Pants
+```
+
+## render {%- include version-badge.html version="5.0.0" %}
+
+Insert the rendered content of another template within the current template.
+
+```liquid
+{%- raw -%}
+{% render "template-name" %}
+{% endraw %}
+```
+
+Note that you don't need to write the file's `.liquid` extension.
+
+The code within the rendered template does **not** automatically have access to the variables assigned using [variable tags]({{ "/tags/variable/" | prepend: site.baseurl }}) within the parent template. Similarly, variables assigned within the rendered template cannot be accessed by code in any other template.
+
+## render (parameters)
+
+Variables assigned using [variable tags]({{ "/tags/variable/" | prepend: site.baseurl }}) can be passed to a template by listing them as parameters on the `render` tag.
+
+```liquid
+{%- raw -%}
+{% assign my_variable = "apples" %}
+{% render "name", my_variable: my_variable, my_other_variable: "oranges" %}
+{% endraw %}
+```
+
+One or more objects can be passed to a template.
+
+```liquid
+{%- raw -%}
+{% assign featured_product = all_products["product_handle"] %}
+{% render "product", product: featured_product %}
+{% endraw %}
+```
+
+### with
+
+A single object can be passed to a template by using the `with` and optional `as` parameters.
+
+```liquid
+{%- raw -%}
+{% assign featured_product = all_products["product_handle"] %}
+{% render "product" with featured_product as product %}
+{% endraw %}
+```
+
+In the example above, the `product` variable in the rendered template will hold the value of `featured_product` from the parent template.
+
+### for
+
+A template can be rendered once for each value of an enumerable object by using the `for` and optional `as` parameters.
+
+```liquid
+{%- raw -%}
+{% assign variants = product.variants %}
+{% render "product_variant" for variants as variant %}
+{% endraw %}
+```
+
+In the example above, the template will be rendered once for each variant of the product, and the `variant` variable will hold a different product variant object for each iteration.
+
+When using the `for` parameter, the [`forloop`]({{ "/tags/iteration/#forloop-object" | prepend: site.baseurl }}) object is accessible within the rendered template.
+
+## include
+
+_The `include` tag is deprecated; please use [`render`](#render) instead._
+
+Insert the rendered content of another template within the current template.
+
+```liquid
+{%- raw -%}
+{% include "template-name" %}
+{% endraw %}
+```
+
+The `include` tag works similarly to the [`render`](#render) tag, but it allows the code inside of the rendered template to access and overwrite the variables within its parent template. It has been deprecated because the way that it handles variables reduces performance and makes Liquid code harder to both read and maintain.
+
+Note that when a template is rendered using the [`render`](#render) tag, the `include` tag cannot be used within the template.

+title: Variable
+description: An overview of tags for creating variables in the Liquid template language.
+---
+
+Variable tags create new Liquid variables.
+
+## assign
+
+Creates a new named variable.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_variable = false %}
+{% if my_variable != true %}
+  This statement is valid.
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+This statement is valid.
+```
+
+Wrap a value in quotations `"` to save it as a string variable.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign foo = "bar" %}
+{{ foo }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% assign foo = "bar" %}
+{{ foo }}
+```
+
+## capture
+
+Captures the string inside of the opening and closing tags and assigns it to a variable. Variables created using `capture` are stored as strings.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% capture my_variable %}I am being captured.{% endcapture %}
+{{ my_variable }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+I am being captured.
+```
+
+Using `capture`, you can create complex strings using other variables created with `assign`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign favorite_food = "pizza" %}
+{% assign age = 35 %}
+
+{% capture about_me %}
+I am {{ age }} and my favorite food is {{ favorite_food }}.
+{% endcapture %}
+
+{{ about_me }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+I am 35 and my favourite food is pizza.
+```
+
+## increment
+
+Creates and outputs a new number variable with initial value `0`. On subsequent calls, it increases its value by one and outputs the new value.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% increment my_counter %}
+{% increment my_counter %}
+{% increment my_counter %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% increment my_counter %}
+{% increment my_counter %}
+{% increment my_counter %}
+```
+
+Variables created using `increment` are independent from variables created using `assign` or `capture`.
+
+In the example below, a variable named "var" is created using `assign`. The `increment` tag is then used several times on a variable with the same name. Note that the `increment` tag does not affect the value of "var" that was created using `assign`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign var = 10 %}
+{% increment var %}
+{% increment var %}
+{% increment var %}
+{{ var }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% assign var = 10 %}
+{% increment var %}
+{% increment var %}
+{% increment var %}
+{{ var }}
+```
+
+## decrement
+
+Creates and outputs a new number variable with initial value `-1`. On subsequent calls, it decreases its value by one and outputs the new value.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% decrement variable %}
+{% decrement variable %}
+{% decrement variable %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% decrement variable %}
+{% decrement variable %}
+{% decrement variable %}
+```
+
+Like [increment](#increment), variables declared using `decrement` are independent from variables created using `assign` or `capture`.
