-A Liquid template engine with a wide range of tags and filters,
-for both Node.js and browsers.
-Here's a live demo: <http://harttle.com/shopify-liquid/>
+This is a liquid implementation for both Node.js and browsers. Website: <http://harttle.github.io/liquidjs/>, Live Demo: <https://jsfiddle.net/6u40xbzs/> 
 
-> The Liquid template engine is implemented in Ruby originally, 
-> which is used by [Jekyll][jekyll] and [Github Pages][gh].
+**Features**
 
-Features:
+* Fully compatible to [shopify][shopify/liquid], with all [tags][tags] and [filters][filters] implemented
+* Support layout(extend) and include syntax
+* In pure JavaScript with Promise-based API
 
-* A wide range of [filters](https://github.com/harttle/shopify-liquid/wiki/Builtin-Filters) and [tags](https://github.com/harttle/shopify-liquid/wiki/Builtin-Tags)
-* Easy tag/filter registration, allows async tags
-* [any-promise][any-promise]
+**Differences**
 
-API Reference:
+Though being compatible with [Ruby Liquid](https://github.com/shopify/liquid) is one of our priorities, there're still certain differences. You may need some configuration to get it compatible in these senarios:
 
-* Builtin Tags: <https://github.com/harttle/shopify-liquid/wiki/Builtin-Tags>
-* Builtin Filters: <https://github.com/harttle/shopify-liquid/wiki/Builtin-Filters>
-* Operators: <https://github.com/harttle/shopify-liquid/wiki/Operators>
-* Whitespace Control: <https://github.com/harttle/shopify-liquid/wiki/Whitespace-Control>
+* Dynamic file locating (enabled by default), which means layout/partial name can be an variable in liquidjs. See [#51](https://github.com/harttle/liquidjs/issues/51).
+* Truthy and Falsy. All values except `undefined`, `null`, `false` are truthy, whereas in Ruby Liquid all except `nil` and `false` are truthy. See [#26](https://github.com/harttle/liquidjs/pull/26).
+* Number Rendering. Since JavaScript do not distinguish `float` and `integer`, we cannot either convert between them nor render regarding to their type. See [#59](https://github.com/harttle/liquidjs/issues/59).
+* [.to_liquid()](https://github.com/Shopify/liquid/wiki/Introduction-to-Drops) has a `.toLiquid()` alias and and the JavaScript `.toString()` is aliased to `.to_s()`.
+* [.to_s()](https://www.rubydoc.info/gems/liquid/Liquid/Drop) uses `JSON.prototype.stringify` as default, rather than Ruby's inspect.

 ## Render from String
 
+Install as Node.js dependency:
+
+```bash
+# You'll need a promise-polyfill for Node.js < 4
+npm install --save liquidjs
+```
+
 Parse and Render:
 
 ```javascript
-var Liquid = require('shopify-liquid');
-var engine = Liquid();
+var Liquid = require('liquidjs');
+var engine = new Liquid();
 
-engine.parseAndRender('{{name | capitalize}}', {name: 'alice'})
-    .then(function(html){
-        // html === 'Alice'
-    });
+engine
+    .parseAndRender('{{name | capitalize}}', {name: 'alice'})
+    .then(console.log);
+
+// outputs 'Alice'
 ```
 
 Caching templates:
 
 ```javascript
 var tpl = engine.parse('{{name | capitalize}}');
-engine.render(tpl, {name: 'alice'})
-    .then(function(html){   
-        // html === 'Alice'
-    });
+engine
+    .render(tpl, {name: 'alice'})
+    .then(console.log);
+
+// outputs 'Alice'
 ```
 
 ## Render from File
 
 ```javascript
-var engine = Liquid({
+var engine = new Liquid({
     root: path.resolve(__dirname, 'views/'),  // dirs to lookup layouts/includes
-    extname: '.liquid'          // the default extname used for layouts/includes
+    extname: '.liquid'          // the extname used for layouts/includes, defaults ""
 });
 engine.renderFile("hello.liquid", {name: 'alice'})
-    .then(function(html){
-       // html === 'Alice'
-    });
-// equivalent to: 
-engine.renderFile("hello", {name: 'alice'})
-    .then(function(html){
-       // html === 'Alice'
-    });
+    .then(console.log)  // outputs "Alice"
+
+// which is equivalent to: 
+engine
+    .renderFile("hello", {name: 'alice'})
+    .then(console.log)  // outputs "Alice"
 ```
 
-## Options
-
-The full list of options for `Liquid()` is listed as following:
-
-* `root` is a directory or an array of directories to resolve layouts and includes, as well as the filename passed in when calling `.renderFile()`.
-If an array, the files are looked up in the order they occur in the array.
-Defaults to `["."]`
-
-* `extname` is used to lookup the template file when filepath doesn't include an extension name. Defaults to `".liquid"`
-
-* `cache` indicates whether or not to cache resolved templates. Defaults to `false`.
-
-* `strict_filters` is used to enable strict filter existence. If set to `false`, undefined filters will be rendered as empty string. Otherwise, undefined filters will cause an exception. Defaults to `false`.
-
-* `strict_variables` is used to enable strict variable derivation. 
-If set to `false`, undefined variables will be rendered as empty string.
-Otherwise, undefined variables will cause an exception. Defaults to `false`.
-
-* `trim_right` is used to strip blank characters (including ` `, `\t`, and `\r`) from the right of tags (`{% %}`) until `\n` (inclusive). Defaults to `false`.
-
-* `trim_left` is similiar to `trim_right`, whereas the `\n` is exclusive. Defaults to `false`. See [Whitespace Control][whitespace control] for details.
-
-* `greedy` is used to specify whether `trim_left`/`trim_right` is greedy. When set to `true`, all successive blank characters including `\n` will be trimed regardless of line breaks. Defaults to `false`.
