+Like other variants of Liquid, shopify-liquid supports whitespace control markups.
+In addition, you can change the default behaviors during construction.
+
+## via Markups
+
+By default, all tags and output markups lines will generate a CR,
+and whitespace if there's an indentation. 
+For example:
+
+```liquid
+{% assign author = "harttle" %}
+{{ author }}
+```
+
+Outputs:
+
+```
+
+harttle
+```
+
+You can include hyphens in your tag syntax (`{{-`, `-}}`, `{%-`, `-%}`) to
+strip whitespace from left or right. For example:
+
+```liquid
+{% assign author = "harttle" -%}
+{{ author }}
+```
+
+Outputs
+
+```
+harttle
+```
+
+> In this case, the `-%}` strips the whitespace from the right side of the `assign` tag.
+
+## via Options
+
+[shopify-liquid][shopify-liquid] will **NOT** trim any whitespace by default.
+By specifying `options.trim_left` or `options.trim_right`, 
+you can change this default behavior.
