 ## via Options
 
-[liquidjs][liquidjs] will **NOT** trim any whitespace by default.
+To enable whitespace control without spreading changes, use these options:
-By specifying `options.trim_left` or `options.trim_right`, 
-you can change this default behavior. 
 
-Note that the `trim_right` and `trim_left` only change the behavior of `{{ }}` and `{% %}`,
+* `trim_tag_left`
-which means `{{-` (or `{%-`) will always trim whitespace from the left, 
+* `trim_tag_right`
-and `-}}` (or `-%}`) will always trim whitespace from the right regardless of the `trim_left` and `trim_right` options.
+* `trim_value_right`
+* `trim_value_right`
 
-For details of these options, see: <https://github.com/harttle/liquidjs>
+[liquidjs][liquidjs] will **NOT** trim any whitespace by default, i.e. above options all default to `false`.
+For details of these options, see the [README](https://github.com/harttle/liquidjs).
 
+## Greedy Mode
+
+In greedy mode (enabled by the [greedy option][liquidjs]),
+all consecutive whitespace chars (including `\n`) will be trimmed.
+Greedy mode is enabled by default to be compliant with [shopify/liquid][shopify/liquid].
