+#### `indent`
+
+Indents a given string with the given indentation pattern. If the input string has multiple lines, each line will be indented.
+
+##### Example
+
+This function can be especially useful when adding YAML snippets into other YAML documents, where indentation is important:
+
+_`input.tmpl`:_
+```
+foo:
+{{ `{"bar": {"baz": 2}}` | json | toYAML | indent "  " }}
+```
+
+```console
+$ gomplate -f input.tmpl
+foo:
+  bar:
+    baz: 2
+```
+
 #### `json`
 
 Converts a JSON string into an object. Only works for JSON Objects (not Arrays or other valid JSON types). This can be used to access properties of JSON objects.
