 Before rendering a template, you can configure the internal templating engine using the `Render` instance's variable `environment`, which is an instance of jinja2 **[Environment][3]** class. For example, to declare a custom filter use:

+### Features of jinja2 not supported
+Secretary supports most of the jinja2 control structure/flow tags. But please avoid using the following tags since they are not supported: `block`, `extends`, `macro`, `call`, `include` and `import`.
+
 ### Builtin Filters
 Secretary includes some predefined *jinja2* filters. Included filters are:
 
-- **markdown(value)**   
+- **markdown(value)**
 Convert the value, a markdown formated string, into a ODT formated text. Example:
 
         {{ invoice.description|markdown }}
- 
-- **pad(value, length)**   
+
+- **pad(value, length)**
 Pad zeroes to `value` to the left until output value's length be equal to `length`. Default length if 5. Example:
 
         {{ invoice.number|pad(6) }}
