+Those who are familiar with XSLT may notice that Genshi templates bear some similarities. However, there are some Trac specific features - for example '''${href.chrome('site/style.css')}''' attribute references template placed into environment's ''htdocs/''  In a similar fashion '''${chrome.htdocs_location}''' is used to specify common ''htdocs/'' directory from Trac installation.

+site.html is one file to contain all your modifications. It usually works by the py:match (element of attribute), and it allows you to modify the page as it renders - the matches hook onto specific sections depending on what it tries to find
+and modify them. A site.html can contain any number of such py:match sections for whatever you need to modify. This is all [http://genshi.edgewall.org/ Genshi], so the docs on the exact syntax can be found there.

-If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can actually be loaded by using a workaroud - providing it contains no ClearSilver processing. In addition, as only one element can be imported, the content needs some sort of wrapper such as a `<div>` block or other similar parent container. The XInclude namespace must be specified to allow includes, but that can be moved to document root along with the others:
+This example illustrates a technique of using '''`req.environ['PATH_INFO']`''' to limit scope of changes to one view only. For instance, to make changes in site.html only for timeline and avoid modifying other sections - use  ''`req.environ['PATH_INFO'] == '/timeline'`'' condition in <py:if> test.

 Trac resolves requests for a template by first looking inside the project, then in any inherited templates location, and finally inside the Trac egg.
 
+Trac caches templates in memory by default to improve performance. To apply a template you need to restart the server.
