 Trac is using [http://genshi.edgewall.org Genshi] as the templating engine. Documentation is yet to be written, in the meantime the following tip should work.
 
 Say you want to add a link to a custom stylesheet, and then your own
-header and footer. Save the following content as 'site.html' inside your projects templates directory (each Trac project can have their own site.html), e.g. {{{/path/to/env/templates/site.html}}}:
+header and footer.  Create a file {{{/path/to/env/templates/site.html}}} or {{{/path/to/inherit/option/templates_dir/site.html}}}, with contents like this:

-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.

+Note that this references your environment's `htdocs/style.css`.

-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.
-
-If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can actually be loaded by using a workaround - 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:

 Also note that the `site.html` (despite its name) can be put in a common templates directory - see the `[inherit] templates_dir` option. This could provide easier maintainence (and a migration path from 0.10 for larger installations) as one new global `site.html` file can be made to include any existing header, footer and newticket snippets.

-The appearance of each individual Trac environment (that is, instance of a project) can be customized independently of other projects, even those hosted by the same server. The recommended way is to use a `site.html` template (see [#SiteAppearance]) whenever possible. Using `site.html` means changes are made to the original templates as they are rendered, and you should not normally need to redo modifications whenever Trac is upgraded. If you do make a copy of `theme.html` or any other Trac template, you need to migrate your modifiations to the newer version - if not, new Trac features or bug fixes may not work as expected.
-
-With that word of caution, any Trac template may be copied and customized. The default Trac templates are located inside the installed Trac egg (`/usr/lib/pythonVERSION/site-packages/Trac-VERSION.egg/trac/templates, .../trac/ticket/templates, .../trac/wiki/templates, ++`). The [#ProjectList] template file is called `index.html`, while the template responsible for main layout is called `theme.html`. Page assets such as images and CSS style sheets are located in the egg's `trac/htdocs` directory.
-
-However, do not edit templates or site resources inside the Trac egg - installing Trac again can completely delete your modifications. Instead use one of two alternatives:
- * For a modification to one project only, copy the template to project `templates` directory.
- * For a modification shared by several projects, copy the template to a shared location and have each project point to this location using the `[inherit] templates_dir =` trac.ini option.
-
-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.
