    1617=== Logo ===
    17 Change the `src` setting to `site/` followed by the name of your image file.  The `width` and `height` settings should be modified to match your image's dimensions (the Trac chrome handler uses "`site/`" for files within the project directory `htdocs` and "`common/`" for the common ones).
     18Change the `src` setting to `site/` followed by the name of your image file.  The `width` and `height` settings should be modified to match your image's dimensions (the Trac chrome handler uses "`site/`" for files within the project directory `htdocs`, and "`common/`" for the common `htdocs` directory belonging to a Trac installation). Note that 'site/' is not a placeholder for your project name, it is the actual prefix that should be used (literally). For example, if your project is named 'sandbox', and the image file is 'red_logo.gif' then the 'src' setting would be 'site/red_logo.gif', not 'sandbox/red_logo.gif'.

    2728=== Icon ===
    28 Icons should be a 16x16 image in `.gif` or `.ico` format.  Change the `icon` setting to `site/` followed by the name of your icon file.  Icons will typically be displayed by your web browser next to the site's URL and in the `Bookmarks` menu.
     29Icons should be a 32x32 image in `.gif` or `.ico` format.  Change the `icon` setting to `site/` followed by the name of your icon file.  Icons will typically be displayed by your web browser next to the site's URL and in the `Bookmarks` menu.

    4250== Custom Navigation Entries ==
    4351The new [mainnav] and [metanav] can now be used to customize the text and link used for the navigation items, or even to disable them (but not for adding new ones).

    45 In the following example, we rename the link to the Wiki start "Home", and hide the "Help/Guide". We also make the "View Tickets" entry link to a specific report .

    93 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.
    94 
    95 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
    96 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.

However, there are some Trac specific features - for example `${href.chrome('site/style.css')}` attribute references a CSS file placed into environment's `htdocs/` directory. In a similar fashion `${chrome.htdocs_location}` is used to specify the common `htdocs/` directory belonging to a Trac installation. That latter location can however be overriden using the [[TracIni#trac-config|[trac] htdocs_location]] configuration setting.

     103`site.html` is one file to contain all your modifications. It usually works using the `py:match` directive (element or 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
     104and modify them.
     105See [http://groups.google.com/group/trac-users/browse_thread/thread/70487fb2c406c937/ this thread] for a detailed explanation of the above example `site.html`.
     106A `site.html` can contain any number of such `py:match` sections for whatever you need to modify. This is all Genshi, so the [http://genshi.edgewall.org/wiki/Documentation/xml-templates.html docs on the exact syntax] can be found there.

    111 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.

    113126If 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:

    125 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.
