+=== Some Useful Tips
+
+ - Place your environment's directory on a filesystem which supports sub-second timestamps, as Trac monitors the timestamp of its configuration files and changes happening on a filesystem with too coarse-grained timestamp resolution may go undetected in Trac < 1.0.2 (this is also true for the location of authentication files when using TracStandalone).
+
+ - The user under which the web server runs will require file system write permission to 
+ the environment directory and all the files inside. Please remember to set
+ the appropriate permissions. The same applies to the source code repository, 
+ although the user under which Trac runs will only require write access to a Subversion repository created with the BDB file system; for other repository types, check the corresponding plugin's documentation. 
+ 
+ - `initenv`, when using an svn repository, does not imply that trac-admin will perform `svnadmin create` for the specified repository path. You need to perform the `svnadmin create` prior to `trac-admin initenv` if you're creating a new svn repository altogether with a new trac environment, otherwise you will see a message "Warning: couldn't index the repository" when initializing the environment.
+
+ - Non-ascii environment paths are not supported
+ 
+ - Also, it seems that project names with spaces can be problematic for authentication (see [trac:#7163]).
+
+ - TracPlugins located in a [TracIni#inherit-section shared plugins folder] that is defined in an [TracIni#GlobalConfiguration inherited configuration] are currently not loaded during creation, and hence, if they need to create extra tables for example, you'll need to [TracUpgrade#UpgradetheTracEnvironment upgrade the environment] before being able to use it.

 == Source Code Repository ==
 
-You'll first have to provide the ''type'' of your repository (e.g. `svn` for Subversion,
-which is the default), then the ''path'' where the repository is located.
+Since version 0.12, a single Trac environment can be connected to more than one repository. There are many different ways to connect repositories to an environment, see TracRepositoryAdmin. This page also details the various attributes that can be set for a repository (like `type`, `url`, `description`).
 
-If you don't want to use Trac with a source code repository, simply leave the ''path'' empty
-(the ''type'' information doesn't matter, then).
+In Trac 0.12 `trac-admin` no longer asks questions related to repositories. Therefore, by default Trac is not connected to any source code repository, and the ''Browse Source'' toolbar item will not be displayed.
+You can also explicitly disable the `trac.versioncontrol.*` components (which are otherwise still loaded)
+{{{
+[components]
+trac.versioncontrol.* = disabled
+}}}
 
-For some systems, it is possible to specify not only the path to the repository,
+For some version control systems, it is possible to specify not only the path to the repository,
 but also a ''scope'' within the repository. Trac will then only show information
 related to the files and changesets below that scope. The Subversion backend for
 Trac supports this; for other types, check the corresponding plugin's documentation.

+structure, but those are two disjoint entities and they are not and ''must not'' be located at the same place.
