+= The Trac Environment =
+
+Trac uses a directory structure and a database for storing project data. The directory is referred to as the “environment”.
+
+== Creating an Environment ==
+
+A new Trac environment is created using [wiki:TracAdmin trac-admin]:
+{{{
+$ trac-admin /path/to/projectenv initenv
+}}}
+
+[wiki:TracAdmin trac-admin] will ask you for the name of the project, the
+database connection string (explained below), and the type and path to
+your source code repository.
+
+''Note: The web server user 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 Subversion repository 
+Trac is eventually using, although Trac will only require read access as long 
+as you're not using the BDB file system.''
+
+== Database Connection Strings ==
+
+Since version 0.9, Trac supports both [http://sqlite.org/ SQLite],
+[http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ MySQL] as
+database backends.  The default is to use SQLite, which is probably sufficient
+for most projects. The database file is then stored in the environment
+directory, and can easily be [wiki:TracBackup backed up] together with the
+rest of the environment.
+
+The connection string for an embedded SQLite database is:
+{{{
+sqlite:db/trac.db
+}}}
+
+If you want to use PostgreSQL or MySQL instead, you'll have to use a
+different connection string. For example, to connect to a PostgreSQL
+database on the same machine called `trac`, that allows access to the
+user `johndoe` with the password `letmein`, use:
+{{{
+postgres://johndoe:letmein@localhost/trac
+}}}
+
+If PostgreSQL is running on a non-standard port (for example 9342), use:
+{{{
+postgres://johndoe:letmein@localhost:9342/trac
+}}}
+
+Note that with PostgreSQL you will have to create the database before running
+`trac-admin initenv`.
+
+And make sure PostgreSQl DB name is "trac". What worked for me:
+And didn't work uppercase trac-user-name
+{{{
+sudo su - postgres -c createdb trac
+sudo su - postgres -c psql trac
+CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name';
+}}}
+
+(Just to remind you, if you don't have a sudo/su setup, you just need to do the createdb and psql statements. That threw me the first couple of times I read this.)
+
+== 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.
+
+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).
+
+For some 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.
+
+Example of a configuration for a Subversion repository:
+{{{
+[trac]
+repository_type = svn
+repository_dir = /path/to/your/repository
+}}}
+
+The configuration for a scoped Subversion repository would be:
+{{{
+[trac]
+repository_type = svn
+repository_dir = /path/to/your/repository/scope/within/repos
+}}}
+
+== Directory Structure ==
+
+An environment directory will usually consist of the following files and directories:
+
+ * `README` - Brief description of the environment.
+ * `VERSION` - Contains the environment version identifier.
+ * `attachments` - Attachments to wiki pages and tickets are stored here.
+ * `conf`
+   * `trac.ini` - Main configuration file. See TracIni.
+ * `db`
+   * `trac.db` - The SQLite database (if you're using SQLite).
+ * `plugins` - Environment-specific [wiki:TracPlugins plugins] (Python eggs)
+ * `templates` - Custom environment-specific templates.
+   * `site_css.cs` - Custom CSS rules.
+   * `site_footer.cs` - Custom page footer.
+   * `site_header.cs` - Custom page header.
+ * `wiki-macros` - Environment-specific [wiki:WikiMacros Wiki macros].
+
+  '''Note: don't confuse a Trac environment directory with the source code repository directory.
+It happens that the above structure is loosely modelled after the Subversion repository directory 
+structure, but they are not and ''must not'' be located at the same place.'''
