 The OWASP CRS documentation is generated as a Sphinx project and is stored in a separate Github repository. While the documentation is available as part of the CRS project it is provided in the form of a git-submodule. Using a git-submodule allow us to update the documentation without making changes to the main rule repository.
 
 You can download the documentation using git:
-	$ git submodule init
+    $ git submodule init
     $ git submodule update
