 === External Systems
 
+Git comes with a few commands to integrate with other version control systems.
+
 ==== svn
 
+The `git svn` command is used to communicate with the Subversion version control system as a client. This means you can use Git to checkout from and commit to a Subversion server.
+
+This command is covered in depth in <<_git_svn>>.
+
 ==== fast-import
 
+For other version control systems or importing from nearly any format, you can use `git fast-import` to quickly map the other format to something Git can easily record.
+
+This command is coverd in depth in <<_custom_importer>>.
