+Gerrit2 - Command Line Tool
+===========================
+
+Executing Commands
+------------------
+
+Aside from the standard Git server side actions, Gerrit supports
+several other commands over its internal SSH daemon. As Gerrit does
+not provide an interactive shell, the commands must be triggered
+from an ssh client, for example:
+
+ $ ssh -p 29418 review.example.com gerrit ls-projects
+
+For more details on how to determine the correct SSH port number,
+see link:user-upload.html#test_ssh[Testing Your SSH Connection].
+
+User Commands
+-------------
+
+git upload-pack::
+ Standard Git server side command for client side `git fetch`.
+
+git receive-pack::
+ Standard Git server side command for client side `git push`.
++
+Also implements the magic associated with uploading commits for
+review. See link:user-upload.html#push_create[Creating Changes].
