+[[jgit-protocol]]
+=== Section protocol
+
+[[protocol.version]]protocol.version::
++
+If set, the server will accept requests from a client attempting to communicate
+using the specified protocol version. Otherwise communication falls back to version 0.
+If set in file `etc/jgit.config` this option will be used for all repositories of
+the site. It can be overridden for a given repository by configuring a different
+value in the repository's `config` file.
++
+Supported versions:
+0:: the original wire protocol.
+1:: the original wire protocol with the addition of a version string in the initial response from the server.
+2:: wire protocol version 2. Speeds up fetches from repositories with many refs by allowing the client
+    to specify which refs to list before the server lists them.

 Above, the properties can be set with values matching specific deployment topologies under test.
 The example values shown above are the currently coded default ones. For example, the `http` scheme
-above could be replaced with `https`. The framework could support differing or more properties over

+above could be replaced with `https`. The `replication_delay` property matches replication plugin's
+configuration with the same name. The framework may support differing or more properties over time.
 
 Plugin or otherwise non-core scenarios may do so just as well. The core java package
 `com.google.gerrit.scenarios` from the example above has to be replaced with the one under which
 those scenario classes are. Such extending scenarios can also add extension-specific properties.
 Examples of this can be found in these Gerrit plugins test code:
