+BUILDBOT
+========
+
+The buildbot client can be used to test changes before committing, with
+"buildbot try".
+
+-   Ask for a buildbot account
+
+-   Install the buildbot client
+
+-   Configure it, e.g.:
+
+    ~~~~~
+    $ cat ~/.buildbot/options
+    try_master = 'radia.quagga.net:8031'
+    try_username = 'paul'
+    try_password = 'password123'
+    try_vc = 'git'
+    try_branch = 'master'
+    try_wait = True
+    $ buildbot try -c pb --get-builder-names
+    using 'pb' connect method
+    The following builders are available for the try scheduler: 
+    build-fedora-24
+    ...
+    ~~~~~
+
+-   You can then submit your local changes to try build:
+
+    ~~~~
+    $ buildbot try -c pb
+    ~~~~
+
+    or use the -b argument to limit to a specific builder (recommended).
+
+    ~~~~~
+    $ buildbot try -c pb -b build-distcheck
