+Did you clone the repository?
+
+    $ git clone git://git-annex.branchable.com/ git-annex
+
+I see lots of branches (remember they are *remote* branches so you will need the `-a` flag):
+
+    $ git branch -a
+    * master
+      remotes/origin/HEAD -> origin/master
+      remotes/origin/atomic-store-test
+      remotes/origin/debian
+      remotes/origin/debian-jessie-backport
+      remotes/origin/debian-squeeze-backport
+      remotes/origin/debian-stable-security-fix
+      remotes/origin/debian-wheezy-backport
+      remotes/origin/ghc7.0
+      remotes/origin/improved-smudge-filters
+      remotes/origin/master
+      remotes/origin/newwinrelease
+      remotes/origin/no-direct-mode
+      remotes/origin/p2p-map
+      remotes/origin/setup
+      remotes/origin/smudge
+      remotes/origin/tweak-fetch
+      remotes/origin/uuid-type-rework
+      remotes/origin/winsplicehack
+
+You can checkout one of the branches like:
+
+    $ git checkout remotes/origin/setup
+
+Does that help?
