+So you have two computers in the same building, and you want them to share
+the same synchronised folder, communicating directly with each other.
+
+This is incredibly easy to set up with the git annex assistant.
+
+Let's say the two computers are your computer and your friend's computer.
+We'll start on your computer, where you open up your git annex dashboard.
+
+[[!img addrepository.png alt="Add another repository button"]]
+
+`*click*`
+
+[[!img pairing.png alt="Pair with another computer"]]
+
+`*click*`
+
+Now the hard bit. You have to think up a secret phrase, and type it in,
+(and perhaps get the spelling correct).
+
+[[!img secret.png alt="Enter secret phrase"]]
+
+Now your computer is in pairing mode. When your friend looks at her git
+annex dashboard, she sees something like this.
+
+[[!img pairrequest.png alt="Pair request"]]
+
+`*click*`
+
+[[!img secretempty.png alt="Enter same secret phrase"]]
+
+Now it's up to you to let her know what the secret is. As soon as she
+enters it, both your computers will be paired, and will begin to sync their
+git-annex folders. Just like that you can share files.
+
+----
+
+Something to keep in mind, especially if pairing doesn't seem to be
+working, is that the two computers need to be on the same network for this
+pairing process to work. Sometimes a building will have more than one
+network inside it, and you'll need to connect them both to the same one.
+Make sure the wireless network name is the same, or that they're both
+plugged into the same router.
+
+Also, the file sharing set up by this pairing only works when both
+computers are on the same network. If you go on a trip, any files you
+edit will not be visible to your friend until you get back. 
+
+To get around this, you'll often also want to set up
+[[jabber_pairing|share_with_a_friend_walkthrough]], and a server
+in the cloud, which they can use to exchange files while away.
+
+And also, you can pair with as many other computers as you like, not just
+one!
+
+## What does pairing actually do behind the scenes?
+
+It ensures that both repositories have correctly configured 
+[[remotes|walkthrough/adding_a_remote]] pointing to each other.
+If you have already configured this manually, you do not need to
+perform pairing.
