With BitTorrent Sync it is easy to share a git repository in read-only or read-write mode. While it has always been possible to push a copy of your repository to a web server via ssh, configuring access control can be a burden when first starting a project.

Here's the basic steps:

1. Install btsync.

2. Create a bare repository. You won't do any work in this directory, but instead it will act as a remote where you will push and pull.

   git init --bare ~/projects/secret.git
   

3. Checkout a copy of your repository:

   git clone ~/projects/secret.git ~/projects/secret
   

   This will create a new directory called secret.

4. Create your first commit in the secret directory.

   echo world domination plans > README
   git add README
   git commit -m 'first commit'
   

5. Push it to the secret.git directory.

   git push
   

6. Add the secret.git directory to btsync. btsync will give you an read-only key that you can share with minions, or a read-write key that you can share with covillains.

7. The other person adds the key into the btsync app and has it sync to the ~/projects/secret.git directory.

8. The other person checks out a local copy.

   git clone ~/projects/secret.git ~/projects/secret
   

9. The other person can now work as normal. If she has the read-write key, she can push directly back into the repository.

10. btsync will keep the secret.git changes in sync. It normally syncs instantly.

Notes:

• If neither you nor your peer leave your computer on all the time then you can install btsync on your phone and sync the bare repository there as well.

• If someone with a read-only key wants to contribute back, she needs to create her own bare repository and push her changes there, and then share the read-only key back to the original author. He can then examine her changes and merge them if desired.
