How to Sync a Wiki between Repositories

This is a quick guide to mirroring a Project Wiki to another repository.

# Clone the wiki
git clone <source wiki repo url>

# Add mirror repository as a remote
cd <source wiki repo working folder>
git remote add mirror <mirror repo that must already exist>

Now each time you wish to sync run the following to get latest from the source wiki repo:

# Get everything
git pull -v

Warning: Check that the output of the pull shows "From source repo URL". If this shows the mirror repo url then you've forgotten to reset the tracking. Run git branch -u origin/wikiMaster then continue.

Then run this to push it to the mirror repo and reset the branch to track the source repo again:

# Push all branches up to mirror remote
git push -u mirror

# Reset local to track source remote
git branch -u origin/wikiMaster

Your output should look like this when run:

PS C:\Git\MyProject.wiki> git pull -v
