 If necessary the post-receive hook has to be updated via scp.
 
+## Troubleshooting
+
+If this setup is recreated there might be an issue with the bare repo on the 
+server assuming that we are using a `master` branch, when we instead have a 
+main branch. This issue might present itself, if the post-receive hook outputs
+```
+remote: fatal: You are on a branch yet to be born
+```
+
+We can fix this by editing the HEAD file in the bare repo to contain this line:
+```
+ref: refs/heads/main > HEAD
+```
