Hi David! Besides listed suggestions there are some another options to work with git from Cache Studio:

1. sc.plugin - Studio hooks tool for exporting/importing COS code in UDL format

2. source control - very simple Studio hooks implementation to export/import in xml format.

To work with github repos and source files you can try github desktop:

Create new repo on github and then click 'Install github Desktop' button as shown here.

Follow instructions.
