Alasdairs, Welcome to Servoy in 2024!
If you registered recently, you should have received a ServoyCloud account. This includes git hosting and when you sign into Servoy Developer, it will also connect to your project (via a simplified, built-in git client).
However, Servoy works with any repository and git client. If you use another client you can simply choose file > import > general > existing projects into workspace. Select your projects found in your local repo folder.
I hope this helps.
Best,
Sean
