I want to start a completely new project using version control

To start using version control for an initially empty project, just initialise a repository in an empty folder:

1. Click the Open toolbar button or use File -> Open

2. Select “File folder” as the thing you want to open

3. Make a new folder in the file dialog and browse to it

4. Click OK

A new repository will be created, stowed into the empty working folder you selected. At first, it will have an empty history. You can then start to add and commit changes to your files.
