We always recommend to put all your work in git-versioning, even if you don't upload it to a remote server.

  1. Create the app using 2sxc
  2. Go to the app-folder
  3. run git init to initialize the repo
  4. commit your first work

In general, always remember to regularly re-commit your work and include the app-data (containing the schema, settings etc. in the app)
