Branch Based Workflow for QGis

This workflow might be useful for you if:

  • you work on multiple features/bugs at a time
  • you do not have write permission at the qgis repository(you can only issue pull requests).

This workflow is strictly branch based. That is, you are never going to do any real work in master.

  1. Login to GitHub

  3. Create a local folder and switch to it
  4. mkdir qgisdev
    cd qgisdevgit

Here are some screens of the current working version. It is in the early stages, so don’t get frustrated with its bugs if you happen to see it in Qgis.
