I am a programmer who is visually impaired.  I set up devstack on a Digital Ocean droplet on Ubuntu 20.04 Server.  It installed successfully.  I am trying to make a contribution on 1599140.  So my questions are:

1. How do I set up a development environment for this or any other contribution?

2. Do I work directly on the droplet and push from to the repo from there?

Any assistance will be of tremendous help.
