Hello, still finding an issue with forking, anyone to assist me. converting format to raw gives me sort of json, do I even need to fork at all or I can start from my clean notebook?

Hello all,
Am Tumusiime Ezra from Uganda
Am very comfortable with Django rest framework, React, and Vuejs.
Would like to attempt both tasks but my question is, how do I finally contribute my codebase?
Do I push to GitHub?
