This is exactly the same steps I follow. I created this project and along the way, contributed to one of the dependencies. github.com/kodaman2/Data_Preserve

Another way to start your own repo is to think about things you do in your everyday life or work that are repetitive and might be easily replaced with a program.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
