1. have a brilliant idea for something you want to use
2. Stop! Don't start building it. 
3. Find a project that does something similar. (This likely exists)
4. Read it's documentation. 
  * If it has none, learn the project and create some. 
  * If it does, try to build something with it and document what wasn't clear. 
5. If it feels broke. Write some failing tests, 
  * If possible, fix them, then open a pr
  * If not, open a pr with failing tests and get the maintainer to teach you how to fix them 
6. Document your process for contributing in a file called CONTIBUTING.md
