I've created one project that no one uses. I've found a lot of friction contributing to existing projects. There has to be:

• something to do
• the maintainer is cool with having it done
• the maintainer is okay not doing it themselves
• is within my expertise or requires an acceptable amount of ramp up learning

Then I have to make sure to learn their code of conduct and do it exactly the way they want. Do they want testing? Do they want me to update the docs? So I have to get green light from maintainer to start? Etc.
