If it's a small project, then a quick email to the maintainer or a GitHub issue asking how to get involved would be great. More often than not the maintainers would gladly help you.

If it's a large project then the above would be slightly annoying. The maintainers would more than likely have some sort of process for contributors to get involved in their CONTRIBUTING.md file. If not, then creating that file is a great place to get started!

Also, you could just go direct and submit a PR. But only do this if you know that it's within the scope of the project. Adding an enterprise feature to a small project isn't going to go down well.

I used to be quite scared of contributing because I didn't know if my contribution was good enough. But I quickly learnt that the maintainers do it for the love of the project and anyone contributing is like them showing love for the project too!

Other than that, enjoy it. Don't fret the small stuff! Happy contributing!
