All contributions are welcome: ideas, patches, documentation, bug reports, complaints, and even something you drew up on a napkin.
Programming is not a required skill. Whatever you've seen about open source and maintainers or community members saying "send patches or die" - you will not see that here.
It is more important to the community that you are able to contribute.
