How can I help?
If you speak a non-English language, and your knowledge of the English language is sufficient, then you can help out by translating the project into your language. This can be done on Transifex. If you want to help out and translate the project into a language that isn't listed yet, contact me at firstname.lastname@example.org so I can add that language to the project.
