Contribution guidelines

Our standards are pretty low, but make sure the code is not too ugly:

Run VS Code's autoformat when you're done.
Check with ESLint by running npm run lint, then fix the errors.
Use common sense and follow existing naming conventions.

Create pull requests for the staging branch, 99% of contributions should go there. That way people could test your code before the next stable release.
You can still send a pull request for release in the following scenarios:

Updating README.
Updating GitHub Actions.
Hotfixing a critical bug.

Project maintainers will test and can change your code before merging.
Write at least somewhat meaningful PR descriptions. There's no "right" way to do it, but the following may help with outlining a general structure:

What is the reason for a change?
What did you do to achieve this?
How would a reviewer test the change?

Mind the license. Your contributions will be licensed under the GNU Affero General Public License. If you don't know what that implies, consult your lawyer.
