This document assumes you have read Development.md.
Wikijump has a fairly extensive scope and has lots of areas for people to contribute. Whether it's a small typofix or work on a potential new feature, there's always room for community contributions. If appropriate, a team member can make a JIRA issue for it.
It is important that you join the Wikijump Discord so you can discuss and coordinate with the Wikijump team. You can get an invitation by asking in #site11.
Once you've implemented the changes, create a PR and request reviews from 1-3 relevant people. See CODEOWNERS to get an idea of who works on which parts of the repository. It'll be reviewed and merged if ready.
All changes should be merged against develop, which automatically deploys to wikijump.dev. In longer cycles, we take accrued changes in develop and produce a squash commit to prod, which deploys to wikijump.com (the production environment). This way can utilize continuous deployment for development but also keep production stable. (See CI.md for more information)
