Contributing

We are always looking for people to help contribute to this wiki!

Feel free to add Tutorials, reference guides, or anything else you might think is needed. After adding a page, please add it to the Sidebar under the relevant category, or add a new category if necessary.

Where possible, we are trying to update old pages and create new pages following the system described here 🔗.

If you want to modify this wiki using git, follow the instructions here 🔗, bundle 🔗 your changes and ping an Everest Team member to get them added.
If you plan on moving or renaming files, please use git filter-repo --path-rename 🔗 to change their paths in history. GitHub wikis cannot handle renamed files. For prominent pages that may be linked to often, keep the original page with a link to the renamed one.
Note that all relative links to other wiki pages should be treated as if all files are in the same folder.

If you are working on a page, add it to the In Progress section of this article.

For any questions, join the celeste Discord 🔗 and ask under #modding_help
