Hover any key or value to see what it does, its type and the values it takes. Press Ctrl+Space for completions; mistakes are marked as you type. The mise.toml reference has every key. Editing happens in your browser. Copy link puts the config in the page's address so you can share it, which means anyone who opens that link, and the docs server that serves it, receives the config. Leave secrets out of it.

To see what each key of a file on disk does, run mise config explain.
