-- To add custom CSS for all users, edit `./custom/instance.css`.

+- To add custom CSS for all users, edit `./custom/assets/instance.css`.
+- To add static assets (such as images for the splash screen), place them in the `./custom/assets/` directory. They'll then be avaliable on `https://yourinstance.tld/static-assets/filename.ext`.
+- To add custom locales, place them in the `./custom/locales/` directory. If you name your custom locale the same as an existing locale, it will overwrite it. If you give it a unique name, it will be added to the list. Also make sure that the first part of the filename matches the locale you're basing it on. (Example: `en-FOO.yml`)
 - To update custom assets without rebuilding, just run `yarn run gulp`.
