+### Environment variables
+
+- `MW_SCRIPTPATH`: The base URL for API requests for your wiki. For the XIV wiki it's `https://ffxiv.consolegameswiki.com/mediawiki`; other wikis may use paths other than `/mediawiki`, which can be identified in Special:Version as "Script path".
+- `MW_USERNAME` and `MW_PASSWORD`: Account username and [bot password](https://www.mediawiki.org/wiki/Manual:Bot_passwords), respectively
+- `MW_KILLPAGE`: The name of a page that will be checked when running unattended scripts. If this page contains content, the bot will be killed. This allows other editors to kill the bot if it starts misbehaving and you're not watching it.
