 this repo holds configuration files for `dotya.ml`-operated
 [`renovate`](https://github.com/renovatebot/renovate)
 [bot](https://git.dotya.ml/renovate-bot).
+
+### usage
+fill (or otherwise provide to the process) desired environment variables and
+run `bin/renovatepls` regularly (ideally with `cron` or using a `systemd`
+timer).
+
+`renovatepls` is just a simple bash script that does just that: sets some env
+vars (might need to modify them, e.g. for using with your own instance of
+Gitea...) and then executes `renovate`.
