Unfortunately, I just don't have time to maintain this project anymore. This repository is now archived, but will remain in place for anyone still using it.
I suggest migrating to the Caddy 2 Add-on, which I've been using successfully for several months.
This repository contains just one add-on, an unofficial Caddy add-on.
Add this repository to your Hass.io instance:
https://github.com/korylprince/hassio-caddy
If you have trouble you can follow the official docs.
Then install the "Caddy" add-on.
See the Caddy add-on itself for information on configuring it.
If you have an issue with this plugin, please file an issue.
