 ## Setup
 
+It is recommended to have another reverse proxy above (for example [Caddy](https://caddyserver.com/), nginx, HAProxy) to handle HTTPs or similar.
+
+go-away for now only accepts plaintext connections, although it can take _HTTP/2_ / _h2c_ connections if desired over the same port.
+
+### Binary / Go
+
+Requires Go 1.22+. Builds statically without CGo
+
+```shell
+git clone https://git.gammaspectra.live/git/go-away.git && cd go-away
