+### FRP for Home Assistant
+<a href="https://github.com/fatedier/frp">FRP</a> (Fast Reverse Proxy) allows you to quickly setup Remote Access for your Home Assistant instance, if you already have a public VPS with a public IPv4. This is helpful because many home internet connections nowadays, with things like DS-Lite, no longer have their own public IPv4 address, making port forwarding a nightmare.
+
+To setup a FRP Server, please refer to the original projects documentation. This Readme is just for setting up the Add-on to an existing FRP server
