Raspberry Pi 4 WiFi

Hello i'm a noob when it comes to openwrt on raspberry pi.
Can someone ether link me a guide or tell me a how to, so i can get my wifi working on it?
Many thanks

Should work out of the box, I think...

You'd need to boot from the raspbian image first, run rpiconfig, setup the wifi to select country code, and then it should work in OpenWrt as well.
