How to connect two 433UAH+R52 wirelessly

I don´t know how to configure my two 433UAH routers, with 2 R52 boards installed into each, so they talk to each other (internet connection hooked to 1 rt, providing wifi coverage as well, and the other rt talking with the first one and also providing wifi signal)

I thank you in advance!

Checked the wiki???
