HOW TO SETUP A WIRELESS REPEATER WITH MIKROTIK RADIO

hello,
i have the target to setup a wireless repeater for a school. I have the 1sst AP already running with hotspot, but i want a situation where i want to extend the wireless link to another building which people in that area cannot connect to the router/hotspot without getting another AP setup for them. But i know mikrotik can do such, that is why i need to use a reapter so that they can still use the same hotspot for authentication and billing.

Thanks and your detail step-by-step will be appreciated.
