Help

I am a new user of free radius, actually I have one Server installed in a Linux red hat operative system computer, but I have no idea how I have to configure the clients and the Server to work together, I want to Protect my wireless network using this radius Server, the access point of the network can use the 802.1x authentication but I am not sure if it can work with the free radius, could somebody share some documentation or knowledge about the fine tuning for the free radius server, thanks in advanced.
