Starting a Salt Water tank

[THEONE1]

Ok i have a 20 galon fresh water tank with a few fish in it. Today i went to a local pet store and fel in love wiht the look of a salt water tank. My question to you guyz is what do i need to read up on in order to start one up. I dont want any complicated tanks for rithg now. I saw a the store only fish and rocks and thats all i want for right now. Maybe one of you guyz can point me out toward the right direction. Thanx
