You need to activate the event that will deliver Oak's letter to the guy in the Pokemart.
(By either action replay or going to an event) then after receiving it go to victory road and find the exit that leads to route 224 from there go north to the white rock where you'll meet Prof. Oak the rock will move and a long path will appear, follow it and at the end (it's long, very, very long.) and you will see Shaymin. All you need to do is go up and interact with it like any other legendary Pokemon. It's at level 30 so bring a Pokemon that level or one with the move "False Swipe" witch leaves one Hp left.
