How do i? Remove front and rear bumpers?

Hi All,

So i have a project list to do on my mk2.5 1.8 and some of this will include taking the bumbers off.  Any tell me are there any hidden clips etc that i need to be aware of or is it fairly straight forward?  Is there a post anywhere that tells me the sequence of screws brackets i will need to undo/remove?

Many thanks,
