How to create and TDE encrypt a sql instance and db?

I'm looking for a step by step how to. Sorry if this is an overly broad question.

Creating a new instance shouldn't be much of a problem. Run the sql install, create a new instance with a new name.

I'm no dba, have zero experience with encryption, so... is TDE applied after the instance is created? Would I backup/restore a db to the new instance before or after applying TDE? Is TDE "applied", and how?

HALP

Thanks,

Scott
