How to Add UniqueIdentifier field to an existing table

[minifelt]

Hello,
I have an existing table with several thousand records. I need to add a uniqueidentifier field to the table. Can you give me an idea of what steps to take to do this?
Thank you.

What do you need help with? Do you need help with:

Probably all of the above

My suggestion, without having those questions answered, would be to look into adding an identity column.
