How do you edit an automator service

New to automator - How do I edit a previously created automator service?

I just created a service (Finder context menu) and it works fine, but I don't know where the code is stored or how to access it. I'd like to try a tweak.

Is this the right place for such a question?

thanks much,

It's stored in /Users/####/Library/Services/example.workflow

Great, thanks much.
