I've just installed Mercurial on my Mountain Lion Max (10.8) and on my first commit I'm getting the error:

abort: no username supplied (see "hg help config")

I've seen a load of answers which suggest I need to create or copy a file form a certain location and paste it into another location and add my username and email to the document.

If that is the right thing to do:

• Where is the file I need to copy (or what is the file called that I need to create)
• Where do I put that file

• Do I just need to add the following two lines to the file?

  username = Your Name

Thanks guys.
