I downloaded phpBB-2.0.12-files.zip and extracted the 2.0.11_to_2.0.12 directory. So I have these following directories:
2.0.11_to_2.0.12
cache
contrib
docs
install
I was under the impression that all I had to do was upload and overwrite 2.0.11_to_2.0.12 (keeping in mind that any changes I have made will have to be made again if they are overwriten) until I could not run install/update_to_latest.php. Was I supposed to upload all the directories (cache, contrib, docs, and install)?
I figured I was, so I did! And then I ran install/update_to_latest.php which gave me this message:

Please make sure you have updated your board files too, this file is only updating your database.
You should now visit the General Configuration settings page in the Administration Panel and check the General Configuration of the board. If you updated from versions prior to RC-3 you must update some entries. If you do not do this emails sent from the board will contain incorrect information. Don't forget to delete this file!
Then, I went to my Administration Panel and it informed me to delete install and contrib, so I did.
So, did I do everything right?
You can double-check the version number in the overall footer in the admin panel.
