There are quite some steps involved. But they are less than it looks like.
Step 1: Create the database
Step 2: Set the ACL
Since I want anybody to be able to use this little gem, I set default access to Author. Please --> In your environment follow best practices and set it to -No Access- and have an appropriate access group... but that is what the Administrator will do for you anyway. Just keep in mind to create the [Debug] role (You might not understand it but you liked the idea in that SnTT post).
