It is actually very very very very easy.
But, before you start, try it out on your local machine. Play with it for a bit, then upload it to your production machine.
Basic steps:
1) Unzip to local folder
2) Create SQL database
3) If using access, rename MDB as in the readme - look for the providers in the file listed in the readme
4) Run local application folder
5) Change password
If you read the readme, and look into where you need to set the
provider (database), and follow those basic steps, you should be fine.
If you have a specific problem, then post back. All of your questions are already answered in the readme and the docs.
Also, if you can tell us what kind of background you have, and what you
know, then we can give you better instructions for where you are at.
e.g. total beginner (ground zero and need specific code to cut and
paste), beginner, intermediate, etc...
It is very easy. Takes about 5 min to download and get running. But it took me longer than that the first couple times
