Don't fall into that trap.. I did. Here is what I learned: 1) There is no complete answer to how to document a project. anyone that tells you otherwise probably doesn't code or support someone else's work. 2) Learning project management takes time and experience. A book won't help.. I have several and all are equally useless. 3) Project management doesn't sound like what you are looking for (like the other person above said, PM is for Middle Management). what you need to do is look at it from the outside. if you had to come in to support someone else's website/database, what would you need to be able to support it successfully? inputs, outputs, timings, schedule jobs, maintenance jobs, etc. Document what those are and how they run. Then create some basic flows to describe how the system integrates together. Being the only IT developer will make the documentation more difficult and you aren't going to get it right the first time (or first dozen times). Just be ready to add or remove information from your documentation as you go. Also, every time you have to research something, create a document that defines what the problem was and how you fixed it.. you or someone that follows you may need it to resolve future problems. And don't trust what I tell you to be true or final. You will find a better way as you go through it.
