So I've used PunBB on different sites and liked it very much. I've decided that I would like ot use PunBB as my own forum system but a few problems being...

1. I've used freewebs and to my understanding I cannot use PunBB there.
2. I know pretty muc nothing to do with coding or php etc... Is there some step by step post or site that I can read through.
3. What key htings should I learn even before attempting to  install and run PunBB.

Thank you  for any information you may be able to provide me with.
