Documentation?

Pardon me for my ignorance, but I cannot figure out how to do anything with this module. I am assuming that under edit content types I should be able to set a point value for a particular node and then it would add points to the user who posted that node. But I don't see any options after enabling this module.... Then I thought it would be rules based and I see how you can have points awarded within rules - however, I saw a question that appeared to imply that you can use rules to add userpoints to a user when they publish a node without this module --- so I'm not even sure this module is necessary...

Could someone please tell me what this module enables and just a general tip on how to use it?
