W/O seeing your specific situation, it would be hard to say what needs to be done. The most anyone can do, here, is give general advice on how to build standard steps. Also, there are code issues. (hand railing issue(s), height of step, etc., etc..)
There are other books I'm sure. Try the on-line book stores like Amazon.com, FatBrain, Barnes&Nobels, etc., etc..
