It really is personal preference. If you want to go "PVR" you do have to do some configuration, or you can get going quickly with Xtream-codes add-on with just two entries in the settings, and a "donation-only" setup on the donation checker (that is, no MAC).
There hasn't been much change in how you configure things for the last year or so, so there hasn't been any real need to change the how-to tutorials.
