I agree with jinky - 'basic' is just about impossible to define.
I only shoot in RAW, so I always have to 'develop' my pictures. There is clearly no 'basic' way to do this unless you say apply the defaults of the conversion software. But then which software? Most use ACR within Elements or Photoshop or Lightroom, but I use DxO and Matthew uses Photoplus. Others will use Paintshop Pro - they'll all produce different results, so which one is 'basic'? If I shoot in jpg for a competition, then what in camera settings are allowed? All cameras are different.
Also, one of the ideas behind the comps is to learn new skills - and that won't happen with editing if we restrict it. The 'darkroom' side of photography is pretty much as important as the capturing side IMHO. In the film days I regarded pressing the shutter as the first step in creating a photograph with hours of honing to follow in the darkroom; from choosing what developer to use, and for how long, to choosing the paper, filters etc, to what to dodge/burn etc under the enlarger.
Only the tools have changed, now it's a computer and screen and not baths of chemicals and an enlarger. But what we're doing is trying to make the best photograph we can with the skills and tools that we have to hand.
And hopefully keep on learning how to do it better
