Some advice for the post-processing section

[ldang]

We shoudl add this to the post-processing section of the manual

Via Robert Perrett:

"I will talk about my editing process, at first when I started, I did a lot of notes where the start and end points could be. I realized that later that it bogged me down. It is better to do a rough edit and the points can be adjusted. Sometimes I will put comments in for clarification, but it is better to put the points in, and move on and add comments later."
