-This repository started as personal notes, and it's growing into short guides.
+This is a list of quickstart guides for Linux programs.
 
 # Purpose
 
 1. Minimal theory, maximum practical.
 2. The statements should go in order of how likely they are to be used: if `git add` has to be used by everyone, then it should go first.
 3. The scripts should get someone up and running in the shortest possible time.
-4. No explanations for the program.  This isn't an introduction, it's a guide for someone who already wants to use it.
+4. No explanations for the program.  This isn't an introduction or advert, it's a guide for someone who already wants to use a program but doesn't know how.
+5. Easy reference.
 
+# What's wrong with everything else?
+
+## Man pages
+
+- Orders items by the alphabet rather than by relevance.
+- Often presumes you know everything except that one program.
+- Often written in the 80's, and it shows.
+- Zero respect for your time.
+
+## tl;dr
+
+- Doesn't have the programs I like.
+- Too short to get you started on many programs.
+- Poor understanding of priority (`git stash` is covered byfore `git commit`).
+
+# History
+
+It started as a few personal notes, and will probably continue to look like that for some time.
