Guidelines for Developing Tutorials
- Clearly define the problem in the title
- Expand on the title in the first paragraph so people know if they are reading the right thing
- Use a real world example of content as a starting point
- Incrementally annotate it in the SIMPLEST WAY POSSIBLE that addresses the problem statement
- Use fragments for examples - complete documents are intimidating and hard to read
- Never Never Never mention a triple nor a Bnode!
