Overview

Notes for self-education:

• The workshop is divided into days, each day containing several topics.
• For each topic, follow the instruction under chapters "Contents" and "Assignment".
• The "Contents" section instructs what to read and try in practice. It usually contains bullets with instructions what to do for each section of the referenced documentation. Look for the following marks:
  • Read - Read the referenced documentation section, no need to implement it.
  • Demonstrate - Implement the referenced example in your development environment, and test it.
  • Skip - The referenced documentation section is not part of the current workshop topic.
• The "Assignment" section contains a homework assignment. Implement it in you development environment.
• The "Documentation" section is just a list of references.
• Some topics currently have incomplete documentation (see TODO tags in other files).
