Reading Reference Docs
Reference documentation is:
- Information-oriented - Focuses on describing what exists
- Accurate - Every detail matters, kept up-to-date with code
- Complete - Covers all features, even obscure ones
- Structured - Organized for lookup, not linear reading
Don’t read reference docs cover-to-cover. Instead:
- Look up what you need when you need it
- Verify assumptions about how things work
- Discover features you didn’t know existed
- Confirm exact method signatures or parameter types
Need Context?
Reference docs tell you what and how, but not why:
- For why something works a certain way → See Explanation
- For how to use something in practice → See How-To Guides
- For learning from scratch → See Tutorials
