docs-creating-by-example-tutorials

By-example programming tutorials use a code-first structure with strict annotation density (1.0-2.25 comments per code line) and self-contained runnable examples to help experienced developers learn new languages rapidly without lengthy narrative explanations.

The best way to structure code annotations is to maintain an annotation density of 1.0 to 2.25 comments per code line per example, ensuring maximum educational value without overwhelming the experienced developer reading the tutorial.

The five-part example structure works by enforcing consistency and clarity across all code examples in developer onboarding material, combining self-contained runnable code blocks with multi-block comparisons of alternative approaches to achieve comprehensive language coverage.

Yes, you can include accessible Mermaid diagrams to explain complex concepts in programming tutorials, ensuring the visual aids meet accessibility requirements while helping experienced developers grasp difficult language features quickly.

Yes, this tutorial creation approach enforces annotation density standards and a five-part example structure to achieve 95% core language coverage, ensuring professional programmers get up to speed quickly with comprehensive reference documentation.

You should not use code-first tutorials for educational content targeting beginners, as this approach prioritizes working annotated examples and multi-block comparisons over the lengthy narrative explanations needed by novice programmers.
