Use Heading Hierarchy
Structure content with proper heading levels (# H1, ## H2, ### H3). This improves accessibility, SEO, and document navigation. Never skip heading levels (don't jump from H2 to H4).
Code Block Language Tags
Specify language after opening code fence (```javascript) for syntax highlighting. This works on GitHub, GitLab, and most Markdown renderers. Supported: javascript, python, java, sql, bash, and 100+ others.
Link Best Practices
Use descriptive link text instead of 'click here'. Good: [View documentation](url). Bad: Click [here](url). This improves accessibility for screen readers and SEO for documentation pages.
Table Formatting
Use GFM tables for structured data. Align columns with pipes (|) and hyphens (-). Add :-- for left align, :--: for center, --: for right. Tables enhance README readability significantly.
Task Lists for READMEs
Use - [ ] for unchecked and - [x] for checked tasks in project READMEs. This creates interactive checkboxes on GitHub, perfect for feature lists, roadmaps, and progress tracking.
