Documentation should follow consistent formatting and structural patterns to maximize readability and maintainability. Key guidelines: 1. Keep line lengths to 80 characters maximum 2. Place all document links at the bottom of the file and use in-doc references 3. Document default behaviors before introducing exceptions 4. Use proper spacing and indentation for examples and code blocks Example of proper documentation formatting: ```markdown # Feature Name Default behavior description first, followed by any exceptions or special cases. ## Usage ```js // Code example with proper indentation const example = require('node:example'); example.doSomething(); ``` ## Options * `option1` {string} Description fits within 80 chars, continues on next line with proper indentation. * `option2` {Object} Another option description. [link-reference]: #section-name ``` This format ensures consistency across documentation and makes it easier for users to find and understand information.
