This guide explains practical ways to generate and maintain cookbook <code>README.md<\/code> files so recipe, attribute, platform, and dependency information stays easy to find.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Originally published on 2015-08-18; fully revised and updated.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why README drift happens in reusable Chef cookbooks<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The original problem statement is still common: teams build reusable cookbooks, add many resources and recipes over time, and documentation falls behind. In older Chef terminology this often appeared as an &#8220;explosion of LWRPs&#8221;; regardless of resource style, the core issue is the same: code changes faster than docs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What a useful cookbook README should cover<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A practical cookbook README should help another engineer understand what the cookbook does, where it runs, and what it depends on.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Available recipes and their purpose<\/li><li>Key attributes and expected values<\/li><li>Supported platforms<\/li><li>Cookbook dependencies and requirements<\/li><li>Usage examples for common scenarios<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">README generation options<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The original post presents two patterns: create a README correctly at scaffold time, or generate documentation automatically with Knife plugins.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Approach<\/th><th>How it works<\/th><th>Best for<\/th><th>Trade-offs<\/th><\/tr><\/thead><tbody><tr><td>Knife scaffold with Markdown README<\/td><td>Create a new cookbook with a Markdown README from day one.<\/td><td>Standardizing new cookbook layout<\/td><td>Only gives an initial file;
