Why Use This Plugin?

Problem

Out-of-the-box MkDocs generates sitemaps and search indexes with build dates, not actual revision dates. This is suboptimal for:

• SEO: Search engines prefer pages with accurate <lastmod> timestamps
• User experience: Users want to know when docs were actually updated
• Search results: Search indexes don't show update information

Solution

This plugin:

1. Extracts the actual last commit date for each page from git history
2. Injects it into sitemap.xml for SEO benefits
3. Formats and adds it to the search index so users see up-to-date info
4. Works independently with flexible date formatting

Requirements

• MkDocs >= 1.0
• Python >= 3.9

Supports
