Updated project documentation for MD-CMS, including changes to the CLI tool description, repository layout, and version markers. Adjusted folder names and clarified local preview instructions.
Documents the two-part architecture (mdcms.py CLI + index.html renderer), menu option reference, content structure, frontmatter fields, category system, nav.yml behaviour, dynamic post tags, known limitations, and key implementation quirks (non-general YAML parsers, category code validation). https://claude.ai/code/session_018gathVoTZhBFDJVp1mVaTc
