The Chords in Markdown plugin adds basic support for rendering musical chords within lyrics using a Markdown code block. It leverages the `markdown-it-chords` library to interpret chord notation inside fenced code blocks labeled as `song` or `lyrics`. Users can embed chords inline with lyrics using simple square-bracket notation like `[C]`, and the plugin handles even complex chord symbols or fret positions. This is especially useful for musicians or songwriters who want to document and format chord sheets directly in their notes. The current version is minimal, but offers a clean and readable way to manage chord-annotated lyrics.
