+### Markdown Formatting
+
+This repository uses a Rust-based Markdown formatter (dprint) to ensure
+consistent documentation formatting. When submitting pull requests that include
+Markdown files, the formatter will automatically check for formatting issues.
+
+To run the formatter locally:
+
+1. Install dprint:
+   ```bash
+   cargo install dprint
+   ```
+
+2. Check for formatting issues:
+   ```bash
+   dprint check "**/*.md"
+   ```
+
+3. Automatically format all Markdown files:
+   ```bash
+   dprint fmt "**/*.md"
+   ```
+
+The formatter enforces a maximum line length of 80 characters and consistent
+formatting across all Markdown files.
