+### Meaningful Lines Filtering
+
+By default, Git Velocity filters out non-meaningful code changes when scoring line additions and deletions. This provides a more accurate measure of actual code contributions.
+
+**What's filtered out:**
+- **Comments**: Single-line (`//`, `#`, `--`), block (`/* */`, `<!-- -->`), docstrings (`"""`, `'''`)
+- **Whitespace**: Empty lines, whitespace-only lines
+- **Documentation files**: `.md`, `.rst`, `.txt`, `README`, `CHANGELOG`, `LICENSE`, files in `docs/` directories
+
+**Supported comment styles:**
+- C-style: `//`, `/* */`, `*` (block continuation)
+- Python/Shell: `#`, `"""`, `'''`
+- SQL/Lua/Haskell: `--`
+- Assembly/Lisp/INI: `;`
+- VB: `'`
+- HTML/XML: `<!-- -->`
+
+To disable this filtering and score raw line counts:
+
+```yaml
+scoring:
+  points:
+    use_meaningful_lines: false  # Score all lines including comments/whitespace
+```
