+# Renderers Layer
+
+The `docforge.renderers` package handles the transformation of the internal
+documentation model into physical files formatted for specific documentation
+engines.
+
+## Current Implementations
+
+- **MkDocsRenderer**: Generates Markdown files utilizing the `mkdocstrings`
+  syntax. It automatically handles package/module hierarchy and generates
+  `index.md` files for packages.
+
+## Extending
+
+To add a new renderer, implement the `DocRenderer` protocol defined in
+`docforge.renderers.base`.
