+## Rendering Backends
+
+Morph supports two rendering backends. Choose the one that best fits your needs:
+
+| Backend | Package | Pros |
+|---------|---------|------|
+| **SkiaSharp** | `Morph.Skia` | Mature, includes SVG support |
+| **ImageSharp** | `Morph.ImageSharp` | Fully managed (no native dependencies) |
+
+Both backends expose the same API via `WordRender.Skia.DocumentConverter` and `WordRender.ImageSharp.DocumentConverter`.
+
+
 ## Usage
 
+The examples below use the SkiaSharp backend. To use ImageSharp instead, replace `WordRender.Skia.DocumentConverter` with `WordRender.ImageSharp.DocumentConverter`.
