 ## Migration Guide
 
+### Using Android 9-Patch Files
+
+FlexLove now automatically parses Android 9-patch (*.9.png) files. Simply rename your files to include the `.9.png` extension and remove manual insets:
+
+```lua
+-- Old (manual insets)
+components = {
+  button = {
+    atlas = "themes/space/button.png",
+    insets = { left = 14, top = 14, right = 14, bottom = 14 }
+  }
+}
+
+-- New (auto-parsed from .9.png file)
+components = {
+  button = {
+    atlas = "themes/space/button.9.png"
+    -- insets automatically extracted from 9-patch borders
+  }
+}
+
+-- Manual override still works
+components = {
+  button = {
+    atlas = "themes/space/button.9.png",
+    insets = { left = 20, top = 20, right = 20, bottom = 20 }  -- Overrides auto-parsing
+  }
+}
+```
+
+**9-Patch Format:**
+- Top border (row 0): Horizontal stretch regions (black pixels = stretchable)
+- Left border (column 0): Vertical stretch regions (black pixels = stretchable)
+- Bottom border: Horizontal content padding (optional)
+- Right border: Vertical content padding (optional)
+- Supports multiple non-contiguous stretch regions for complex scaling patterns

 ### From `background` to `backgroundColor`
 
 If you're updating existing code, replace all instances of `background` with `backgroundColor`:
