+**4. Adding overlays**
 
-ImageKit.io allows you to add [text](https://docs.imagekit.io/features/image-transformations/overlay-using-layers#add-text-over-image) and [image overlay](https://docs.imagekit.io/features/image-transformations/overlay-using-layers#add-images-over-image) dynamically.
+ImageKit.io enables you to apply overlays to [images](https://docs.imagekit.io/features/image-transformations/overlay-using-layers) and [videos](https://docs.imagekit.io/features/video-transformation/overlay) using the raw parameter with the concept of [layers](https://docs.imagekit.io/features/image-transformations/overlay-using-layers#layers). The raw parameter facilitates incorporating transformations directly in the URL. A layer is a distinct type of transformation that allows you to define an asset to serve as an overlay, along with its positioning and additional transformations.
+
+### Text as overlays
+
+You can add any text string over a base video or image using a text layer (l-text).
+
+For example:
+
+```python
+image_url = imagekit.url({
+    "path": "/default-image",
+    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
+    "transformation": [{
+        "height": "300",
+        "width": "400",
+        "raw": "l-text,i-Imagekit,fs-50,l-end"
+    }],
+})
+```
