 ### Set Restricted View Settings
 
-Both routes take String parameter which sets restricted view size in one of two formats: as an image dimensions or a 
-percentage. The dimensions pattern looks like: `!X,X`, where X is the number representing scaled image dimensions in
-a square, so that the width and height of the returned image are not greater than the requested value.
-Example: `!512,512` means the image's bigger side will be set to 512 pixels, setting the other side respectively to
-image aspect ratio. The percentage pattern looks like: `pct:X`, where X is the number between 1-100 representing the
-percentage the image will be scaled to. Example: `pct:1` means the image will be scaled to 1% of the original image
-size.
+Set how all still image resources of a projects should be displayed when viewed as restricted. 
+This can be either a size restriction or a watermark. 
+
+For that, we support two of the (IIIF size)[https://iiif.io/api/image/3.0/#42-size] forms:
+
+  * `!d,d` The returned image is scaled so that the width and height of the returned image are not greater than d, while maintaining the aspect ratio.
+  * `pct:n` The width and height of the returned image is scaled to n percent of the width and height of the extracted region. 1<= n <= 100.
+
+
+If the watermark is set to `true`, the returned image will be watermarked, otherwise the default size `!128,128` is set.
+It is only possible to set either the size or the watermark, not both at the same time.
