 ## What are your recommendations for WebAR?
 
-For a good experience with WebAR:
-
-* Don't move the camera nor the target image too quickly. This produces motion blur.
-* The target image should appear clearly in the video.
-* The physical environment should be properly illuminated.
-* If you're scanning the image on a screen, make sure to adjust the brightness. If the screen is too bright (too dark), it will cause overexposure (underexposure) in the video and tracking difficulties - details of the images will be lost. Screen reflections are also undesirable.
-* If you print the image, avoid shiny materials (e.g., glossy paper). They may generate artifacts in the image and interfere with the tracking. Prefer non-reflective materials.
-* Avoid low-quality cameras. Cameras of common smartphones are okay.
+Refer to the [recommendations](./recommendations.md).
