   * Any projector will do, but any projector with a native resolution of less than 1080p will only be good for projecting shapes & very large text.
-  * Ultra-short-throw projectors like the Samsung The Premiere are expensive but can be really bright and may allow you to avoid overhead mounting.
+  * Ultra-short-throw projectors like the Samsung The Premiere are expensive but can be really bright and may allow you to avoid overhead mounting. It may be difficult to calibrate an ultra-short-throw projector (because it's hard to tilt the calibration board and the optics are really distorted)

-  * Any 720p, 1080p, or 4K webcam may work, but we recommend you get a webcam that has the ability to **set manual exposure** (including any of the below). You'll also have a better experience if the webcam can at least do 60fps at 720p.
+  * Any 720p, 1080p, or 4K webcam may work, but we recommend you get a webcam that has the ability to **set manual exposure** (including any of the below). (This is so that the camera image doesn't get washed out by light from the projector during calibration.)
+    * You'll also have a better experience if the webcam can do 60fps at whatever resolution you have set.
     * We would recommend a [[https://www.amazon.com/Microphone-NexiGo-N980P-Reduction-Wide-Angle/dp/B08DHPBP65|NexiGo N980P]] (1080p, 60Hz) or Logitech BRIO 4K (4K, 60Hz).
       * A Logitech C920 series 1080p webcam is often used & is easy to find & affordable, but the [[https://www.bestbuy.com/site/logitech-c922-pro-stream-1080-webcam-for-hd-video-streaming-black/5579380.p?skuId=5579380|Logitech C922]] is probably a better option, because it can do 720p60; the C920 can only do 720p30.
       * (We used to use a Microsoft Azure Kinect, but it can only do 30Hz.)
+    * Hang your webcam as close to the table (projection surface) as possible. You want the tags to be as big in the webcam image as possible to help detection stability. (If ceiling mounting, you will probably find that your webcam should be much lower than your projector.)

 ==== Support ====
-Note: it's very not-turnkey right now; you'll definitely run into bugs and issues. We plan to do a more comprehensive release and announcement in 2024, including more examples and explanations, but there's a lot of work to do before then.
