 Do you want to set up your own Folk system?
-==== Getting access to the system ====
+**Note: Folk is in a pre-alpha state and isn't yet well-documented or well-exampled.**
-We've been adding folks to our private GitHub repository and Discord -- you'll want to sign up for [[https://github.com/sponsors/FolkComputer|our GitHub Sponsors]], which covers our costs for that (for example, until we open-source the system, we have to pay GitHub monthly for each seat we add to the repo).
+**We're making Folk's source code & instructions free and available to the public, in case you're already excited about trying it, but we haven't formally announced it or made it ready for public use. We make no guarantee of support, of usability, or of continuing backward compatibility. Try at your own risk!**
+==== Software requirements ====
+Folk is open-source software, available to the public under the Apache 2.0 license.
+**See [[https://github.com/FolkComputer/folk?tab=readme-ov-file#folk|the README on GitHub]] for software instructions.**
 ==== Hardware requirements ====
-From scratch, we would estimate somewhere between $50-200 per square foot that you want to cover, depending on decisions like what resolution and framerate you want. You may already have a projector and/or webcam and/or computer -- we would recommend at least getting a dedicated computer and not using your laptop, though.

   * 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. 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)
 == Camera ==
-  * Any 720p or 1080p webcam will do.
+  * 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.

+    * 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.)
