+## next-multisession
+As requested by a few in the [JetKVM Discord](https://jetkvm.com/discord), this tree also includes a branch that enables
+support for multiple sessions connecting to the JetKVM.
+
+It's a bit of a bodge implementation, but shows the multiple sessions can be handled by the JetKVM.
+
+Every release of jetkvm-next includes jetkvm-next-multisession in a pre-release, the jetkvm-next-multisession branch is based
+off the main jetkvm-next branch, and applies changes to the session handling code.
+
+next-muiltisession does not include any concept of control authority/mutex, so all users connected will have full control
+over the target machine, and you'll be fighting for the cursor with the other user.

 ## Additional Info
 There's a GitHub Action setup to build the JetKVM software whenever this repo has a new release added, it'll take
 a few minutes for the binary to appear on the release once this repo is tagged.
