 # Remote Development
 
-Remote Development is in the early stages of development. If you'd like to try it please email [alpha@zed.dev](mailto:alpha@zed.dev).
-
 Remote Development allows you to code at the speed of thought, even when your codebase is not on your local machine. You use Zed locally so the UI is immediately responsive, but offload heavy computation to the development server so that you can work effectively.
 
+> **Note:** Remoting is still "alpha". We have several changes we would like to make before it is fully released.
+
 ## Overview
 
 Remote development requires running two instances of Zed. A headless instance on the remote machine, and the editor interface on your local computer. All configuration is done on your local computer.
 
-Currently the two instances connect via Zed's servers, but we intend to build peer to peer communication in the future.
+Currently the two instances connect via Zed's servers, but we intend to build peer to peer communication before the feature is fully released.
 
 ## Setup
 
-> **Note:** You must be in the alpha program to see this UI. The instructions will likely change as the feature gets closer to launch.

 1. Download and install the latest [Zed Preview](https://zed.dev/releases/preview).

 ## Known Limitations
 
 - You can't use the Terminal or Tasks if you choose "Manual Connection"
-- You can't yet open additional files on the machine in the current project.
 - You can't run `zed` in headless mode and in GUI mode at the same time on the same machine.
+- You can't open files from the remote Terminal by typing the `zed` command.
