 Additionally it's worth noting that while you can pass a password on the command line `zed ssh://user:password@host/~`, we do not support writing a password to your settings file. If you're connecting repeatedly to the same host, you should configure key-based authentication.
 
+## Remote Development on Windows (SSH)
+
+Zed on Windows supports SSH remoting and will prompt for credentials when needed.
+
+If you encounter authentication issues, confirm that your SSH key agent is running (e.g., ssh-agent or your Git client's agent) and that ssh.exe is on PATH.
+
+### Troubleshooting SSH on Windows
+
+When prompted for credentials, use the graphical askpass dialog. If it doesn't appear, check for credential manager conflicts and that GUI prompts aren't blocked by your terminal.
+
+## WSL Support
+
+Zed supports opening folders inside of WSL natively on Windows.
+
+### Opening a local folder in WSL
+
+To open a local folder inside a WSL container, use the `projects: open in wsl` action and select the folder you want to open. You will be presented with a list of available WSL distributions to open the folder in.
+
+### Opening a folder already in WSL
+
+To open a folder that's already located inside of a WSL container, use the `projects: open wsl` action and select the WSL distribution. The distribution will be added to the `Remote Projects` window where you will be able to open the folder.

 ## Port forwarding
 
 If you'd like to be able to connect to ports on your remote server from your local machine, you can configure port forwarding in your settings file. This is particularly useful for developing websites so you can load the site in your browser while working.
