+Dosh can carry VS Code Remote-SSH without replacing VS Code's SSH workflow.
+
+```sh
+dosh vscode setup server
+dosh vscode server /home/me/project
+```

+This writes a managed SSH config entry using:
+
+```sshconfig
+ProxyCommand dosh proxy-stdio server %h %p

 Dosh can also be used as a Rust transport for application protocols that need
