+> [!NOTE]

+
+Tailray requires Tailscaled to be up and running. On Linux systems, you can
+check its status with `systemctl status tailscaled`.
+
+After you confirm that Tailscale is running, and that you are authenticated run
+`tailray` from a terminal or consider writing a systemd service for it.
+
+### Overriding Admin Console URL
+
+Tailray will assume `https://login.tailscale.com/admin/machines` to be the Admin
+Console URL by default. You may override this URL by setting `TAILRAY_ADMIN_URL`
+to an URL of your choice.
 
 ## Hacking
 
-Simply run `nix develop` in the project root.
+The recommended way of building Tailray is with the Nix build tool. You may run
+`nix develop` in the repository to enter a devShell with the necessary
+dependencies. Direnv users may also use `direnv allow` to let direnv handle
+their shell environment.
