+# Terminal app
+## Graphical environment (Wayland, VNC)
+By installing Wayland compositor and VNC backend, you can enable graphical environment.
+One of the options is `sway`, `wayvnc` and `xwayland`(if necessary).
+
+```
+sudo apt install sway wayvnc xwayland
+WLR_BACKENDS=headless WLR_LIBINPUT_NO_DEVICES=1 sway
+WAYLAND_DISPLAY=wayland-1 wayvnc 0.0.0.0 # or use port forwarding
+```
+
+And then, connect to 192.168.0.2:5900(or localhost:5900) with arbitrary VNC client.
+Or, `novnc`(https://github.com/novnc/noVNC/releases). For `novnc` you need to install
+`novnc`, and run `<novnc_path>/utils/novnc_proxy`, and then connect to `http://192.168.0.2:6080/vnc.html`
+(or `localhost:6080` if port forwarding is enabled.)
+
+`weston` with VNC backend might be another option, but it isn't available in
+Debian package repository for bookworm.
