+## Sunshine and Moonlight
+
+<https://docs.lizardbyte.dev/projects/sunshine/en/latest/>
+
+Sunshine is desktop streaming service that leverages hardware encoding to provide near-zero latency
+network streaming to any device that can run moonlight.
+
+### Install Sunshine
+
+<https://docs.lizardbyte.dev/projects/sunshine/en/latest/about/setup.html#install>
+
+I used the Archlinux pkg. Follow the instructions (including the autostart instructions).
+
+### Install Moonlight
+
+<https://github.com/moonlight-stream/moonlight-qt/releases>
+
+I just used the flatpak installer.
+
+### Configuration
+
+Sunshine doesn't need a ton of config. For streaming to devices like the steam deck
+and my computer I would recommend adding a new application that uses the `display_scale.py`
+script to set the resolution of the host before connecting.
+
+1. Copy `display_scale.py` to your host
+2. Create a new application
+3. Add command: `/home/ducoterra/display_scale.py 1920x1080 1`
+4. Optionally add undo command: `/home/ducoterra/display_scale.py 3840x2160 1`
+5. Save and connect!
