 ====== Build your own SteamOS ======
-FIXME
+===== Launch =====
+For best results, launch with Gamescope, so apps can launch inside of Steam. You may want to tweak the command line options depending of your setup.
+==== Important gamescope flags ====
+^Name^Description^
+|-e|Enable Steam integration|
+|%%--%%backend|Select the backend (usually drm, wayland, sdl or headless)|
+|%%--%%expose-wayland|Important for launching native Wayland clients|
+|-f|Fullscreen|
+|-g|Grab the keyboard|
+|-W, -H|Window width and height|
+|%%--%%help|Check out the rest of the options|
+==== Launch from a display manager ====
+<code ini /usr/share/wayland-sessions/steam-big-picture.desktop>
+[Desktop Entry]
+Name=Steam Big Picture Mode
+Comment=Start Steam in Big Picture Mode
+Exec=/usr/bin/gamescope -e --expose-wayland --backend wayland --prefer-vk-device --disable-layers -- env WLR_RENDERER_ALLOW_SOFTWARE=1 steam -tenfoot -steamdeck
+Type=Application
+</code>
+You can use ''drm'' or ''wayland'' for the backend option. Then you can configure SDDM to autostart Steam:
+<code ini /etc/sddm.conf.d/autologin.conf>
+[Autologin]
+User=yuki
+Session=steam-big-picture
+</code>
+==== Launch from desktop ====
+Works better if the above doesn't work. Also, lets you easily access the desktop without having to quit Steam. Start a desktop session (such as KDE), create an icon with this desktop file, add it to ''~/.local/share/applications/'', and link it in ''~/.config/autostart/'':
+<code ini ~/.local/share/applications/steam-big-picture.desktop>
+[Desktop Entry]
+Name=Steam Big Picture Mode
+Comment=Start Steam in Big Picture Mode
+Exec=/usr/bin/env WLR_RENDERER_ALLOW_SOFTWARE=1 gamescope -e -W 1920 -H 1080 -f -g --expose-wayland --backend sdl -- /usr/bin/steam -tenfoot -steamdeck
+Type=Application
+Icon=steam
+</code>
+You can use ''sdl'' or ''wayland'' for the backend option. Don't forget SDDM's autologin:
+<code ini /etc/sddm.conf.d/autologin.conf>
