 - [X] Be able to start a VNC server with OBS, MPV, and Firefox, connect to it, and stream
 - [X] Have another session with the sound isolated
-- [ ] Share the window instead of the desktop?
 - [X] Split the audio so that we can join the Q&A room before the MPV ends - handled by automatic scene switcher detecting mpv
 - [X] Control MPV from the commandline: track-mpv appears in the correct display, and it can also be controlled via the socket like this:
     echo '{ "command": ["loadfile", "test2.webm"] }' | socat - ~/mpv-socket-emacsconf-dev

+*** Set up connection to the track
 
-1. Copy the vnc password file
-   - scp emacsconf-gen@res:~/.vnc/passwd vnc-passwd-gen
-   - scp emacsconf-dev@res:~/.vnc/passwd vnc-passwd-dev
-1. Start up the VNC server if it's not already running
-   - Gen: ssh emacsconf-gen@res.emacsconf.org -L 5905:127.0.0.1:5905 -L 6005:127.0.0.1:6005  "~/bin/track-vnc; sleep infinity" 
-   - Dev: ssh emacsconf-dev@res.emacsconf.org -L 5906:127.0.0.1:5906 -L 6006:127.0.0.1:6006 "~/bin/track-vnc; sleep infinity" 
-2. Connect via VNC viewer to the appropriate forwarded port from your laptop
-     - Gen: xvncviewer 127.0.0.1:5905 -shared -geometry 1280x720 -passwd vnc-passwd-gen
-     - Dev: xvncviewer 127.0.0.1:5906 -shared -geometry 1280x720 -passwd vnc-passwd-dev
-3. Load something with audio in Firefox, and start playing it.
-4. Use pavucontrol to make sure the Firefox process is going into the $track-qa sink.
+1. Set up your local environment
+   
+   gen: export TRACK=gen; export TRACK_PORT=5905
+   dev: export TRACK=dev; export TRACK_PORT=5906
+   
+2. Copy the vnc password file
+   
+   scp emacsconf-$TRACK@res:~/.vnc/passwd vnc-passwd-$TRACK
+   
+3. Start up the VNC server if it's not already running
+   
+   ssh emacsconf-$TRACK@res.emacsconf.org -L $TRACK_PORT:127.0.0.1:$TRACK_PORT "~/bin/track-vnc; sleep infinity"
+   
+4. Connect via VNC viewer to the appropriate forwarded port from your laptop
+   
+   xvncviewer 127.0.0.1:$TRACK_PORT -shared -geometry 1280x720 -passwd vnc-passwd-$TRACK
+
+5. Set up a viewer so that you can monitor the stream
+
+   mpv https://live0.emacsconf.org/emacsconf/$TRACK.webm
+   
+*** Connect to the conf file on res.emacsconf.org
 
-To play an MPV file, ssh to the appropriate account and:
+ssh orga@res.emacsconf.org
+emacsclient -a -c -nw
 
-~/bin/track-mpv files
+*** Play a talk
 
-To change the displayed text, echo text to ~/url.txt, ~/news.txt, or ~/bottom.txt like this:
+Shortcuts for navigating to a talk
+- C-c e a a :: agenda
+- C-c e a g :: gen agenda
+- C-c e a d :: dev agenda
+- C-c e t :: emacsconf-go-to-talk
 
-ssh emacsconf-dev@res.emacsconf.org "echo emacsconf.org/2021/talks/project > ~/url.txt"
+From the agenda, you can use ~C-c C-t~ to set the talk status:
 
-or use ~emacsconf-stream-set-talk-info~ or ~emacsconf-stream-write-news~,
-or use the TODO state change hook set up with ~emacsconf-add-org-after-todo-state-change-hook~.
+| m (mpv) | PLAYING  | emacsconf-stream-play-video, emacsconf-stream-set-talk-info |
+| q       | CLOSED_Q |                                                             |
+| o       | OPEN_Q   | update the BBB redirect URLs to let people into the room    |
 
-To kill the VNC server:
+If the video doesn't play automatically when the talk changes to PLAYING, you can play it manually with:
+
+#+begin_src sh :eval no 
+ssh emacsconf-$TRACK@res.emacsconf.org
+cd /data/emacsconf/2022/stream
+~/bin/track-mpv file
+#+end_src
+
+*** Do Q&A
+
+From the emacsclient on orga@res.emacsconf.org, you can open various talk-related things:
+- emacsconf-stream-open-pad 
+- emacsconf-stream-join-qa 
+- emacsconf-stream-join-chat
+
+Alternatively, you can switch to the VNC viewer and use the links in
+file:///data/emacsconf/2022/index-gen.html or
+file:///data/emacsconf/2022/index-dev.html .
+
+i3 cheat sheet:
+
+- Alt-e toggles horizontal/vertical split
+- Alt-f toggles full-screen
+- Alt-w switches to tabbed view
+- Alt-1 switches to workspace 1, Alt-2 switches to workspace 2
+- Alt-Shift-2 moves things to workspace 2
+- Alt-Shift-Left moves the current window to the left
+- Alt-Shift-Right moves the current window to the right
+- Alt-Enter creates a terminal
+
+For Q&A, you may want to have the Etherpad on the left, the BBB Q&A or
+IRC chat on the right, and the terminal and OBS windows on
+workspace 2.
+
+*** Other tasks as needed
+
+**** Display emergency news / announcements
+
+M-x emacsconf-stream-broadcast  to send a message to both streams
+or M-x emacsconf-stream-set-news to send a message to one stream.
+
+If that doesn't work, edit the news file directly with:
+~ssh emacsconf-$TRACK@res.emacsconf.org > ~/news.txt~
+
+If that doesn't work, use the VNC session to switch to an Emacs window
+and type your message in.
+**** Kill the VNC server:
 
 ssh emacsconf-gen@res.emacsconf.org "vncserver -kill"
 ssh emacsconf-dev@res.emacsconf.org "vncserver -kill"
 
 | ~/bin/track-obs | start OBS with the track's profile and scene collection |
 | ~/bin/track-mpv file.webm | play the file using the track's sink                    |

 There are sockets in the home directory for MPV control if you want to keep that process.

-watch at https://live.emacsconf.org/2022/watch/dev/ or https://live.emacsconf.org/2022/watch/gen/
