+- Linux: `watch-together-<version>-linux-x64.tar.gz`. Extract, run

+appears in the strip at the top of the window and opens the update card. "Update and restart" downloads,

-`watch_together --upgrade` or `update.sh` (shipped in the tarball). A
+`./watch-together-server --upgrade` (no display needed, so it works on a
+server box too), `watch_together --upgrade`, or the shipped `update.sh` /

+server; restart whichever is running to use the new version. A
 release with a newer protocol is a required update: everyone on a server
 must run the same protocol version, and a mismatch is refused with a message
 telling you to update.
 
+## Getting started
+
+Three ways in, all at the top of the Library when you are not in a server.
+None of them needs Jellyfin or an account.
+
+- **Join a friend** (most people): your friend sends you an address and,
+  maybe, a password. See [Join](#join).
+- **Host**: you have the video and friends watch it with you. See
+  [Host from the app](#host-from-the-app).
+- **Watch solo**: just play something from the Library. It plays for you
+  alone, with everything a server has (Jellyfin progress, next episode,
+  skip buttons); nothing is reachable from outside this computer. Invite
+  friends in the strip turns it into a hosted server (the Host card's port
+  and password) and the video carries on from where it was; Stop ends it.
+
+## The window
+
+One window. Along the top, the strip: your avatar (click it for your
+profile: name, picture with a crop editor, colour, and links to the
+settings), the Library / Schedule / Settings tabs, and the party. Offline
+the party side has Join a friend and Host; watching solo it says Solo,
+with Invite friends and Stop; in a server it shows everyone's avatar
+with a ring for their state (green ready, amber buffering, grey not ready,
+dimmed reconnecting, dimmed with a moon sitting out; a crown on whoever
+hosts, a tower on whoever passes the video on). Click the avatars for the
+member list (force ready, Nudge, Sit out, "Copy invite address"; when you host it lists this computer's
+network addresses with the port, and friends outside your network need
+that port forwarded or a server they can all reach, like a VPS). Beside them the server and "ready n/m", the chat button with unread
+count, and Leave. Empty strip space drags the window.
+
+The player fills the window under the strip. Pick a tab and it shrinks to
+a mini player in a corner: drag it anywhere and it snaps to the nearest
+corner; double-click or ⤢ makes it big again, × sits you out (below) and
+× again closes it; the strip's screen button brings it back. F or
+double-click on the picture goes fullscreen (the strip hides, the party
+shows in a corner while paused, the window buttons sit in the player's top
+bar while its controls are up), Esc leaves it. The controls show the
+show's cover, title and episode top left (guests get the cover too); before
+a video first plays, its banner fills the picture until playback starts.
+One pill above the controls says what playback waits for ("Press Space
+when you're ready", "Waiting for Bob and Mika · 2/3 ready", "Bob is
+loading…") or what went wrong, with Retry or Cancel when it helps. Chat and activity open in a panel on the right (chat button or
+Tab), ready to type; it shows messages, and its "Activity" toggle adds
+joins, ready, seeks and the like between them. Joins, leaves, chat and
+other news also pop up bottom left with the person's avatar; click a message to open the chat. Unread chat
+shows as a count on the chat buttons and, in fullscreen with the controls
+hidden, as a small chip top right.
+
+Your name and picture change for everyone in the server right away; the
+colour is yours only.
+
+**Sitting out.** Step away without leaving: Sit out (your profile, your
+row in the member list, or × on the mini player) unloads the video on your
+end, and nobody waits for you any more; you stay in chat. Anyone can sit
+anyone out, the host too ("Alice sat you out" tells you who). The player
+then shows the cover, title and where the others are; Join back (or Space)
+loads the video there and readies you. Settings → Party & network → "When idle,
+sit out instead of just unready" does it after 10 idle minutes.
+
+**Nudge.** Nudge in the member list pokes someone, sitting out or not:
+only they hear it (a sound, a pop-up, and the taskbar entry asks for
+attention when the window is in the background).

 ## Host from the app
 
-Home, Host tab. Pick what to watch (optional): Jellyfin (browse your linked
-servers, see below), Link (paste an http(s) URL; Ctrl+V outside a field
-pastes it in) or File (path or Browse). In the column beside it set a port and an optional password (blank =
-anyone can join), then Host. Your name and avatar come from your profile
-(the chip at the top left). The app starts a
-server inside itself and joins it; you are the host and nobody can kick you.
-Leaving or closing the app stops the server. Friends need to reach your machine: open
-the TCP port on your router (or use a LAN or VPN address). Friends open nothing.

+the TCP port on your router (or use a LAN or VPN address). Friends open
+nothing. Ports you hosted on before are one click away in the Host card.

+## Library
+
+What to watch, from three sources (the switch at the top). Drop a video,
+a folder or a link anywhere on the window, or press Ctrl+V outside a
+text field, and a small card asks how to open it (put it up, add the
+folder to Files, or fill Link).
+
+- **Jellyfin**: your linked servers (see below); with none linked it
+  points to Files and Link and offers Jellyfin as optional. Library chips beside the
+  switch, then one **Continue** row (what you were watching and what comes
+  next, one card per series, the one you watched most recently first;
+  series not touched for two months drop out) and **Latest in** each
+  library (one card per series: "S1E1" or "3 new"; Show all opens the
+  library newest first). Re-uploads (added long after they aired) are
+  hidden from Latest; the row's ⋮ menu turns that off. Search (/), library
+  grids (sort, unwatched, favourites) and series pages sit behind them.
+  Click a card to select it: its
+  details open on the right with "Put it up · S1E3", mark watched /
+  unwatched, remove from Continue and the episode list (click an episode
+  to choose it). Double-click a card or an episode to put it up at once.
+- **Link**: paste an http(s) link: a video file, or a web page with a
+  video (YouTube, X, and whatever else yt-dlp knows). The preview shows
+  what it is (a page's title, uploader, length and thumbnail, else the
+  file name); in a server, pick how the
+  others get it (everyone fetches it, the server fetches it, or through
+  you). Your last 12 links are listed under it.
+- **Files**: video folders you add on this computer, grouped by series
+  (click a series to list its episodes), or any file through Browse. The others stream it from you.
+
+Put it up and the player opens. Not in a server, the buttons say Play
+and it plays for you alone ([Watch solo](#getting-started)).
