 ## 6. Admin and console
-In-game chat starts with `/`; the server console takes the same commands
-without it.
-- `/players`, `/kick <name>`, `/ban <name>`, `/unban`, `/admin <name>`
-- `/save`, `/backup`, `/time 08:00`, `/weather clear|rain|storm|snow`
-- `/rules` (show) and `/set pvp on` (change at runtime, saved to
-  `server.json`)
-- `/rename <old> <new>`, `/release-name <name>`
-- `/say <message>` (a server message)
+*(Built in M2.6: `chat.gd`, autoload Chat; `rules.gd`.)* In-game chat
+starts with `/`; the server console takes the same commands without it
+(the server reads its terminal when started with `--console`, which
+`server/run_server.sh` does).
+- Anyone: `/help`, `/players`, `/rules`, `/friend <name>`,
+  `/unfriend <name>`, `/friends`.
+- Admins: `/kick <name>`, `/ban <name>`, `/unban <name>`, `/admin <name>`,
+  `/save`, `/time 08:00`, `/weather clear|cloudy|rain|storm|snow|blizzard|auto`,
+  `/set <rule> <value>` (changes it for everyone at once and saves it to
+  `server.json`: pvp, raiding, locks, death_penalty, sleep,
+  pause_when_empty, difficulty, wolf_grace_days, motd, server_name; bad
+  values are refused with what's allowed), `/say <message>`,
+  `/release-name <name>`.
+- Not built: `/backup` (comes with backups in M2.7) and `/rename` (the name
+  is the player's own, set in their profile; `/release-name` frees one).
 
-Chat: `T` to talk. It's global, so everyone on the server sees it (no
-proximity chat in v1).
+Chat: `T` to talk, Enter to send, Esc to cancel. It's global, so everyone
+on the server sees it (no proximity chat in v1). Lines fade after 14 s and
+all come back while you type. Plain chat is limited to a line every 0.4 s
+per player (commands aren't).
+
+**How the rules work** *(M2.6)*:
+- Pieces remember who placed them (and graves who died). Everyone's game
+  knows, so the prompt says "Bob's · Chest". Pieces from before M2.6 are
+  anyone's.
+- `locks`: who may open or take from chests and graves, open doors and use
+  beds. `owner_and_friends` (the default) lets the people you've
+  `/friend`ed in; `owner` keeps everyone else out; `off` opens everything.
+- `raiding`: taking down a piece you aren't allowed to use. Off by default.
+- `pvp`: with it off, weapons and arrows go straight through other players.
+  On, a swing at someone's avatar is checked on the server (reach,
+  weapon, stamina, cooldown) and arrows and thrown spears hit people.
+  Deaths say who did it ("Killed by Bob").
+- `death_penalty`: `grave` (default), `keep` (wake with everything) or
+  `drop_all` (it's all scattered where you fell, for anyone).
+- `difficulty`: easy / normal / hard scales hunger and diet drain (x0.75 /
+  1 / 1.3), animal and wolf damage (x0.7 / 1 / 1.4) and the pack (-1 / 0 /
+  +1 wolf).
+- `wolf_grace_days`: the day wolves move in; they hunt from the next night.
+- `sleep`: `all_online` (default), `half`, `anyone` or `off`.
