 - The daily check only alerts once per discount level per game. If the price drops further while still on sale, you get a new alert. If it goes back to full price and later goes on sale again, that is a new alert too.
 - Everything watched is stored in `games.json` in this folder, in plain text, so you can also open it directly if you ever want to see or edit the list by hand.
 - `games.json`, `owned.json`, `steamlinks.json`, `memory.yaml`, and `.env` hold your server's actual data and are left out of git (`.gitignore`) so they never end up in a public repo by accident. The installer creates each of these from its matching `.example` template automatically if it doesn't exist yet.
-- The installer manages the bot with [pm2](https://pm2.keymetrics.io), so once it's set up you can check on it with plain pm2 commands any time: `pm2 status` (is it running), `pm2 logs discord-game-price-bot` (live logs), `pm2 restart discord-game-price-bot`, `pm2 stop discord-game-price-bot`, and `pm2 delete discord-game-price-bot` (remove it from pm2 entirely - re-run the installer to add it back).

 - If you're upgrading from an older version of this bot that used launchd directly on macOS, `install.sh` detects and automatically removes that old service the first time you run it, so you don't end up with two copies of the bot running and double-replying in Discord.
 - To add, remove, or change greetings, edit `greetings.yaml`. Use `{user}` anywhere in a greeting and it gets replaced with a mention of the person who joined.
 - Same for goodbyes: edit `goodbyes.yaml`. Use `{user}` there too, it gets replaced with the username of whoever left (a plain name, not a mention, since Discord can't ping someone no longer in the server).
-- The join greeting posts to whichever channel is named `general` in your server.

 - Any Discord Scheduled Event on your server gets an automatic reminder posted to that same channel 15 minutes before it starts, like "Movie Night starting in 15 minutes!" Each event only gets reminded once. To change how far ahead it reminds, edit `EVENT_REMINDER_MINUTES` near the top of `index.js` and restart it.
 - `!info` gets platforms and Multiplayer/Co-Op/Cross-Play from that game's Steam store page when it has one. For non-Steam games (GOG/Epic exclusives etc.) there is no such lookup available, so "not listed" there means "couldn't confirm it," not "definitely single-player only."
 - The ownership count on `!info` combines two sources: anyone who ran `!own` for that game, plus anyone who linked their Steam profile with `!my-steam-profile` and actually owns it there. Discord itself has no concept of game ownership, so there is no fully automatic way to get this - `!own` needs people to mark their own games by hand, and `!my-steam-profile` only auto-detects Steam copies (not GOG/Epic) and only if that person's Steam profile has "game details" set to public. Everything self-reported through `!own` is stored in `owned.json`; Steam profile links are stored in `steamlinks.json`, both in this folder, in plain text.

 - If you don't want to make each person run `!my-steam-profile` themselves, you can link them yourself from the terminal (the easiest way if you already know your server members as Steam friends): run `bash install.sh --link-steam-profiles` (macOS/Linux) or `powershell -ExecutionPolicy Bypass -File install.ps1 -LinkSteamProfiles` (Windows). The first time, it asks for your own Steam profile once (to read your friends list from - it needs your Steam friends list privacy set to public, and remembers your profile after that so it won't ask again). Then it lists your Discord server's members for you to pick one by number, lists your Steam friends for you to pick one by number, links them, and asks if you want to link another (defaults to no). This does not restart the bot, so there is no need to run the installer again afterward. This is terminal-only by design - there's no Discord command for it, so members can't link (or relink) each other's profiles themselves.
 - The bot only replies to mentions of its trigger word if Ollama is installed, running, and has the model in `OLLAMA_MODEL` downloaded - without that, mentioning it gets no reply at all, and nothing is logged (check `bot.error.log` if you expect it to be working and it isn't replying). Each person can only trigger an AI answer once every 5 seconds; asking again sooner (or the Ollama request failing) just gets no reply rather than a second request, which keeps a burst of questions from bogging down your computer generating several replies at once.
 - `!remember SOMETHING` teaches it a permanent fact - a name, a preference, a correction like "don't call me buddy", or something about another member mentioned by name - that it will always take into account, even after the bot restarts. These facts are shared: anyone can ask about a fact someone else taught it, not just the person who typed `!remember`. They're saved to `memory.yaml` under whoever typed the command, and never expire on their own, unlike the short-term memory described below. `!forget SOMETHING` removes one you personally taught it (it has to match what you typed to `!remember`, word for word - use `!memories` to see the exact wording it has stored under your name), and `!forget all` clears everything you've had it remember. Each person can have up to 20 things remembered at a time.
-- `OLLAMA_MODEL` in `.env` controls which model it uses (`llama3.2` by default - small, fast, and good enough for short in-character replies). To use a different one, pull it yourself with `ollama pull MODEL_NAME`, set `OLLAMA_MODEL=MODEL_NAME` in `.env`, and restart it (re-run the installer, or `pm2 restart discord-game-price-bot`). Bigger models give better answers but take longer to reply and use more of your computer's memory.

 - It remembers each person's last 3 exchanges (their message and its reply) so it can follow up naturally and stick to things you told it earlier in the conversation, like a correction or a preference. This memory is per-person, kept only in the bot's running memory (not saved to disk), and forgotten automatically after 30 minutes of that person not mentioning it.
