+
+## Using Built-in Bots
+
+Built-in bots run inside the dumpsterChat server. No SSH, no separate process.
+
+1. Go to **/bots/manage** in the web UI
+2. Click **[CREATE BOT]**
+3. Name it, pick a type from the dropdown (e.g. "Steam Free Games")
+4. Select the server and channel to post to
+5. Click **[SAVE]**
+
+The bot starts immediately. It restarts automatically when the server restarts.
+
+### Adding New Built-in Bot Types
+
+Three touch points:
+
+1. **`internal/bot/yourbot.go`** — write a `BotFunc` that takes `(ctx, config, send)`
+2. **`cmd/server/main.go`** — register it: `botRunner.Register("yourbot", bot.YourBot)`
+3. **`web/src/components/BotManager.tsx`** — add config fields to `BOT_TYPE_CONFIGS`
+
+## Running External Example Bots
+
+External bots connect via WebSocket and run as separate processes.
+
+### Modbot
+
+```bash
+cd examples/modbot
+BOT_TOKEN=your_bot_token go run main.go
+```
+
+### Welcome Bot
+
+```bash
+cd examples/welcome
+BOT_TOKEN=your_bot_token DUMPSTER_HOST=dumpster.dustin.coffee go run main.go
+```
+
+### Steam Free Games (standalone)
+
+```bash
+cd examples/steamfree
+BOT_TOKEN=your_bot_token CHANNEL_ID=channel-uuid DUMPSTER_HOST=dumpster.dustin.coffee go run main.go
+```
