 # kaczynski-bot-2.0
 
-To install dependencies:
+A Discord bot built with [Bun](https://bun.com).
+
+## Setup
+
+Install dependencies:
 
 ```bash
 bun install
 ```
 
-To run:
+Create a `.env.development` file with:
 
-```bash
-bun run 
+```
+DISCORD_TOKEN=your-bot-token
 ```
 
-This project was created using `bun init` in bun v1.3.0. [Bun](https://bun.com) is a fast all-in-one JavaScript runtime.
+## Development
+
+```bash
+bun run dev
+```
+
+## Commands
+
+Commands live in `src/cmd/registry/` and are loaded automatically at startup — drop a file default-exporting a `Command` in that folder to register it, no manual wiring required.
+
+## Data persistence
+
+Bot state (e.g. limbo mode) is persisted to `data/data.json` via `DataService`. That path is gitignored.
+
+## Production build
+
+```bash
+bun run build
+```
+
+Bundles `src/index.ts` and every file in `src/cmd/registry/` into `dist/`. Run the result with:
+
+```bash
+bun dist/index.js
+```
+
+## Docker
+
+Build the image:
+
+```bash
+docker build -t kaczynski-bot .
+```
+
+Run it, mounting a volume so `data/data.json` survives container restarts:
+
+```bash
+docker run -d \
+  -e DISCORD_TOKEN=your-bot-token \
+  -v kaczynski-bot-data:/app/data \
+  kaczynski-bot
+```
