+   git clone https://git.pontusmail.org/librecloud/im-a-server
+   ```
+
+2. **Install dependencies**
+
+   ```bash
+   bun install
+   npm install # or use npm
+   ```
+
+3. Now, you must choose whether to deploy with Docker or start a development server.
+
+### Start Development Server
+
+```bash
+bun dev
+```
+
+A server will now be available on port 3000.
+
+### Deploy with Docker
+
+You can edit the default `docker-compose.yml` file to your liking, then execute the following:
+
+```bash
+docker compose up -d --build # builds and runs in background
+```
