+#### Using Claude Code in the Container
+
+1. Set up your API key:
+```bash
+# Copy the environment template
+cp docker/template.env docker/.env
+
+# Add your Anthropic API key to docker/.env
+echo "ANTHROPIC_API_KEY=your_api_key_here" >> docker/.env
+```
+
+2. Start the development environment:
+```bash
+make dev-env
+```
+
+3. Inside the container, use Claude Code:
+```bash
+# Interactive mode (asks for permission before each action)
+claude
+
+# Autonomous mode (runs without permission prompts)
+claude --dangerously-skip-permissions
+```
+
+**Note**: The `--dangerously-skip-permissions` flag allows Claude to work autonomously. Use with caution and always review changes before committing.
