 ## Software Requirements
-This project uses Python 3. The required dependencies are:
-*   `RPi.GPIO` (usually pre-installed on Raspberry Pi OS)
-*   `pygame` (used for optimized audio playback)
+This project uses Python 3 and `uv` for dependency management. To set up the environment:
 
-You can install the required packages via:
+1. Install `uv` if you haven't already:
+   ```bash
+   curl -LsSf https://astral.sh/uv/install.sh | sh
+   ```
+2. The project contains a `pyproject.toml` file with all dependencies.
+   ```bash
+   uv sync
+   ```
+
+Note: The system also requires `python3-pygame` and `python3-rpi.gpio` which should be installed via system packages:
 ```bash
 sudo apt-get install python3-pygame python3-rpi.gpio
 ```

-## Automating with Cron
-To have the alarm start automatically at a specific time (e.g., 6:45 AM on weekdays), you can set up a cronjob.
+## Automating and Managing Alarms (GraphQL API)
 
-1. Open your crontab configuration:
+Instead of manually editing your crontab, this project provides a simple GraphQL API to List, Get, Set, and Delete your alarms.
+
+### API Setup & Authentication
+
+1. Create a `.env` file in the project root to set up your Static API Key:
    ```bash
-   crontab -e
+   cp .env.example .env
+   # Edit .env and set your own secure API_KEY
    ```
-2. Add the following line at the end of the file (adjust the paths if your setup differs):
+2. Start the API server:
    ```bash
-   45 6 * * 1-5 cd /home/pi/workspace/wecker && /usr/bin/python3 wecker.py > /home/pi/workspace/wecker/cron.log 2>&1
+   uv run uvicorn api.main:app --host 0.0.0.0 --port 8000
    ```
-   * `45 6`: Runs at 6:45 AM.
-   * `* * 1-5`: Runs from Monday (1) to Friday (5). Skips the weekend.
-   * It ensures the script runs in the correct directory so it can find the audio file.
+3. The API will be available at `http://<YOUR_PI_IP>:8000/graphql`.
+
+**Authentication:** All requests to the `/graphql` endpoint require a custom header:
+`X-API-Key: <YOUR_API_KEY>`
+
+### Example API Usage
+
+**Get all alarms:**
+```graphql
+query {
+  getAlarms {
+    id
+    cronExpression
+    command
+    isEnabled
+  }
+}
+```
+
+**Set an alarm:**
+```graphql
+mutation {
+  setAlarm(
+    cronExpression: "45 6 * * 1-5", 
+    command: "cd /home/pi/workspace/wecker && /usr/bin/python3 wecker.py > wecker.log 2>&1",
+    isEnabled: true
+  ) {
+    id
+    cronExpression
+  }
+}
+```
+
+**Delete an alarm:**
+```graphql
+mutation {
+  deleteAlarm(id: "YOUR-ALARM-ID")
+}
+```
+
