+
+```bash
+# Clone the repository
+git clone [email protected]:hacettepeoyt/hu-announcement-bot.git
+cd hu-announcement-bot
+
+# Create a virtual environment with venv and activate it 
+python3 -m venv .venv
+source .venv/bin/activate
+
+# Install the requirements
+pip install -r requirements.txt
+```
+
+Fill the missing configurations in `config.toml`. Then, run the following command:
+
+```bash
+python -m src -c <path/to/config.toml> -d <path/to/database.json>
