+    ```bash
+    sudo pacman -S tesseract tesseract-data-eng
+    yay -S mongodb-bin
+    # Optional
+    yay -S mongodb-compass  # Manage the database with a GUI
+    ```
     > Tesseract works on Linux way better than Windows, but oh well.
+2. Clone the repository.
 3. Set up your MongoDB database.
     > The free tier in MongoDB Atlas is NOT enough as it is limited to 500 entries only.
 4. Set up the required environment variables, which contains these variables:
