 2.  **Configure the Code:**
-    - Open the `esp32_MachineNotify.ino` file.
+    - Copy `secrets_template.h` to a new file named `secrets.h` in the same directory.
-    - Replace the placeholder values for `WIFI_SSID`, `WIFI_PASSWORD`, and `NTFY_TOPIC` with your WiFi credentials and desired `ntfy.sh` topic.
+    - Open `secrets.h` and populate `SECRET_WIFI_SSID`, `SECRET_WIFI_PASSWORD`, and `SECRET_NTFY_TOPIC` with your WiFi credentials and desired `ntfy.sh` topic.
+    - The `secrets.h` file is ignored by git to keep your credentials safe.
 
 3.  **Upload the Code:**
     - Connect your ESP32 board to your computer.
