 # Weather Station
 
 Code for the indoor Weather Station
+
+## Step 1: Install and Pass the "Variable"
+
+Move the template file to the system folder and reload the daemon:
+
+* `sudo cp weather-station@.service /etc/systemd/system/`
+* `sudo systemctl daemon-reload`
+
+---
+
+## Step 2: Enable and Start
+
+Now, when you enable and start the service, you **append your actual username** right after the `@` symbol.
+
+If your username was `pi-user`:
+
+* **Enable it to start on boot:**
+
+   `sudo systemctl enable weather-station@pi-user.service`
+* **Start the script right now:**
+
+   `sudo systemctl start weather-station@pi-user.service`
+
+---
+
+## Step 3: How to check on it
+
+* **To see if it's running:**
+
+  `sudo systemctl status weather-station@pi-user.service`
+* **To read the live console output (like seeing the print statements):**
+
+  `sudo journalctl -u weather-station@pi-user.service -f`
+  *(Press `Ctrl+C` to exit the log view)*
+
+* **To manually restart it (if you update your code):**
+
+  `sudo systemctl restart weather-station@pi-user.service`
