-This sketch demonstrates how to write charging parameters,read charger state and monitor charging using the PowerManagement library:
-* In the setup() function, it sets the charging parameters
-* In the loop() functionit prints the battery's voltage, current, percentage and the charger's state allowing you to monitor charging. 
+  This sketch demonstrates how to write charging parameters,read charger state and monitor charging using the PowerManagement library:
+  * In the setup() function, it sets the charging parameters
+  * In the loop() functionit prints the battery's voltage, current, percentage and the charger's state allowing you to monitor charging. 
 
   Requirements:
   - Arduino Portenta C33, Arduino Portenta H7, Arduino Nicla Vision
   - Arduino IDE
   - PowerManagement library (installable from the Arduino Library Manager)
 
   Usage:
-  1. Install the required library:
-     - Open the Arduino IDE.
-     - Go to "Sketch" -> "Include Library" -> "Manage Libraries..."
-     - Search for "PowerManagement" and install it.
 
+  1. Connect the Battery:
+  
   2. Upload the Sketch:
-     - Open the provided sketch in the Arduino IDE.
-     - Select your board type and port from the "Tools" menu.
-     - Click the "Upload" button to upload the sketch to your board.
+    - Open the provided sketch in the Arduino IDE.
+    - Select your board type and port from the "Tools" menu.
+    - Click the "Upload" button to upload the sketch to your board.
 
   3. Monitor Serial Output:
-     - Open the Serial Monitor in the Arduino IDE.
-     - Set the baud rate to 115200.
-     - You will see the sketch continuously printing battery status and charger state.
+    - Open the Serial Monitor in the Arduino IDE.
+    - Set the baud rate to 115200.
+    - You will see the sketch continuously printing charger state information.
