 ## Installing from PyPI
 
 On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
 
 ```
+
 pip3 install seeed-python-mlx90640
+
 ```
 
 To install system-wide (this may be required in some cases):
 
 ```
+
 sudo pip3 install seeed-python-mlx90640

+if you want to update the driver locally from PyPI. you can use:
+
+```
+pip3 install --upgrade seeed-python-mlx90640

 ## Usage Notes
 
 First, Check the corresponding i2c number of the board:
+
 ```
+
 (.env) pi@raspberrypi:~ $ ls /dev/i2c*
 /dev/i2c-1
+
 ```
 
 Check if the i2c device works properly， 0x33 is the MLX90640 i2c address.
