-- The provisioning script has the following format:
+- Open a terminal and navigate to the cloned `/arduino_matter_provision` folder.
+- The provisioning command has the following format:
 
-  `python arduino_matter_provision.py <board_name> <config_number>`
+  ```bash
+  python arduino_matter_provision.py <board_name> <config_number>
+  ```
 
 - Replace `<board_name>` with `nano_matter` and choose a configuration number (e.g., `1`):
-
-  `python arduino_matter_provision.py nano_matter 1`
+  ```bash
+  python arduino_matter_provision.py nano_matter 1
+  ```
 
 - Run the script to change the provisioning data using the given structure.

 Here’s what the new credentials might look like:
