 ## Board Operation
 
 ### Getting Started - IDE
-
 If you want to program your **MKR IoT Carrier Rev2** while offline you need to install the Arduino Desktop IDE <sup>[**[1]**](#10-reference-documentation)</sup>. To connect the **MKR IoT Carrier Rev2** to your computer, you’ll need a Micro-B USB cable. This also provides power to the board, as indicated by the LED.
 
 ### Getting Started - Arduino Web Editor
-
 All Arduino boards, including this one, work out-of-the-box on the Arduino Web Editor <sup>[**[2]**](#10-reference-documentation)</sup>, by just installing a simple plugin.
 
 The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and support for all boards. Follow <sup>[**[3]**](#10-reference-documentation)</sup> to start coding on the browser and upload your sketches onto your board.
 
 ### Getting Started - Arduino IoT Cloud
-
 All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to log, graph and analyze sensor data, trigger events, and automate your home or business.
 
 ### Sample Sketches
-
 Sample sketches for the **MKR IoT Carrier Rev2** can be found either in the “Examples” menu in the Arduino IDE and further documentation can be found in Arduino Documentation <sup>[**[7]**](#10-reference-documentation)</sup> which also contains links to the troubleshooting articles.
 
 ### Online Resources
-
 Now that you have gone through the basics of what you can do with the board you can explore the endless possibilities it provides by checking exciting projects on ProjectHub <sup>[**[4]**](#10-reference-documentation)</sup>, the Arduino Library Reference <sup>[**[5]**](#10-reference-documentation)</sup> and the online store <sup>[**[6]**](#10-reference-documentation)</sup> where you will be able to complement your board with sensors, actuators and more.
 
 ### Board Recovery
-
 All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double-tapping the reset button right after power up.
