Can't understand where to enter mbed license key

Dear friends,

I'm new in STM32 and MBED OS. So, sorry if my question may be a little stuped.

Can you please help me to register my nucleo board on MBED OS website? I have a Nucleo F411RE. board . My compiler does not want to work without licensing and shows me a warning message L9931W. I read that i need to open mbed.htm in my board's drive to enter a license key. I open a link but it shows my board's description page https://os.mbed.com/platforms/ST-Nucleo-F411RE/. Nothing more. What is my problem?
