No authorization for SiFive board definitions in Arduino IDE

Page 15 of the Freedom E310 Arty FPGA Getting Started Guide provides the following address for making the SiFive boards known to the Arduino IDE:

However, when attempting to open that link, I get “access denied” response.

How can I obtain access?

Many thanks.

Are you sure you’ve entered the correct URL into the Arduino IDE? The error message in the screenshot you posted is missing the /bsp/ part of the URL.

Ah, I see now that there is an error in the screenshot in the guide, but not the text instructions. I’ll update the guide with the correct URL.
