Acclerate access speed

 You could add these three lines to the hosts file in the %systemroot%/system32/drivers/etc folder:

            140.82.114.4 github.com
            185.199.108.153 assets-cdn.github.com
            199.232.69.194 github.global.ssl.fastly.net
            

 After that, you can launch the terminal and input this command:

                ipconfig /flushdns
