The first step in getting started with the platform is to create an account, which you can do here:
You won’t need to provide much information, but be certain to use an email address you have access to in the event that you need to reset your password. The name you provide will be displayed in the scoreboard during a competition.
Once your account is created you will be able to login to the system. Keep in mind that you are now a regular user and only have access to publicly accessible CTFs and private CTFs that you have been invited to by the organizer.
After login you will be presented with your dashboard – this allows you to manage all of the CTFs you are currently participating in.
