CTFtime

CTFtime is mostly an authentication method, which you can learn how to configure here. However, as shown in the showcase, the CTFtime weight can be displayed in the social image even if CTFtime authentication is not enabled. This requires setting the client_id in the ctftime section of the config.yaml. The client_secret is not required for this feature.

ctftime:
  client_id: # your CTFtime OAuth Client ID
