Clone this repository to the CTFd/plugins folder.

1. Navigate to this plugin configuration panel in admin page.

2. In 'Option' tab, choose whether invited teams need to fill in a unique token or just the invited email address for registration.

3. In 'Invite' tab, upload CSV file with invited team name and email for each line.

   Example

   Team1,team1@email.com
   Team XYZ,teamxyz@email.com
   "Team,comma",teamcomma@email.com
   "Team,comma""quote""",teamcommaquote@email.com
   

4. In 'Invited Teams' tab, you can export invited teams and unique token for each team in CSV format. You can also remove the invitation or see which teams are already registered.

5. If you have configured Email in your CTFd installation, you can also automatically send invitation (with token if you choose 'invited teams need to fill a unique token') to all invited emails.

This plugin use modified registration page from original template of CTFd. You can modify private-registration-token.html and private-registration-email.html to suit your needs.
