@BotFather will help you to register your own bot. Copy your bot token. In QuAn goto /menu - personal bot - add bot (paste the token).
Add your /commands in botfather then initiate them in QuAn. You can link some poll to the command, for example, welcome speach & picture.
Add admins to the personal bot and they will get access to your QuanBot polls and possibility of new polls creation/publishing.
