Hyperkitty setup

Hello,

 I am trying to connect hyperkitty to mailman. I have cloned and set up mailman-hyperkitty
and made changes in the mailman_hyperkitty.cfg and mailman.cfg files. But, still I am
unable to see anything in hyperkitty(except the login page).I have injected mails to a
list using mailman inject -f email.txt test(a)example.net but couldn't see anything
there. "No archived lists yet" is shown there.I checked the MailingList through
command line and found that it is empty. 
I would be grateful if someone could help.

Regards,
Aditi
