Need to recreate /etc/yum.repolist.d/ repositories for Centos8

Hi ,
I was trying to install CRC in my Centos 8 , and by mistake i have deleted /etc/yum.repolist.d/ repositories. I have tried many options and not able to find anything.
Does anybody know how to re-create repositories for /etc/yum.repolist.d

Please help.

Thanks,
