Adding SP groups to multiple document libraries using Powershell

Hello,

I have 100 Document libraries and respective 100 SP groups created in a site.

I  want to add those respective 100 sp groups one by one to respective document library.

For example I have document library with name " ABC" and group name "ABCGroup" so this needs to be added to "ABC" library.

I can create CSV file from which we can extract data.

How to achieve it through Powershell?

Please help.

Thanking you in advance.

Regards,

Jayashri
