How do I use Paid Subscription

[temp123]

Hi all,

I am using SMF 1.1.4 version. I installed Paid Subscription 0.18 version in my SMF software. Actually, I want to charge my users when they become members of my community and I can provide time period for 3,6 months,etc.
But I don't know how Paid Subscription package works in SMF.
Please, Help me out.
