Adoption? Need some help, mamas

So dh and I are exploring the idea of adopting. I was wondering if anyone had personal experiences, advice, guidance, good resources, etc. to help me along this process.
I have done so many google searches, but it is so much, it is hard to distinguish between advice and sales pitches. Sadly.

We are definetly doing a domestic adoption most likely through a state agency, as they are overloaded with children that need a good, loving home. I appreciate your support and advice in advance.
