Top up Petty Cash - How do I record this in Books?

I'm new to Books and I have no background in Accounting.

I received cash (not a payment) from someone so I can top up our organization's petty cash. My questions are:

1. How do I show in Books that I received the money?
2. How do I show in Books that that money is now part of Petty Cash (I have this account in Books)?

Update:

This is what I did:

1. Created Other Current Asset and named it 'Cash from NAME'.
2. Then, I recorded a transfer from 'Cash from NAME' to 'Petty Cash'.

Are these correct?
