Can someone tell me how escrow works?

[erisi121]

So I posted some ads of me selling some stuff in the unverified advertisement section.
I obviously accept escrow , but the point is that I don't know how it works here.
I read that the buyer needs to ask Mak to load his account with money , but I don't get what happens after the deal finishes and the funds are supposed to be released to me.
How am I supposed to get them out of my account in BTC (if possible)?
Thanks in advance!
