New to Solana .... as a validator

I am starting your validator program and I would like you to indicate the tasks and commands that I must do as a validator. I write from Bolivia and I am willing to run as a validator. I understand the programming that I already installed, but beyond that, what I must do … Reading in some forums or advice on the web, it is not clear to me that if I must execute transactions and I must obtain them or as in other instances I must execute commands so that my computer in the background work executing transactions that you send … Thanks
