Where to find information on handshake messsages a new node needs to exchange with a peer?

Question

So I am looking to dig further into how new nodes join the ethereum network. I am looking at studying this for both the execution and consensus layer.

Specifically I am interested in knowing:

1. How do new nodes find new peers
2. When new peers are found, I believe some handshake will have to occur? Where can I find the handshake specification?
