Is there any Documentation for Desktop Multisig wallet

Are there any documents or online tutorials that walk you step by step on how to use the desktop version of the multisig wallet? I have found videos, but they are not so easy to follow, especially with no audio. I need something to walk me through how to use the desktop version with a ledger nano s. So far, I have figured out how to set up the wallet, set the owners, deposit money into the wallet, and set up the required number of signers. After that I am stuck. I can start a transaction to move ether into another account, but i cannot figure out how everyone is to sign off. And there are also a lot of options that I don’t know what they are for. If anyone could help, that would be great.
