Need a User Guide for LiteCoin Core Wallet

A few questions:

  1. Does a User Guide exist for the LiteCoin Core Wallet?
  2. I have an account at and in my Account Settings, what data should I enter for the Payment Address?
  3. Each time I click Receive and get a new address, it is different, so how does the Payment Address match with my antMiner L3 Worker Address?


I am hoping someone can answer questions above.
Thank you
