What does the phrase "Enter a .crypto or .zil domain" mean?

There  is a significant  learning curve regarding crypto and Litecoin. Many people struggle to do the basic steps to make sure they are sending Litecoin to the correct address.

This is obviously a big problem. There is no limit to the amount of Litecoin managed in Litewallet. Accidentally sending the wrong address can really ruin someone's day.

One solution, provided by our partner Unstoppable Domains is to allow people to register vanity domains with their Litecoin address.  

So, instead of sending to MUJBtCqUeTTdpWLdUGxEjPhiMhopbPKG3U they can just type in 

litewallet-donation.crypto 

Litewallet does a domain lookup and updates the send address!
