 ## What we do
 
-The .gov team manages the .gov top-level domain.
+We manage the .gov domain registry. This includes the .gov registrar.

+- A **registry** contains domain names and registrant information for a top-level domain (like .gov, .com, or .us).
+- A **registrar** manages domain name registration.
 
-### .Gov domain name registration
+### We are the authoritative source for all .gov domain names and registrants
 
-We manage domain name registration for .gov. We are the .gov registrar. (A registrar manages domain name registration.) You can only request and register .gov domain names through us. We make it easy for eligible government organizations to register .gov domains. We verify the identity and eligibility of everyone who requests a .gov domain.
+We manage the authoritative record of all .gov domain names and their registrants. We ensure that .gov domain names resolve in the global domain name system (DNS). DNS maps easy-to-remember names to hard-to-recall numbers. For example, this allows us to use “cisa.gov” instead of something like “104.106.178.124.”
