 ## Ballot
 
-Consul service election with tagging support and hooks
+Consul based leader election with tagging support and hooks
 
 ### What is it?
 
-Consul doesn't support leader election for registered services. This tool is meant to help with that.
-The idea is that you have multiple services and you need to select a leader. It will apply a tag of choise
-to the leader and when a election happens you can hook a script execution.
-This tool can be very useful for setups that require a leader service, but do not offer a leader election out of the box.
+Consul lacks a built-in feature for leader election among registered services. This tool is designed to fill that gap. It functions by designating a leader among multiple services, marking the chosen leader with a specified tag. Additionally, it allows for the execution of a script whenever a leader election occurs.
 
 ### How do I test it?
