 Rust crate to check if a "Target" is available. The crate comes with the trait
 "Target" and ICMP/TCP based implementations of it. Additionally, the crate offers
-an async task Executor to perform availability checks of "Targets" on a regular basis.
+an async task executor to perform availability checks of "Targets" on a regular basis.
 
 ## Usage
 
 With this crate you can easily check if a computer is currently reachable over the network.
-Since all targets are implementations of trait "Target" the entire behavior is customizable.
+Since all targets are implementations of trait "Target" the availabilty check behavior is customizable.
 For example, it is easy to implement a custom Target to check if a Process is
 running or not.
