 ### LoggerMixin
 
-LoggerMixin adds capabilities to a LoopBack Next Application by adding a `.logger()` function that allows used to bind a Logger class to `Context` automatically. The binding key will be `loggers.${Class.name}` where `Class.name` is the name of the Logger class being bound. The Mixin also overrides existing `.component()` function so that components are also capable of providing Logger's to be bound automatically. 
+LoggerMixin adds capabilities to a LoopBack Next Application by adding a `.logger()` function that is used to bind a Logger class to `Context` automatically. The binding key will be `loggers.${Class.name}` where `Class.name` is the name of the Logger class being bound. Components are also able to provide their own Logger implementation which will be bound via `.component()` automatically when using this Mixin.
