 ### Adding new hooks implementations
 
-Adding a new hook implementation is trivial. You should implement interface hook with method `call`  which inputs `entry zapcore.Entry`. Also you need impelement init method which inputs configuration as [Viper](https://godoc.org/github.com/spf13/viper#Viper) config and returns new instance of the Hook structure. Then register the new hook

 type by calling RegisterHookType() function from init() method. Please see "email" hook implementation as example in hook.go file.
