 ### gulp.registry([registry])
 
 Get or set the underlying task registry. Inherited from [undertaker]; see the undertaker documention on [registries](https://github.com/phated/undertaker#registryregistryinstance). Using this, you can change registries that enhance gulp in different ways. Utilizing a custom registry has at least three use cases:
 
 - [Sharing tasks](https://github.com/phated/undertaker#sharing-tasks)
-- [Sharing functionality](https://github.com/phated/undertaker#sharing-functionalities). (e.g. you could override the task prototype to add some additional logging, bind task metadata or include some config settings.)
+- [Sharing functionality](https://github.com/phated/undertaker#sharing-functionalities) (e.g. you could override the task prototype to add some additional logging, bind task metadata or include some config settings.)
 - Handling other behavior that hooks into the registry lifecycle (see [gulp-hub](https://github.com/frankwallis/gulp-hub) for an example)
