+## How to run the examples
+This project contains examples for two lessons:
+* Sorting primitives => sort_primitives.go
+* Sorting slices => sort_slices.go
+
+Change the function that is being called in the main func of main.go.

+To run the sorting primitives example, change main,go to call sortPrimitives().
+
+To run the sorting slices example, change main.go to call sortSlices().
