 ## History
 
-The idea of creating this roadmap came from an old roadmap designed by [vazeri](https://github.com/vazeri) which was not updated for years.
+The idea of creating this roadmap came from a [roadmap](https://github.com/vazeri/Embedded-Engineering-RoadMap-2018) designed by [vazeri](https://github.com/vazeri) which was not updated for years.
