 ## Introduction
 
-For this **pair-programming** activity we are going to use a [REPL](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop). You can find a REPL that runs in the browser for programming languages as JavaScript in [https://repl.it/languages/babel](https://repl.it/languages/babel).
+For this **pair-programming** activity we are going to have both people in the pair work in their own repos.
+At the end of the exercise, both students should have identical code in their respective repos.
