 ## Testing
-MojitO/S provides a utility for correctness testing. It is located in the ext_tester directory and can be expanded easily with new tests.  
-This utility requires `mojitos` to be built first, and can then be ran by running `make run` in the ext_tester directory.  
+MojitO/S provides a utility for correctness testing. It is located in the `tester` directory and can be expanded easily with new tests.  
+This utility requires `mojitos` to be built first, and can then be ran by running `make run` in the tester directory.  
 
 It works by running `mojitos` multiple times with different parameters, and running its output through different verification functions each time.
