+ 
+### Tests
 
-## Tests
+The code in the wrapper can be tested by running the `runit/univariate_runtests.R` R file
+
+You will need to install **RUnit** package in order to make it run:
+```r
+install.packages('RUnit', dependencies = TRUE)
+```
 
-The code in the wrapper can be tested by running the **tests/univariate_tests.R** in R  
+### Working example
