+
+### Tests
+
+The code in the wrapper can be tested by running the `runit/biosigner_runtests.R` R file
 
-## Tests
+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/biosigner_tests.R` in R  
+### Working example
