+# Find safe places in Java
+
+## Requirements
+
+For this exercise we will use Java 8.
+You need to have the JDK8 installed and added to your path.
+
+
+## Running the tests
+
+### Activating the tests
+To activate the tests just delete the @Ignore annotation on each test method
+
+The tests are grouped into 3 levels which each represent a method to be implemented
+(see the comments before and after each group of tests) so you can implement and test each method
+on its own
+
+### Windows
+To run the tests in a Windows environment navigate into the project directory 
+and execute ```./gradlew.bat test```
+
+### Linux/MacOS
+To run test in a Linux or MacOS environment navigate into the project directory
+and execute ```./gradlew test```
