+# Rabbits vs Hunter
+
+## Goal
+
+This projects manages a rabbit hunt.
+It's possible to change some criteria such as trees, burrows and rabbits counts.
+
+
+## Building
+
+Using maven, just execute the following command :
+```
+mvn clean package
+```
+
+In the new _target_ folder, you will find the _rabbits-vs-hunter-[version]-jar-with-dependencies.jar_ jar file. This jar contains all dependencies.
+
+## Running
+
+Execute the built jar :
+```
+java -jar rabbits-vs-hunter-[version]-jar-with-dependencies.jar
+```
