+=== Running the tests
+
+If you are willing to contribute with this project (we hope you are!), then you may need to run the tests locally. To do so, you must:
+
+* install **mongo-orchestration** link:https://github.com/10gen/mongo-orchestration[repo], by running **pip install mongo-orchestration**
+* stop any MongoDB instances you might have running.
+* Also stop Mongo Shell.
+
+Move to your project directory and start **mongo-orchestration** by running **mongo-orchestration start**. Then simply run the tests with **python -m unittest discover**.
+
+Just be sure that the ports __27017__ and __27018__ are not being used. You can verify it with the command __lsof__ :
+
+```
+sudo lsof -i :27017
+sudo lsof -i :27018
+```
+A MongoDB server mock will need these ports.
