 Dead simple native Python GRIB 2 data processing
 
-*More to come soon*
+## Running the tests
+
+Because of the way that python 3 handles packages, you cannot run the test scripts directly. Instead run them as shown below:
+
+```bash
+cd /path/to/grippy
+cd ../
+python -m grippy.test_fetch.py
+python -m grippy.test_wvper.py
+```
+
+If those run succesfully, you are good to go.
