+The configuration file needs to edited, to add:
+
+* ``running_env=test``: to set the environment to use, ``test`` in this example.
+* ``encryption_key_test=xxxx``: to set the encryption key to use for a particular environment, ``test`` in this case.
+
+If no encryption key is set, the User Interface will suggest one when trying to save encrypted data.
+
+The data written in an ancrypted field is stored in a dedicated Model,
+``encryted.data``, that also holds the logic to encrypt and decrypt data.
+
+Separate values are stored for each environment.
+This means that if we set value "X" on the test environment,
+this value will only be available when the test environment is the active one.
