+# Earth Engine App
+
+The Earth Engine is a Tethys App that demonstrates how to use Google Earth Engine to visualize remotely sensed datasets.
+
+## Installation
+
+Install the app with the Tethys Platform environment activated as follows:
+
+```
+# For development installations
+tethys install -d
+
+# For production installations
+tethys install
+```
+
+## Settings
+
+The app has two Custom Settings that can be used to configure the app to use a [Google Earth Engine service account](https://developers.google.com/earth-engine/service_account):
+
+* **service_account_email**: Email associated with the service account.
+* **private_key_file**: Path to service account JSON file containing the private key.
+
+## Authenticate for Development
+
+Alternatively, you can authenticate with your personal Google Earth Engine account by running the following command:
+
+```
+earthengine authenticate
+```
+
+**WARNING**: Do not use personal Google Earth Engine credentials for a production installation.
