+1. Follow the instructions [here](https://developers.google.com/earth-engine/guides/service_account#use-a-service-account-with-a-private-key) to create an Earth Engine service account.
+2. Create a private key for the service account
+3. Download the JSON key file
+4. Open the JSON key file and copy the entire content of the file and set it as the value for the environment vaiable `EARTHENGINE_TOKEN`
