 > Automatic i18n markdown translation and i18n phrase translation using Google Translate
 
-> **v2.0.0**: We have integrated Redis as a requirement for caching Google Translate responses (to save you money)
->
-> **v1.0.0**: We now use the official Node.js Google Translate package `@google-cloud/translate`

+## Requirements
 
+### Redis
 
-## Requirements
+You will need to have [Redis][] installed in order for caching to work properly.
 
-You will need to have [Redis][] installed.
+If you do not plan to use Redis, then set `redis: false` as an option.
+
+### Google Application Credentials
+
+You will also need Google Application Credentials, and you will need to set them as environment variables (e.g. `GOOGLE_APPLICATION_CREDENTIALS=/home/user/Downloads/service-account-file.json`).
+
+For more information on Google Application credentials, see <https://cloud.google.com/docs/authentication/getting-started#setting_the_environment_variable>.
