+## Running Tests on Travis
+
+[Travis](https://travis-ci.org/) automatically runs tests whenever a github
+repo changes.  To have Travis automatically run tests on your forked copy
+of this repo:
+
+1.  Fork this repo on [GitHub](https://github.com/).
+2.  Visit the
+    [Google Developers Console](https://console.developers.google.com/) and
+    choose an existing project or create a new project.
+3.  Under `APIs & auth`, choose Credentials.
+4.  Click `Add credentials`, and then click `Service account`.
+5.  Under `Key type`, choose `JSON`, and then click `Create`.  A json credential
+    file will be downloaded to your computer.
+6.  Visit [Travis](https://travis-ci.org/profile ) and turn on Travis for your
+    new forked repo.
+7.  Go back to the [Travis](https://travis-ci.org/) home page, click on your
+    repo, then click on `Settings`.
+8.  Under Environment Variables, set GOOGLE_CLOUD_PROJECT to the project id
+    for the project you created or chose in step 2.
+9.  Base-64 encode the json file you downloaded in step 5.  On unix machines,
+    this can be done with a command like
+    `base64 -w 0 < my-test-bf4af540ca4c.json`. 
+10. Under Environment Variables, set GOOGLE_CREDENTIALS_BASE64 to the
+    base64-encoded json from step 9.  **Be sure te leave `Display value in build
+    log` switched OFF.**
