 If being run as part of a Travis build for a merged commit, the
 encrypted `key.json` file need be decrypted before running tests.
+
+Before encrypting:
+
+* Visit ``https://github.com/settings/tokens/new``, get a token,
+  and store the token in travis.token file.
+* Visit
+  ``https://console.cloud.google.com/apis/credentials?project={PROJ}``
+* Click "Create credentials >> Service account key", select your
+  service account and create a JSON key (we'll call it ``key.json``)
+
+Encrypt the file via::
+
+$ travis login --github-token=$(cat travis.token)
+$ travis encrypt-file --repo=GoogleCloudPlatform/google-cloud-python key.json
+
+After running ``travis encrypt-file``, take note of the ``openssl`` command
+printed out. In particular, it'll give the name of the key and
+IV (initialization vector) environment variables added to the Travis
+project.
+
+See:
+https://docs.travis-ci.com/user/encrypting-files/
