+# Running the gs elements locally
+
+When running from the command line or in a container running locally, simply
+set the credentials by exporting GOOGLE_APPLICATION_CREDENTIALS. If you are
+not familiar with this environment variable, check the documentation
+https://cloud.google.com/docs/authentication/getting-started
+Note that you can restrict a service account to the role Storage Admin or
+Storage Object Creator instead of the Project Owner role from the above
+documentation.
+
+# Running the gs elements in Google Cloud Run
+
+Add the Storage Object Viewer role to the service account assigned to the
+Cloud Run service where gssrc runs. For gssink add the role Storage Object
+Creator. Then just set the service-account-email property on the element.
+
+# Running the gs elements in Google Cloud Kubernetes
+
+You need to set GOOGLE_APPLICATION_CREDENTIALS in the container and ship the
+json file to which the environment variable points to.

+ * Write incoming data to a series of sequentially-named remote files on a
+ * Google Cloud Storage bucket.
+ *
+ * The object-name property should contain a string with a \%d placeholder
+ * that will be substituted with the index for each filename.
+ *
+ * If the #GstGsSink:post-messages property is %TRUE, it sends an application
+ * message named `GstGsSink` after writing each buffer.
+ *
+ * The message's structure contains these fields:
+ *
+ * * #gchararray `filename`: the filename where the buffer was written.
+ * * #gchararray `date`: the date of the current buffer, NULL if no start date
+ * is provided.
+ * * #gint `index`: index of the buffer.
+ * * #GstClockTime `timestamp`: the timestamp of the buffer.
+ * * #GstClockTime `stream-time`: the stream time of the buffer.
+ * * #GstClockTime `running-time`: the running_time of the buffer.
+ * * #GstClockTime `duration`: the duration of the buffer.
+ * * #guint64 `offset`: the offset of the buffer that triggered the message.
+ * * #guint64 `offset-end`: the offset-end of the buffer that triggered the
+ * message.
+ *
