or not.

 ## Summary
 
-This package contains a BEAM pipeline that populates a Cloud SQL database from a Datastore backup.
+This package contains a BEAM pipeline that populates a Cloud SQL database from a
+Datastore backup. The pipeline uses an unsynchronized Datastore export and
+overlapping CommitLogs generated by the Nomulus server to recreate a consistent
+Datastore snapshot, and writes the data to a Cloud SQL instance.
+
+## Pipeline Visualization
+
+The golden flow graph of the InitSqlPipeline is saved both as a text-base
+[DOT file](../../../../../../test/resources/google/registry/beam/initsql/pipeline_golden.dot)
+and a
+[.png file](../../../../../../test/resources/google/registry/beam/initsql/pipeline_golden.png).
+A test compares the flow graph of the current pipeline with the golden graph,
+and will fail if changes are detected. When this happens, run the Gradle task
+':core:updateInitSqlPipelineGraph' to update the golden files and review the
+changes.
