We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.
1 - The pipelines should be as minimal as possible and self-contained.
2 - When possible, use public sources (public PubSub topic, GCS bucket, BQ table...) . If this is not possible, add a comment explaining the needed process.
3 - It's OK to add comments as clarifications.
4 - Use logging as a way to show the pipeline is correct, for example, if the pipeline reads from a source, add a step that handles the read element and log it. If the amount of logging is considerable, add an aggregation or filter step.
5 - No need to add dead letter paths to the pipeline, unless required by the use case.
