The **Add markdown text** step renders a block of Markdown inside the pipeline. It does not read or modify the data — it exists to document the pipeline for whoever opens it next. ## Configuration | Field | Description | | ------- | ----------------------------------------------------------------------------------------- | | Content | The Markdown to render. Supports headings, lists, links, bold and italic, and code spans. | ## What to use it for * Explaining a non-obvious transformation or the assumption behind a formula. * Recording where a source dataset came from and how often it updates. * Splitting a long pipeline into labelled sections so the step list is readable. * Noting known caveats in the data for downstream consumers. A pipeline that publishes a dataset other people rely on is worth documenting inline. The Markdown step keeps that context next to the logic it describes, rather than in a separate document that drifts out of date. This step affects only what is displayed in the pipeline editor. It passes its input through unchanged, so it is safe to insert anywhere. ## Next steps Save the pipeline output as a dataset. Produce a downloadable, embeddable snapshot.
