Documentation can be enabled for a job in dbt Cloud by checking the "Generate docs?" checkbox on the Job Settings page, as shown below. Once this setting is enabled, subsequent runs of the job will automatically include a step to generate documentation.
To view the latest documentation for a job, click the "View Latest Documentation" button from the Job Details page. This link will always navigate you to the most recent version of your project's documentation in dbt Cloud.
