 A GitHub Action to run [dbt](https://www.getdbt.com) commands in a Docker container. It uses the official images provided by [Fishtown Analytics](https://hub.docker.com/r/fishtownanalytics/dbt/tags). You can use [dbt commands](https://docs.getdbt.com/reference/dbt-commands) such as `run`, `test` and `debug`. This action captures the dbt console output for use in subsequent steps.
 
 ### dbt version
+The current version of the dbt is 1.0.0. Please note that 1.0.0. may require some changes to your dbt project structure compared to 0.x.x.
