 # Dev Container Build and Run (devcontainers/ci)
 
-The Dev Container Build and Run GitHub Action is aimed at making it easier to re-use [Dev Containers](https://containers.dev) in a GitHub workflow. The Action supports using a Dev Container to run commands for CI, testing, and more, along with pre-building Dev Container image. Dev Container image building supports [Dev Container Features](https://containers.dev/implementors/features/#devcontainer-json-properties) and automatically places Dev Container [metadata on an image](https://containers.dev/implementors/spec/#image-metadata) label for simplified use.

 A similar [Azure DevOps Task](./docs/azure-devops-task.md) is also available!
 
 Note that this project builds on top of [@devcontainers/cli](https://www.npmjs.com/package/@devcontainers/cli) which can be used in other automation systems.
