# Popular Environments

The DNAstack Client Library can be used from within your bioinformatics workflows on almost any platform or engine. This section demonstrates the execution of a simple workflow on a variety of popular environments:

* [DNAnexus](https://www.dnanexus.com/)
* [Terra](https://terra.bio/)
* [Nextflow](https://nextflow.io/)
* [Cromwell](https://cromwell.readthedocs.io/)
* [CWLtool](https://github.com/common-workflow-language/cwltool)

## Example Workflow

Our example workflow `02_download_collection_files` demonstrates how to query and download 10 files from any collection in a Viral AI instance. You can find this and othe [examples](https://github.com/DNAstack/dnastack-client-library-worked-examples/tree/master/examples) in the [DNAstack Client Library worked examples Github repo](https://github.com/DNAstack/dnastack-client-library-worked-examples).

The workflow is available in multiple formats:

* [Workflow Descriptor Language (WDL)](https://openwdl.org/)
* [Common Workflow Language (CWL)](https://www.commonwl.org/)
* [Nextflow](https://www.nextflow.io/)

Proceed to the next section to learn how to run our WDL workflow on various platforms.
