7 Arvados Composer is a single-page javascript application for building Common Workflow Languge (CWL) Workflows.
11 In addition to Arvados core services, Composer requires "Arvados hosted git repositories":install-arv-git-httpd.html which are used for storing workflow files.
15 Composer may be installed on the same host as Workbench, or on a different host. Composer communicates directly with the Arvados API server. It does not require its own backend and should be served as a static file.
