Use when asking about the main argoproj feature, Argo Workflows. github.com/argoproj/argo-workflows

Argo Workflows facilitates executing a set of actions in Kubernetes. Workflows are implemented as Kubernetes Custom Resource Definitions (CRDs). The actions may be defined by connecting "steps" or by describing a directed acyclic graph (DAG).

Argo was originally developed by Applatix and then was acquired and maintained by Intuit. It is now a Cloud Native Computing Foundation (CNCF) incubation-level project.
