 ## What is Argo Workflows?
-Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. Argo Workflows is implemented as a Kubernetes CRD (Custom Resource Definition).

 * Define workflows where each step in the workflow is a container.
-* Model multi-step workflows as a sequence of tasks or capture the dependencies between tasks using a directed acyclic graph (DAG).
-* Easily run compute intensive jobs for machine learning or data processing in a fraction of the time using Argo Workflows on Kubernetes.
-* Run CI/CD pipelines natively on Kubernetes without configuring complex software development products.

+## Use Cases
+
+* Machine Learning pipelines
+* Data and batch processing
+* ETL
+* Infrastructure automation
+* CI/CD
+
 ## Why Argo Workflows?
-* Designed from the ground up for containers without the overhead and limitations of legacy VM and server-based environments.
+
+* Argo Workflows is the most popular workflow execution engine for Kubernetes.
+* It can run 1000s of workflows a day, each with 1000s of concurrent tasks.
+* Our users say it is lighter-weight, faster, more powerful, and easier to use
+* Designed from the ground up for containers without the overhead and limitations of legacy VM and server-based
+  environments.
 * Cloud agnostic and can run on any Kubernetes cluster.
-* Easily orchestrate highly parallel jobs on Kubernetes.
-* Argo Workflows puts a cloud-scale supercomputer at your fingertips!
