+k6 is a modern load-testing tool, built on our years of experience in
+the performance and testing industries. It's built to be powerful,
+extensible, and full-featured. The key design goal is to provide the
+best developer experience.
+
+Its core features are:
+
+- Configurable load generation. Even lower-end machines can simulate
+  lots of traffic.
+- Tests as code. Reuse scripts, modularize logic, version control, and
+  integrate tests with your CI.
+- A full-featured API. The scripting API is packed with features that
+  help you simulate real application traffic.
+- An embedded JavaScript engine. The performance of Go, the scripting
+  familiarity of JavaScript.
+- Multiple Protocol support. HTTP, WebSockets, gRPC, and more.
+- Large extension ecosystem. You can extend k6 to support your needs.
+  And many people have already shared their extensions with the
+  community!
+- Flexible metrics storage and visualization. Summary statistics or
+  granular metrics, exported to the service of your choice.
