-Workflows is a durable execution engine built on Cloudflare Workers. Workflows allow you to build multi-step applications that can automatically retry, persist state and run for minutes, hours, days, or weeks. Workflows introduces a programming model that makes it easier to build reliable, long-running tasks, observe as they progress, and programatically trigger instances based on events across your services.
-
-Refer to the [get started guide](/workflows/get-started/guide/) to start building with Workflows.
+With Workflows, you can build applications that chain together multiple steps, automatically retry failed tasks,
+and persist state for minutes, hours, or even weeks - with no infrastructure to manage.
+
+This gives you:
+
+- Reliable multi-step operations without worrying about timeouts
+- Automatic retries and error handling
+- Built-in observability for long running operations
+- Simple and expressive code for complex processes
