+
+🌊 is a simple, lightweight workflow engine, in TypeScript.
+
+### First, define events
+
+```ts
+import { workflowEvent } from "@llamaindex/workflow-core";
+
+const startEvent = workflowEvent<string>();
+const stopEvent = workflowEvent<1 | -1>();
+```
+
+### Connect events with workflow
+
+```ts
+import { createWorkflow } from "@llamaindex/workflow-core";
+
+const convertEvent = workflowEvent();
+
+const workflow = createWorkflow();
+
+workflow.handle([startEvent], (start) => {
+  return convertEvent.with(Number.parseInt(start.data, 10));
+});
+workflow.handle([convertEvent], (convert) => {
+  return stopEvent.with(convert.data > 0 ? 1 : -1);
+});
+```
+
+### Trigger workflow
+
+```ts
+import { pipeline } from "node:stream/promises";
+
+const { stream, sendEvent } = workflow.createContext();
+sendEvent(startEvent.with());
+const allEvents = await stream.until(stopEvent).toArray();
+```
