+## 🚨 Upcoming Changes 
+
+The main branch is the home of @xyflow/svelte and the upcoming @xyflow/react (React Flow v12). The current version is maintained and lives on the [v11 branch](https://github.com/xyflow/xyflow/tree/v11).
+
+
+## Key Features
+
+- **Easy to use:** Seamless zooming and panning, single- and multi selection of graph elements and keyboard shortcuts are supported out of the box
+- **Customizable:** Different [node](https://reactflow.dev/examples) and [edge types](https://reactflow.dev/examples/edges/edge-types) and support for custom nodes with multiple handles and custom edges
+- **Fast rendering:** Only nodes that have changed are re-rendered 
+- **Hooks and Utils:** [Hooks](https://reactflow.dev/api-reference/hooks) for handling nodes, edges and the viewport and graph [helper functions](https://reactflow.dev/api-reference/utils)
+- **Plugin Components:** [Background](https://reactflow.dev/api-reference/components/background), [MiniMap](https://reactflow.dev/api-reference/components/minimap) and [Controls](https://reactflow.dev/api-reference/components/controls)
+- **Reliable**: Written in [Typescript](https://www.typescriptlang.org/) and tested with [cypress](https://www.cypress.io/)
+
+## Commercial Usage
+
+**Are you using React Flow for a personal project?** Great! No sponsorship needed, you can support us by reporting any bugs you find, sending us screenshots of your projects, and starring us on Github 🌟
+
+**Are you using React Flow at your organization and making money from it?** Awesome! We rely on your support to keep React Flow developed and maintained under an MIT License, just how we like it. You can do that on the [React Flow Pro website](https://reactflow.dev/pro) or through [Github Sponsors](https://github.com/sponsors/xyflow).
+
+You can find more information in our [React Flow Pro FAQs](https://reactflow.dev/pro).
+
+
+## Installation
+
+The easiest way to get the latest version of React Flow is to install it via npm, yarn or pnpm:
+
+```bash
+npm install reactflow
+```
+
+## Quick Start
+
+This is only a very basic usage example of React Flow. To see everything that is possible with the library, please refer to the [website](https://reactflow.dev) for [guides](https://reactflow.dev/learn/customization/custom-nodes), [examples](https://reactflow.dev/examples) and the full [API reference](https://reactflow.dev/api-reference/react-flow).
+
+```jsx
+import { useCallback } from 'react';
+import ReactFlow, {
+  MiniMap,
+  Controls,
+  Background,
+  useNodesState,
+  useEdgesState,
+  addEdge,
+} from 'reactflow';
+
+import 'reactflow/dist/style.css';
+
+const initialNodes = [
+  { id: '1', position: { x: 0, y: 0 }, data: { label: '1' } },
+  { id: '2', position: { x: 0, y: 100 }, data: { label: '2' } },
+];
+
+const initialEdges = [{ id: 'e1-2', source: '1', target: '2' }];
+
+function Flow() {
+  const [nodes, setNodes, onNodesChange] = useNodesState(initialNodes);
+  const [edges, setEdges, onEdgesChange] = useEdgesState(initialEdges);
+
+  const onConnect = useCallback((params) => setEdges((eds) => addEdge(params, eds)), [setEdges]);
+
+  return (
+    <ReactFlow
+      nodes={nodes}
+      edges={edges}
+      onNodesChange={onNodesChange}
+      onEdgesChange={onEdgesChange}
+      onConnect={onConnect}
+    >
+      <MiniMap />
+      <Controls />
+      <Background />
+    </ReactFlow>
+  );
+}
+```
+
+## Development
+
+Before you can start developing please make sure that you have [pnpm](https://pnpm.io/) installed (`npm i -g pnpm`). Then install the dependencies using pnpm: `pnpm install`.
+
+For local development, you can use `pnpm dev`.
+
+## Testing
+
+Testing is done with cypress. You can find the tests in the [`examples/cypress`](/examples/cypress/) folder. In order to run the tests do:
+
+```sh
+pnpm test
+```
+

+## Community Packages
+
+- [useUndoable](https://github.com/Infinium8/useUndoable) - Hook for undo/redo functionality with an explicit React Flow example
+- [react-flow-smart-edge](https://github.com/tisoap/react-flow-smart-edge) - Custom edge that doesn't intersect with nodes
+- [Feliz.ReactFlow](https://github.com/tforkmann/Feliz.ReactFlow) - Feliz React Bindings for React Flow
+
+## Credits
+
+React Flow was initially developed for [datablocks](https://datablocks.pro), a graph-based editor for transforming, analyzing and visualizing data in the browser. Under the hood, React Flow depends on these great libraries:
+
+- [d3-zoom](https://github.com/d3/d3-zoom) - used for zoom, pan and drag interactions with the graph canvas
+- [d3-drag](https://github.com/d3/d3-drag) - used for making the nodes draggable
+- [zustand](https://github.com/pmndrs/zustand) - internal state management
