## Commercial Usage
|
||||
|
||||
React Flow includes a small attribution that links to the React Flow website. **We expect companies who are using React Flow commercially to subscribe to [React Flow Pro](https://pro.reactflow.dev/pricing) if they want to remove the attribution.** By subscribing you get access to other exclusive services like advanced examples, individual support or prioritized bug reports. In non-commercial applications you may hide the attribution without subscribing but are welcome to [sponsor us on Github](https://github.com/sponsors/wbkd).
|
||||
**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 🌟
|
||||
|
||||
You can find more information in our [React Flow Pro FAQs](https://pro.reactflow.dev/faq).
|
||||
**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://pro.reactflow.dev) or through [Github Sponsors](https://github.com/sponsors/wbkd).

## Development
|
||||
|
||||
Before you start you need to build the project using `npm run build`. Then install the React Flow dependencies via `npm install` and the ones of the examples `cd example && npm install`.
|
||||
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`.
|
||||
|
||||
If you want to contribute or develop custom features the easiest way is to start the dev server:
|
||||
|
||||
```sh
|
||||
npm start
|
||||
```
|
||||
|
||||
and the example app via:
|
||||
|
||||
```sh
|
||||
cd example && npm start
|
||||
```
|
||||
|
||||
The example app serves the content of the `example` folder and watches changes inside the `src` folder. The examples are using the source of the `src` folder.
|
||||
For local development, you can use `pnpm dev`.
|
||||
|
||||
## Testing
