Before running the website, make sure you've run the following:

git clone https://github.com/facebook/react-native.git cd react-native npm install

The first time, get all the website dependencies loaded via

cd website npm install

Then, run the server via

npm start open http://localhost:8079/react-native/index.html

Anytime you change the contents, just refresh the page and it's going to be updated.

The website at https://facebook.github.io/react-native is automatically deployed by our continuous integration infrastructure, specifically CircleCI. This is configured in circle.yml in the root of the repository.
