First, you need setup a dev environment.
You can then clone the app repository and install dependencies:
$ git clone https://github.com/cozy/cozy-home.git
$ cd cozy-home
$ yarn install
$ yarn startIf you want to simulate flagship environment, you can add the PUBLIC_SIMULATE_FLAGSHIP=true var and uncomment code in index.ejs before running yarn build. It'll simulate a splashscreen during the loading of the application and simulate a call to hideSplashscreen.
