brew update
brew upgrade
# Now install nodejs
brew install nodejs
# Because it is a react-native app, we need react-native
npm install react-native-cli -g
# The next thing to do is: Go clone this repo and move into it with cd
# Install dependencies with npm
npm install
# Because I didn't uploaded the ios folder, you need to create it
react-native eject
# Link all native dependencies
react-native link
# You are ready, go into the ios folder and open the xcode project and build the app.
