Installation
1. Add Database, Social & Mailgun Settings
Navigate to the folder where you downloaded Gravity and open the .env & /config/default.json files located in the /server folder and then populate your database and Mailgun credentials.
If you're on the Power plan, you can use the setup wizard included with the React web client.
To use social sign-ons you must add your Facebook and Twitter API keys to the .env file and also the callback URLs to /config. See the section on Social Sign-Ons for more information.
You must complete this step before proceeding.
2. Install Expo
The Expo CLI will enable you to perform various Expo tasks, like running and building your app.
3. Download the Expo Mobile Client
On your iOS or Android mobile device, visit the respective app store, download the Expo mobile client then register a free account.
4. Install Gravity Native

5. Install ngrok (optional)
If you want to use social sign-ons in your application, you must install ngrok to handle the redirects.
Once installed, please update the callback_url inside the /config folder files and also the baseURL value inside app/config.json
