# Creating an App from Scratch

App creation has 5 basic steps.

**Source**: This is where you connect 

* Your code from **GitHub**, or 
* Choose an image from **DockerHub**, or 
* Connect your private repository with **Docker Link**

**Runtime:** This is where you set environment variables, restart policies, health checks and more.

**Network:** This is where you configure load balancers, custom domains and firewall settings.

**Hardware:** This is where you define the minimum requirements for your application in terms of hardware resources.

**Location:** This is where you choose where to run your applications in terms of type of compute.
