A small example of using AWS CloudFormation to set up an EC2 instance in a private network (VPC).

1. You need to have an AWS account set up.
2. The AWS SDK for Python Boto3 needs to be installed. This can be done from the repo or via a software like pip.
3. The above SDK needs to be configured to your AWS account credentials (instructions in the repo README).

1. tmpl.json describes the configuration of the EC2 instance. It must be stored in an AWS S3 bucket as an object - you need the URL of this object.
2. A public-private key pair needs to be created. Information here. You need the name of this key pair.
3. Using the URL from 1 and the key pair name from 2, you can use the function from setup.py. See the example function call in that file.
4. Feel free to modify tmpl.json to modify or add more features to your CloudFormation stack.
