Before you can begin using ec2u, you must set up authentication credentials. If you have the AWS CLI installed, then you can use it to configure your credentials file:

aws configure 

Alternatively, you can create the credential file yourself. By default, its location is at ~/.aws/credentials:

[default]
aws_access_key_id = YOUR_ACCESS_KEY
aws_secret_access_key = YOUR_SECRET_KEY

You may also want to set a default region. This can be done in the configuration file. By default, its location is at ~/.aws/config:

[default]
region=us-east-1

This sets up credentials for the default profile as well as a default region to use when creating connections. See Credentials for in-depth configuration sources and options.
