 ### Setting Up the Environment
 Before running the samples, make sure that your environment is configured to allow the samples to use your [AWS Security Credentials](http://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html), which are used by [MultiLangDaemon][multi-lang-daemon] to interact with AWS services.
 
-By default, the [MultiLangDaemon][multi-lang-daemon] uses the [DefaultAWSCredentialsProviderChain][DefaultAWSCredentialsProviderChain], so make your credentials available to one of the credentials providers in that provider chain. There are several ways to do this. You can provide credentials through a `~/.aws/credentials` file or through environment variables (**AWS\_ACCESS\_KEY\_ID** and **AWS\_SECRET\_ACCESS\_KEY**). If you're running on Amazon EC2, you can associate an IAM role with your instance with appropriate access.
