 **aws.iam** is a simple client package for the Amazon Web Services (AWS) [Identity and Access Management (IAM)](http://aws.amazon.com/iam/) and [Simple Token Service (STS)](http://docs.aws.amazon.com/STS/latest/APIReference) API, which can be used to manage access credentials for AWS services.
 
-To use the package, you will need an AWS account and enter your credentials into R. Your keypair can be generated on the [IAM Management Console](https://aws.amazon.com/) under the heading *Access Keys*. Note that you only have access to your secret key once. After it is generated, you need to save it in a secure location. New keypairs can be generated at any time if yours has been lost, stolen, or forgotten. 
-
-By default, all **cloudyr** packages look for the access key ID and secret access key in environment variables. You can also use this to specify a default region or a temporary "session token". For example:
-
-```R
-Sys.setenv("AWS_ACCESS_KEY_ID" = "mykey",
-           "AWS_SECRET_ACCESS_KEY" = "mysecretkey",
-           "AWS_DEFAULT_REGION" = "us-east-1",
-           "AWS_SESSION_TOKEN" = "mytoken")
-```
-
-These can alternatively be set on the command line prior to starting R or via an `Renviron.site` or `.Renviron` file, which are used to set environment variables in R during startup (see `? Startup`).
-
-If you work with multiple AWS accounts, another option that is consistent with other Amazon SDKs is to create [a centralized `~/.aws/credentials` file](https://blogs.aws.amazon.com/security/post/Tx3D6U6WSFGOK2H/A-New-and-Standardized-Way-to-Manage-Credentials-in-the-AWS-SDKs), containing credentials for multiple accounts.

+aws.signature::use_credentials(profile = "bob")

+
+Temporary session tokens are stored in environment variable `AWS_SESSION_TOKEN` (and will be stored there by the `use_credentials()` function). The [aws.iam package](https://github.com/cloudyr/aws.iam/) provides an R interface to IAM roles and the generation of temporary session tokens via the security token service (STS).
