+    AWS Key Management Service
+    AWS Key Management Service (KMS) is an encryption and key
+    management web service. This guide describes the KMS actions that
+    you can call programmatically. For general information about KMS,
+    see (need an address here). For the KMS developer guide, see (need
+    address here).
+
+    AWS provides SDKs that consist of libraries and sample code for
+    various programming languages and platforms (Java, Ruby, .Net,
+    iOS, Android, etc.). The SDKs provide a convenient way to create
+    programmatic access to KMS and AWS. For example, the SDKs take
+    care of tasks such as signing requests (see below), managing
+    errors, and retrying requests automatically. For more information
+    about the AWS SDKs, including how to download and install them,
+    see `Tools for Amazon Web Services`_.
+
+    We recommend that you use the AWS SDKs to make programmatic API
+    calls to KMS. However, you can also use the KMS Query API to make
+    to make direct calls to the KMS web service.
+
+    **Signing Requests**
+
+    Requests must be signed by using an access key ID and a secret
+    access key. We strongly recommend that you do not use your AWS
+    account access key ID and secret key for everyday work with KMS.
+    Instead, use the access key ID and secret access key for an IAM
+    user, or you can use the AWS Security Token Service to generate
+    temporary security credentials that you can use to sign requests.
+
+    All KMS operations require `Signature Version 4`_.
+
+    **Recording API Requests**
+
+    KMS supports AWS CloudTrail, a service that records AWS API calls
+    and related events for your AWS account and delivers them to an
+    Amazon S3 bucket that you specify. By using the information
+    collected by CloudTrail, you can determine what requests were made
+    to KMS, who made the request, when it was made, and so on. To
+    learn more about CloudTrail, including how to turn it on and find
+    your log files, see the `AWS CloudTrail User Guide`_
+
+    **Additional Resources**
+
+    For more information about credentials and request signing, see
+    the following:
+
+
+    + `AWS Security Credentials`_. This topic provides general
+      information about the types of credentials used for accessing AWS.
+    + `AWS Security Token Service`_. This guide describes how to
+      create and use temporary security credentials.
+    + `Signing AWS API Requests`_. This set of topics walks you
+      through the process of signing a request using an access key ID
+      and a secret access key.
