-## Azure Core Authentication
+# Azure Core Authentication client library for JavaScript
 
-This library provides core interfaces and helper methods for authenticating with Azure services using Azure Active Directory and other authentication schemes common across the Azure SDK. As a "core" library, it shouldn't need to be added as a dependency to any user code, only other Azure SDK libraries.
+The `@azure/core-auth` package provides core interfaces and helper methods for authenticating with Azure services using Azure Active Directory and other authentication schemes common across the Azure SDK. As a "core" library, it shouldn't need to be added as a dependency to any user code, only other Azure SDK libraries.
+
+## Getting started
+
+### Installation
+
+Install this library using npm as follows
+
+```
+npm install @azure/core-auth
+```
+
+## Key Concepts
+
+The `TokenCredential` interface represents a credential capable of providing an authentication token. The `@azure/identity` package contains various credentials that implement the `TokenCredential` interface.
+
+The `AzureKeyCredential` is a static key-based credential that supports key rotation via the `update` method. Use this when a single secret value is needed for authentication, e.g. when using a shared access key.
+
+The `AzureNamedKeyCredential` is a static name/key-based credential that supports name and key rotation via the `update` method. Use this when both a secret value and a label are needed, e.g. when using a shared access key and shared access key name.
+
+The `AzureSASCredential` is a static signature-based credential that supports updating the signature value via the `update` method. Use this when using a shared access signature.
+
+## Examples
+
+### AzureKeyCredential
+
+```js
+const { AzureKeyCredential } = require("@azure/core-auth");
+
+const credential = new AzureKeyCredential("secret value");
+// prints: "secret value"
+console.log(credential.key);
+credential.update("other secret value");
+// prints: "other secret value"
+console.log(credential.key);
+```
+
+### AzureNamedKeyCredential
+
+```js
+const { AzureNamedKeyCredential } = require("@azure/core-auth");
+
+const credential = new AzureNamedKeyCredential("ManagedPolicy", "secret value");
+// prints: "ManagedPolicy, secret value"
+console.log(`${credential.name}, ${credential.key}`);
+credential.update("OtherManagedPolicy", "other secret value");
+// prints: "OtherManagedPolicy, other secret value"
+console.log(`${credential.name}, ${credential.key}`);
+```
+
+### AzureSASCredential
+
+```js
+const { AzureSASCredential } = require("@azure/core-auth");
+
+const credential = new AzureSASCredential("signature1");
+// prints: "signature1"
+console.log(credential.signature);
+credential.update("signature2");
+// prints: "signature2"
+console.log(credential.signature);
+```
