+# AWS Encryption SDK for JavaScript client for the Browser

+
+The *client-browser* module includes all of the modules you need to use the AWS Encryption SDK for
+the JavaScript web browser.
+
+* decrypt-browser
+* encrypt-browser
+* kms-keyring-browser
+* material-management-browser
+* caching-materials-manager-browser
+* raw-aes-keyring-browser
+* raw-rsa-keyring-browser
+
+For code examples that show you how to these modules to create keyrings and encrypt and decrypt data, install the [example-browser](https://github.com/awslabs/aws-encryption-sdk-javascript/tree/master/modules/example-browser) module. 
+## install
+
+To install this module, use the npm package manager. For help with installation, see
+[https://www.npmjs.com/get-npm](https://www.npmjs.com/get-npm). 
+
+```sh
+npm install @aws-crypto/client-browser
+```
+
+## use
+
+```javascript
+
+/* Start by constructing a keyring. We'll create a KMS keyring.
+ * Specify an AWS Key Management Service (AWS KMS) customer master key (CMK) to be the
+ * generator key in the keyring. This CMK generates a data key and encrypts it. 
+ * To use the keyring to encrypt data, you need kms:GenerateDataKey permission 
+ * on this CMK. To decrypt, you need kms:Decrypt permission. 
+ */
