+
+## Getting started
+
+### Prerequisites
+
+- [Java Development Kit (JDK)][jdk] with version 8 or above
+- [Azure Subscription][azure_subscription]
+- [Create Storage Account][storage_account]
+
+### Adding the package to your product
+
+[//]: # ({x-version-update-start;com.azure:azure-storage-blob-nio;current})
+```xml

+    <groupId>com.azure</groupId>

+```
+[//]: # ({x-version-update-end})
+
+### Default HTTP Client
+All client libraries, by default, use the Netty HTTP client. Adding the above dependency will automatically configure 
+Storage Blob to use the Netty HTTP client. 
+
+### Alternate HTTP client
+If, instead of Netty it is preferable to use OkHTTP, there is an HTTP client available for that too. Exclude the default
+Netty and include the OkHTTP client in your pom.xml.
+
+[//]: # ({x-version-update-start;com.azure:azure-storage-blob;current})

+
+### Configuring HTTP Clients
+When an HTTP client is included on the classpath, as shown above, it is not necessary to specify it in the client library [builders](#create-blobserviceclient) unless you want to customize the HTTP client in some fashion. If this is desired, the `httpClient` builder method is often available to achieve just this by allowing users to provide custom (or customized) `com.azure.core.http.HttpClient` instances.
+
+For starters, by having the Netty or OkHTTP dependencies on your classpath, as shown above, you can create new instances of these `HttpClient` types using their builder APIs. For example, here is how you would create a Netty HttpClient instance:
+
+### Default SSL library
+All client libraries, by default, use the Tomcat-native Boring SSL library to enable native-level performance for SSL operations. The Boring SSL library is an uber jar containing native libraries for Linux / macOS / Windows, and provides better performance compared to the default SSL implementation within the JDK. For more information, including how to reduce the dependency size, refer to the [performance tuning][performance_tuning] section of the wiki.
+
+```java
+HttpClient client = new NettyAsyncHttpClientBuilder()
+        .port(8080)
+        .wiretap(true)
+        .build();
+```
+
+### Create a Storage Account
+To create a Storage Account you can use the [Azure Portal][storage_account_create_portal] or [Azure CLI][storage_account_create_cli].
+
+```bash
+az storage account create \
+    --resource-group <resource-group-name> \
+    --name <storage-account-name> \
+    --location <location>
+```
+
+### Authenticate the client
+
+In order to interact with the Storage Service (Blob, Queue, Message, MessageId, File) you'll need to create an instance of the Service Client class.
+To make this possible you'll need the Account SAS (shared access signature) string of the Storage Account. Learn more at [SAS Token][sas_token]
+
+#### Get credentials
+
+##### SAS Token
+
+a. Use the Azure CLI snippet below to get the SAS token from the Storage Account.
+
+```bash
+az storage blob generate-sas \
+    --account-name {Storage Account name} \
+    --container-name {container name} \
+    --name {blob name} \
+    --permissions {permissions to grant} \
+    --expiry {datetime to expire the SAS token} \
+    --services {storage services the SAS allows} \
+    --resource-types {resource types the SAS allows}
+```
+
+Example:
+
+```bash
+CONNECTION_STRING=<connection-string>
+
+az storage blob generate-sas \
+    --account-name MyStorageAccount \
+    --container-name MyContainer \
+    --name MyBlob \
+    --permissions racdw \
+    --expiry 2020-06-15
+```
+
+b. Alternatively, get the Account SAS Token from the Azure Portal.
+
+1. Go to your Storage Account
+2. Select `Shared access signature` from the menu on the left
+3. Click on `Generate SAS and connection string` (after setup)
+
+##### **Shared Key Credential**
+
+a. Use Account name and Account key. Account name is your Storage Account name.
+
+1. Go to your Storage Account
+2. Select `Access keys` from the menu on the left
+3. Under `key1`/`key2` copy the contents of the `Key` field
+
+or
+
+b. Use the connection string.
+
+1. Go to your Storage Account
+2. Select `Access keys` from the menu on the left
+3. Under `key1`/`key2` copy the contents of the `Connection string` field
+
+## Key concepts
+
+Blob Storage is designed for:
+
+- Serving images or documents directly to a browser
+- Storing files for distributed access
+- Streaming video and audio
+- Writing to log files
+- Storing data for backup and restore, disaster recovery, and archiving
+- Storing data for analysis by an on-premises or Azure-hosted service
+
+## Examples
+
+The following sections provide several code snippets covering some of the most common Azure Storage Blob tasks, including:
+
+- [Create a `BlobServiceClient`](#create-a-blobserviceclient)
+
+
+### Create a `BlobServiceClient`
+
+Create a `BlobServiceClient` using the [`sasToken`](#get-credentials) generated above.
+
+```java
+BlobServiceClient blobServiceClient = new BlobServiceClientBuilder()
+        .endpoint("<your-storage-blob-url>")
+        .sasToken("<your-sasToken>")
+        .buildClient();
+```
+
+
+## Troubleshooting
+
+When interacting with blobs using this Java client library, errors returned by the service correspond to the same HTTP
+status codes returned for [REST API][error_codes] requests. For example, if you try to retrieve a container or blob that
+doesn't exist in your Storage Account, a `404` error is returned, indicating `Not Found`.
+
+## Next steps
+
+Several Storage blob Java SDK samples are available to you in the SDK's GitHub repository. These samples provide example code for additional scenarios commonly encountered while working with Key Vault:
+
+## Next steps Samples
+Samples are explained in detail [here][samples_readme].
