 ## Key concepts
-The Azure Storage platform is Microsoft's cloud storage solution for modern data storage scenarios. Core storage services offer a massively scalable object store for data objects, disk storage for Azure virtual machines (VMs), a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store.

 #### Autowire a resource 
-You can use the annotation of `@Value("blob://{containerName}/{blobName}")` to autowire a `Resource` with that in [Azure Blob storage][azure_storage].
+You can use the annotation of `@Value("azure-blob://[your-container-name]/[your-blob-name]")` to autowire a **blob** `Resource`.
 
 ```java
-@Value("blob://{containerName}/{blobName}")
-private Resource blobFile;

 #### Read and write to a resource 
  You can read a resource from Azure Blob storage with `getInputStream()` method.
 
 ```java
- this.blobFile.getInputStream();
+ this.storageResource.getInputStream();
 ```
 You can write to a resource in Azure Blob storage by casting the Spring `Resource` to `WritableResource`. 
 
 ```java
-(WritableResource) this.blobFile).getOutputStream();
+ ((WritableResource) this.azureBlobResource).getOutputStream();
 ```
