 This command gets a single blob with blob tag condition. 
 The cmdlet will only success when the blob contains a tag with name "tag1" and value "value1", else the cmdlet will fail with error code 412.
 
+### Example 10: Get blob properties (example: ImmutabilityPolicy) of a single blob
+```powershell
+$blobProperties = (Get-AzStorageBlob -Container "ContainerName" -Blob "blob" -Context $ctx).BlobProperties
+$blobProperties.ImmutabilityPolicy
+```

+This example command gets the immutability property of a single blob. You can get a detailed list of blob prTooperties from the **BlobProperties** property, including but not limited to: LastModified, ContentLength, ContentHash, BlobType, LeaseState, AccessTier, ETag, ImmutabilityPolicy, etc...
+To list multiple blobs (execute the cmdlet without blob name), use **ListBlobProperties.Properties** instead of **BlobProperties** for better performance.
