+## Quickstart
+
+Create the BlobServiceClient
+```php
+$blobServiceClient = BlobServiceClient::fromConnectionString("<connection string>");
+```
+
+Create a container
+```php
+$containerClient = $blobServiceClient->getContainerClient('quickstart');
+$containerClient->create();
+```
+
+List containers in a storage account
+```php
+$containers = $blobServiceClient->getBlobContainers();
+```
+
+Upload a blob to a container
+```php
+$blobClient = $containerClient->getBlobClient("hello.txt");
+$blobClient->upload("world!");
+
+// or using streams
+$file = fopen('hugefile.txt', 'r');
+$blobClient->upload($file);
+```
+
+List blobs in a container
+```php
+$blobs = $containerClient->getBlobs();
+
+// or with a prefix
+$blobs = $containerClient->getBlobs('some/virtual/directory');
+
+// and if you want both the blobs and virtual directories
+$blobs = $containerClient->getBlobsByHierarchy('some/virtual/directory');
+```
+
+Download a blob
+```php
+$result = $blobClient->downloadStreaming();
+
+$props = $result->properties;
+$content = $result->content->getContents();
+```
+
+Copy a blob
+```php
+$sourceBlobClient = $containerClient->getBlobClient("source.txt");
+
+// Can also be a different container
+$targetBlobClient = $containerClient->getBlobClient("target.txt");
+$targetBlobClient->copyFromUri($sourceBlobClient->uri);
+```
+
+Generate and use a [Service SAS](https://learn.microsoft.com/en-us/azure/storage/common/storage-sas-overview#service-sas)
+```php
+$sas = $blobClient->generateSasUri(
+    BlobSasBuilder::new()
+        ->setPermissions(new BlobSasPermissions(read: true))
+        ->setExpiresOn((new \DateTime())->modify("+ 15min")),
+);
+
+$sasBlobClient = new BlobClient($sas);
+```
+
+Generate and use an [Account SAS](https://learn.microsoft.com/en-us/azure/storage/common/storage-sas-overview#account-sas)
+```php
+$sas = $blobServiceClient->generateAccountSasUri(
+    AccountSasBuilder::new()
+        ->setPermissions(new AccountSasPermissions(list: true))
+        ->setResourceTypes(new AccountSasResourceTypes(service: true))
+        ->setExpiresOn((new \DateTime())->modify("+ 15min")),
+);
+
+$sasServiceClient = new BlobServiceClient($sas);
+```
+
+Delete a container
+```php
+$containerClient->delete();
+```
