-#### *compile*
-Providers use **Google Auto** to generate services
+###### ComputeService
 
-**It is important to do like this**
-> mvn clean compile
+    ComputeService computeService;
+    String provider = "aliyun-ecs";
+    String key = "Your AccessKey";
+    String secret = "Your AccessKeySecret";
+    ComputeServiceContext context = ContextBuilder
+          .newBuilder(provider)
+          .credentials(key, secret)
+          .buildView(ComputeServiceContext.class);
+    computeService = context.getComputeService();
 
-Then you will find an folder named services from target\classes\META-INF in each modules
+###### BlobStore
 
-If you do not do the operation, an error will happends.
+    BlobStore blobStore;
+    String provider = "aliyun-oss";
+    String key = "Your AccessKey";
+    String secret = "Your AccessKeySecret";
+    BlobStoreContext context = ContextBuilder
+          .newBuilder(provider)
+          .credentials(key, secret)
+          .buildView(BlobStoreContext.class);
+    blobStore = context.getBlobStore();
 
-    key [aliyun-ecs] not in the list of providers or apis
+###### LoadBalancerService
 
-#### *test*
-Please change the accessKey and secret witch generate by your own account of [Aliyun](http://www.aliyun.com) in each test classes before test
+    LoadBalancerService loadBalancerService;
+    String provider = "aliyun-slb";
+    String key = "Your AccessKey";
+    String secret = "Your AccessKeySecret";
+    LoadBalancerServiceContext context = ContextBuilder
+          .newBuilder(provider)
+          .credentials(key, secret)
+          .buildView(LoadBalancerServiceContext.class);
+    loadBalancerService = context.getLoadBalancerService();
 
-    private static final String key = "nyCUviU59zdxOIYJ";
-    private static final String secret = "VX99Yry885o0lpjFgzIpjibrVJIGgB";
+### Build
 
-Then run command
-> mvn test
+> mvn package -DskipTests
