 ## Features
 
+### Resource Explorer
+
 The AWS Backend Explorer gives you a view of the AWS resources in Amplify Sandbox environment that you can work with when using the AWS Backend Explorer.You can open the AWS Resource page of your choice in the AWS Console of your browser.

+#### Filter resources
+
+You can filter resources in the AWS Resource Explorer.
+You can then switch which filter to use with the filter switching action.
+In addition, in `settings.json` you can define custom filters with a pair of names and an array of AWS resources in the tree, as shown below.
+
+```json
+{
+  "amplifyBackend.explorerFilters": [
+    {
+      "name": "simple",
+      "resources": [
+        "AWS::AppSync::GraphQLApi",
+        "Custom::AmplifyDynamoDBTable",
+        "AWS::Lambda::Function",
+        "AWS::S3::Bucket"
+      ]
+    }
+  ]
+}
+```
+
+#### Switch AWS Profile
+
 You can switch AWS Profile to explor the AWS resources.
