 #### Creating a Custom Permission Dependency
 
-Any class implements the `IPermissionStateProvider` interface can disable a permission based on a custom condition.
-
-**Example:**
-
-````csharp
-public class MyCustomPermissionStateProvider : IPermissionStateProvider
-{
-    public Task<bool> IsEnabledAsync(PermissionStateContext context)
-    {
-        // You can implement your own logic here. 
-        return Task.FromResult(
-            context.Permission.Name.StartsWith("Acme.BookStore"));
-    }
-}
-````
-
-Then you can add `MyCustomPermissionStateProvider` to any permission definition, using the `AddStateProviders` extension method:
-
-````csharp
-myGroup.AddPermission("Book_Creation")
-    .AddStateProviders(new MyCustomPermissionStateProvider());
-````
-
-Or you can globally add your custom provider to make it working for all permissions:
-
-````csharp
-Configure<AbpPermissionOptions>(options =>
-{
-	options.GlobalStateProviders.Add<MyCustomPermissionStateProvider>();
-});
-````
+`PermissionDefinition` supports state check, Please refer to [Simple State Checker's documentation](SimpleStateChecker.md)

+# Simple State Checker
+
+The simple state checking system can be used to enable/disable an object based on some dynamic conditions. For example, you can disable a menu item on the user interface, if the current user has not granted for a given permission. The simple state checking system provides a generic way to define and check such conditions.
+
+## Definition state checker.
+
+Any class can inherit `IHasSimpleStateCheckers` to support state checks.
+
+````csharp
+public class MyObject : IHasSimpleStateCheckers<MyObject>
+{
+    public int Id { get; set; }
+
+    public List<ISimpleStateChecker<MyObject>> SimpleStateCheckers { get; }
+
+    public MyObject()
+    {
+        SimpleStateCheckers = new List<ISimpleStateChecker<MyObject>>();
+    }
+}
+````
+
+The `MyObject` class contains a collection of state checkers, you can add your custom checkers to it.
+
+````csharp
+public class MyObjectStateChecker : ISimpleStateChecker<MyObject>
+{
+    public Task<bool> IsEnabledAsync(SimpleStateCheckerContext<MyObject> context)
+    {
+        var currentUser = context.ServiceProvider.GetRequiredService<ICurrentUser>();
+        return Task.FromResult(currentUser.IsInRole("Admin"));
+    }
+}
+````
+
+````csharp
+var myobj = new MyObject()
+{
+    Id = 100
+};
+
+myobj.SimpleStateCheckers.Add(new MyObjectStateChecker());
+````
+
+## Definition Global State Checkers
+
+`AbpSimpleStateCheckerOptions` is the options class that used to set the global state checkers for specific object.
+
+Example: Add global state for `MyObject`:
+
+````csharp
+services.Configure<AbpSimpleStateCheckerOptions<MyObject>>(options =>
+{
+    options.GlobalSimpleStateCheckers.Add<MyGlobalObjectStateChecker>();
+    //options.GlobalSimpleStateCheckers.Add<>(); //Add more global state checkers
+});
+````
+
+> Write this inside the `ConfigureServices` method of your module.
+
+## Check the state
+
+You can inject `ISimpleStateCheckerManager<MyObject>` service to check state.
+
+````csharp
+bool enabled = await stateCheckerManager.IsEnabledAsync(myobj);
+````
+
+### Batch check the states
+
+If there are many instance items that require state checking, there may be performance problems.
+
+In this case, you can implement `ISimpleBatchStateChecker`. It can check multiple items at once.
+You need to make sure that the same `ISimpleBatchStateChecker` instance is added to the `SimpleStateCheckers` of multiple instances.
+
+> `SimpleBatchStateCheckerBase` inherits the `ISimpleBatchStateChecker` interface and implements the `IsEnabledAsync` method of a single object by default.
+
+````csharp
+public class MyObjectBatchStateChecker : SimpleBatchStateCheckerBase<MyObject>
+{
+    public override Task<SimpleStateCheckerResult<MyObject>> IsEnabledAsync(SimpleBatchStateCheckerContext<MyObject> context)
+    {
+        var result = new SimpleStateCheckerResult<MyObject>(context.States);
+
+        foreach (var myObject in context.States)
+        {
+            if (myObject.Id > 100)
+            {
+                result[myObject] = true;
+            }
+        }
+
+        return Task.FromResult(result);
+    }
+}
+````
+
+````csharp
+var myobj1 = new MyObject()
+{
+    Id = 100
+};
+var myobj2 = new MyObject()
+{
+    Id = 99
+};
+
+var myObjectBatchStateChecker = new MyObjectBatchStateChecker();
+
+myobj1.SimpleStateCheckers.Add(myObjectBatchStateChecker);
+myobj2.SimpleStateCheckers.Add(myObjectBatchStateChecker);
+
+SimpleStateCheckerResult<MyObject> stateCheckerResult = await stateCheckerManager.IsEnabledAsync(new []{ myobj1, myobj2 });
+````
+
+## Built-in State Checkers
+
+The `PermissionDefinition`, `ApplicationMenuItem` and `ToolbarItem` objects have implemented state checks and have built-in general state checkers, you can directly use their extension methods.
+
+````csharp
+RequireAuthenticated();
+RequirePermissions(bool requiresAll, params string[] permissions);
+RequireFeatures(bool requiresAll, params string[] features);
+RequireGlobalFeatures(bool requiresAll, params Type[] globalFeatures);
+````
