 ## Template
 
+This is the template for challenger to start the coding, basically you just need to change the name of your generic/function and leave to implementation `any`.
+
 ```ts
 type YourType = any
 ```
 
 ## Test Cases
 
-```ts
-import { Equal, Expect } from '@type-challenges/utils'
+Provide some test cases for your challenge, you can use some utils from `@type-challenges/utils` for assetion.

+```ts
+import { Equal, Expect, ExpectFalse, NotEqual } from '@type-challenges/utils'
 
-// your test cases
 type cases = [
   Expect<Equal<true, true>>

+## 题目模版
+
+以下是给予挑战者开始做题的代码模版，在大部分情况下你只需要修改类型名称使其符合你的题目与判题测试，实现的部分保持 `any` 即可。
+
+```ts
+type YourType = any

+
+## 判题测试
+
+请为你的题目提供一些判题测试，你可以使用 `@type-challenges/utils` 中提供的一些工具进行判断。
+
+```ts
+import { Equal, Expect, ExpectFalse, NotEqual } from '@type-challenges/utils'
+
+type cases = [
+  Expect<Equal<true, true>>
