 欢迎来到这里 ，  **Docusaurus in less than 1 minutes**.
 
-## Getting Started
+## 现在开始
 
 Get started by **creating a new site**.
 
 Or **try Docusaurus immediately** with **[new.docusaurus.io](https://new.docusaurus.io)**.
 
-## Generate a new site
+## 代码块
 
-Generate a new Docusaurus site using the **classic template**:
+
+
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+<Tabs
+defaultValue="js"
+values={[
+{ label: 'JavaScript', value: 'js', },
+{ label: 'Python', value: 'py', },
+{ label: 'Java', value: 'java', },
+]
+}>
+<TabItem value="js">
+
+```js
+function helloWorld() {
+  console.log('Hello, world!');
+}
+```
+
+</TabItem>
+<TabItem value="py">
+
+```py
+def hello_world():
+  print 'Hello, world!'
+```
+
+</TabItem>
+<TabItem value="java">
+
+```java
+class HelloWorld {
+  public static void main(String args[]) {
+    System.out.println("Hello, World");
+  }
+}
+```
+
+</TabItem>
+</Tabs>
+
+
+
+以上是一些语言的‘Hello World’
+
+JS**:
+```jsx title="/src/components/HelloCodeTitle.js"
+function HelloCodeTitle(props) {
+  return <h1>Hello, {props.name}</h1>;
+}
+```
+
+
+shell**:
 
 ```shell
 npx @docusaurus/init@latest init my-website classic
 ```
 
-## Start your site
+## 开启Code-Docs服务
 
 Run the development server:
 
-```shell
-cd my-website
-
-npx docusaurus start
-```
-
 Your site starts at `http://localhost:3000`.
 
-Open `docs/getting-started.md` and edit some lines: the site **reloads automatically** and display your changes.

+**Fundamental Theorem of Calculus**  
+Let $f:[a,b] \to \R$ be Riemann integrable. Let $F:[a,b]\to\R$ be $F(x)=
+\int_{a}^{x}f(t)dt$.
+Then $$F$$ is continuous, and at all $x$ such that $f$ is continuous at $x$,
+$F$ is differentiable at $x$ with $F'(x)=f(x)$.
