+Large-scale WebGL-powered Geospatial data visualization analysis framework.
+
+[中文 README](./README.md)
+
+[GitHub](https://github.com/antvis/L7)
+
+Powered by WebGL, the rendering technology of L7 supports fast and efficient rendering of big data, 2D/3D rendering, possible through calculation and analysis of spatial data by GPU Parallel Compu-ting.
+
+L7 focuses on geographic data expressiveness，interaction and design of geographic visualization layers. The basemaps on the platform are powered by third-party services

+
+## 🌟 Highlight features of L7 2.0
+
+- 🌏 Data-driven Visualization
+
+  Layer visualization API design base Semiology of Graphics.
+
+  It supports rich map visualization types for a better insight on data.
+
+- 🌏 High performance rendering with 2D/3D effect
+  Real-time and dynamic rendering with millions of spatial data.
+
+- 🌏 Simple and flexible data format
+
+  L7 supports a wide variety of data formats including CSV, JSON, geojson, among others, eliminating the need to run conversions ahead of time.
+
+- 🌏 Multi-basemap
+
+  For global users, Mapbox is easy to be embedded by a simple line of code.
+
+## Getting Started
+
+### 📦 Installation
+
+```bash
+npm install @antv/l7
+```
+
+### Init Map by L7 scene
+
+```javascript
+import { Scene } from '@antv/l7';
+import { Mapbox } from '@antv/l7-maps';
+
+const scene = new Scene({
+  id: 'map',
+  map: new Mapbox({
+    style: 'light',
+    pitch: 0,
+    center: [107.054293, 35.246265],
+    zoom: 4.056,
+  }),
+});
+```
+
+### Add Layer
+
+```javascript
+import { PointLayer } from '@antv/l7';
+
+const pointLayer = new PointLayer()
+  .source(data)
+  .shape('circle')
+  .size('mag', [1, 25])
+  .color('mag', ['#5B8FF9', '#5CCEA1'])
+  .style({
+    opacity: 0.3,
+    strokeWidth: 1,
+  });
+
+scene.addLayer(pointLayer);
+```

+  }),
+});
 ```
 
-将 lodash 添加为所有 package 的依赖(不包含root）
-```bash
-yarn workspaces run add lodash
+### 添加图层
+
+```javascript
+import { PointLayer } from '@antv/l7';
+
+const pointLayer = new PointLayer()
+  .source(data)
+  .shape('circle')
+  .size('mag', [1, 25])
+  .color('mag', ['#5B8FF9', '#5CCEA1'])
+  .style({
+    opacity: 0.3,
+    strokeWidth: 1,
+  });
+
+scene.addLayer(pointLayer);
 ```
 
-将 typescript 设置为 root 的开发依赖
-```bash
-yarn add -W -D typescript jest
-```
