-### 下载
+## Development
 
-前往[releases](https://github.com/monkeyWie/gopeed-core/releases)页面
+This project is divided into two parts, the front end uses `flutter`, the back end uses `Golang`, and the two sides communicate through the `http` protocol. On the unix system, `unix socket` is used, and on the windows system, `tcp` protocol is used.
 
-## TODO
+> The front code is located in the `ui/flutter` directory.

+### Clone
+
+```bash
+git clone [email protected]:monkeyWie/gopeed.git
+```
+
+### Build
+
+#### Desktop
+
+First, you need to configure the environment according to the [flutter desktop official website document](https://docs.flutter.dev/development/platform-integration/desktop), and then you need to prepare the `cgo` environment, which can be searched for yourself.
+
+command:
+
+- windows
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/windows/libgopeed.dll github.com/monkeyWie/gopeed/bind/desktop
+cd ui/flutter
+flutter build windows
+```
+
+- macos
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/macos/Frameworks/libgopeed.dylib github.com/monkeyWie/gopeed/bind/desktop
+cd ui/flutter
+flutter build macos
+```
+
+- linux
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/linux/bundle/lib/libgopeed.so github.com/monkeyWie/gopeed/bind/desktop
+cd ui/flutter
+flutter build linux
+```
+
+#### Mobile
+
+Same as before, you also need to prepare the `cgo` environment, and then install `gomobile`:
+
+```bash
+go install golang.org/x/mobile/cmd/gomobile@latest
+gomobile init
+```
+
+command:
+
+- android
+
+```bash
+gomobile bind -tags nosqlite -ldflags="-w -s" -o ui/flutter/android/app/libs/libgopeed.aar -target=android -androidapi 19 -javapkg=com.gopeed github.com/monkeyWie/gopeed/bind/mobile
+cd ui/flutter
+flutter build apk
+```
+
+#### Web
+
+Web platform communicates directly with the backend http server, no additional environment is required.
+
+command:
+
+```bash
+cd ui/flutter
+flutter build web
+cd ../../
+cp -r ui/flutter/build/web cmd/web/dist
+go build -tags nosqlite,web -ldflags="-s -w" -o bin/ github.com/monkeyWie/gopeed/cmd/web
+````

+## 介绍
+
+Gopeed 是一款由`Golang`+`Flutter`开发的高速下载器，支持（HTTP、BitTorrent、Magnet）协议下载，并且支持全平台使用。
+
+## 下载
+
+**已支持平台**
+
+- [x] windows
+- [x] macos
+- [x] linux
+- [x] android
+- [ ] ios
+- [x] web
+- [x] docker
+
+[点击前往](https://github.com/monkeyWie/gopeed/releases/latest)
+
+> 注：macos 版本运行如果提示损坏，请在终端执行 `xattr -d com.apple.quarantine /Applications/Gopeed.app` 命令
+
+### 命令行工具
+
+使用`go install`安装：
+
+```bash
+go install github.com/monkeyWie/gopeed/cmd/gopeed
+```
+
+### Docker
+
+```bash
+docker run -d -p 9999:9999 -v /path/to/download:/download liwei2633/gopeed
+```
+
+当 docker 容器运行时，可以通过 `http://localhost:9999` 访问 web 页面。
+> 提示：在设置页面把下载路径修改为 `/download` 以便在宿主机访问下载完的文件。
+
+## 界面展示
+
+![](_docs/img/ui-demo.png)
+
+## 开发
+
+本项目分为前端和后端两个部分，前端使用`flutter`，后端使用`Golang`，两边通过`http`协议进行通讯，在 unix 系统下，使用的是`unix socket`，在 windows 系统下，使用的是`tcp`协议。
+
+> 前端代码位于`ui/flutter`目录下。
+
+### 环境要求
+
+1. Golang 1.19+
+2. Flutter 3.0+
+
+### 克隆项目
+
+```bash
+git clone [email protected]:monkeyWie/gopeed.git
+```
+
+### 编译
+
+#### 桌面端
+
+首先需要按照[flutter desktop 官网文档](https://docs.flutter.dev/development/platform-integration/desktop)进行环境配置，然后需要准备好`cgo`环境，具体可以自行搜索。
+
+构建命令：
+
+- windows
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/windows/libgopeed.dll github.com/monkeyWie/gopeed/bind/desktop
+cd ui/flutter
+flutter build windows
+```
+
+- macos
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/macos/Frameworks/libgopeed.dylib github.com/monkeyWie/gopeed/bind/desktop
+cd ui/flutter
+flutter build macos
+```
+
+- linux
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/linux/bundle/lib/libgopeed.so github.com/monkeyWie/gopeed/bind/desktop
+cd ui/flutter
+flutter build linux
+```
+
+#### 移动端
+
+同样的也是需要准备好`cgo`环境，接着安装`gomobile`：
+
+```bash
+go install golang.org/x/mobile/cmd/gomobile@latest
+gomobile init
+```
+
+构建命令：
+
+- android
+
+```bash
+gomobile bind -tags nosqlite -ldflags="-w -s" -o ui/flutter/android/app/libs/libgopeed.aar -target=android -androidapi 19 -javapkg=com.gopeed github.com/monkeyWie/gopeed/bind/mobile
+cd ui/flutter
+flutter build apk
+```
+
+#### Web 端（推荐本地调试使用）
+
+Web 端直接与后端 http 服务通讯，不需要额外准备环境。
+
+构建命令：
+
+```bash
+cd ui/flutter
+flutter build web
+cd ../../
+cp -r ui/flutter/build/web cmd/web/dist
+go build -tags nosqlite,web -ldflags="-s -w" -o bin/ github.com/monkeyWie/gopeed/cmd/web
+```

+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.
