+# Gopeed 協助指南
+
+首先感謝您願意幫助我們改進並優化該項目，這份指南將會幫助您更好的參與 Gopeed 的開發。
+
+## 分支說明
+
+本項目只有一個分支，即 `main` 分支，如果您想要參與 Gopeed 的開發，請先 fork 該項目，再在您自己的 fork 中進行開發，開發完成後再開啟PR，以合併至 `main` 分支。
+
+## 離線開發
+
+建議使用 web 端進行開發與調試，首先啟動服務，使用指令 `go run cmd/api/main.go` 啟動 ，該服務默認連接埠為 `9999`，接著以 `debug` 模式啟動前端 flutter 項目即可。
+
+## 翻譯
+ 
+Gopeed 的翻譯文件位於 `ui/flutter/lib/i18n/langs` 目錄中，只需要修改或新建翻譯文件即可。
+
+
+請以 `en_us.dart` 作為參照。
+
+## flutter開發
+
+每次提交PR前請務必執行 `dart format ./ui/flutter`
+
+如果需要編輯 api/models，請打開build_runner watcher:
+
+```
+flutter pub run build_runner watch
+```

+
+## 軟體介面
+
+![](_docs/img/ui-demo.png)
+
+## 開發
+
+該項目分為前端與後端，前端使用`flutter`編寫，後端使用`Golang`編寫，兩邊通過`http`協定進行通訊，在 unix 系統下，則使用`unix socket`，在 windows 系統下，則使用`tcp`協定。
+
+> 前端代碼位於`ui/flutter`目錄內。
+
+### 開發環境
+
+1. Golang 1.19+
+2. Flutter 3.10+
+
+### 克隆項目
+
+```bash
+git clone [email protected]:GopeedLab/gopeed.git
+```
+
+### 協助開發
+
+請參考[協助指南](CONTRIBUTING_zh-TW.md)
+
+### 編譯
+
+#### 桌面端
+
+首先需要按照[flutter desktop 官方文檔](https://docs.flutter.dev/development/platform-integration/desktop)配置開發環境，並準備好`cgo`環境，具體方法可以自行搜索。
+
+組建指令：
+
+- windows
+
+```bash
+go build -tags nosqlite -ldflags="-w -s" -buildmode=c-shared -o ui/flutter/windows/libgopeed.dll github.com/GopeedLab/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/GopeedLab/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/GopeedLab/gopeed/bind/desktop
+cd ui/flutter
+flutter build linux
+```
+
+#### 移動設備
+
+需要`cgo`環境，並安裝`gomobile`：
+
+```bash
+go install golang.org/x/mobile/cmd/gomobile@latest
+go get golang.org/x/mobile/bind
+gomobile init
+```
+
+組建指令：
+
+- 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/GopeedLab/gopeed/bind/mobile
+cd ui/flutter
+flutter build apk
+```
+
+- ios
+
+```bash
+gomobile bind -tags nosqlite -ldflags="-w -s" -o ui/flutter/ios/Frameworks/Libgopeed.xcframework -target=ios github.com/GopeedLab/gopeed/bind/mobile
+cd ui/flutter
+flutter build ios --no-codesign
+```
+
+#### 網頁端
+
+組建指令：
+
+```bash
+cd ui/flutter
+flutter build web
+cd ../../
+rm -rf cmd/web/dist
+cp -r ui/flutter/build/web cmd/web/dist
+go build -tags nosqlite,web -ldflags="-s -w" -o bin/ github.com/GopeedLab/gopeed/cmd/web
