+# Gopeed コントリビューターガイド
+
+まず最初に、Gopeed への貢献に興味を持っていただきありがとうございます。このガイドは、あなたが Gopeed の
+開発に参加するための手助けとなるでしょう。
+
+## ブランチの説明
+
+このプロジェクトのメインブランチは `main` ブランチのみです。Gopeed の開発に参加したい場合は、
+まずこのプロジェクトをフォークし、フォークしたプロジェクトで開発を行ってください。開発が完了したら、
+このプロジェクトに PR を提出し、`main` ブランチにマージしてください。
+
+## ローカル開発
+
+開発およびデバッグはウェブ上で行うことを推奨する。まずバックエンドのサービスを起動し、
+コマンドライン `go run cmd/api/main.go` で起動する。サービスのデフォルトポートは `9999` で、
+次にフロントエンドの flutter プロジェクトを `debug` モードで起動して実行します。
+
+## 翻訳
+
+Gopeed の国際化ファイルは `ui/flutter/assets/locales` ディレクトリにあります。
+このディレクトリに対応する言語ファイルを追加するだけでよいです。
+
+
+ロケール編集後にロケールを生成:
+
+
+```
+get generate locales
+```
+
+翻訳については `en_us.dart` を参照してください。
+
+## flutter での開発
+
+コミットする前に `dart format ./ui/flutter` を実行し、コードを標準の dart フォーマットにしておくことを忘れないでください
+
+api/models を編集したい場合は build_runner watcher をオンにします:
+
+```
+flutter pub run build_runner watch
+```
+
+
+get-cli コマンドの使用法:
+
+```
+ create:
+    controller:  Generate controller
+    page:  Use to generate pages
+    view:  Generate view
+  generate:
+    locales:  Generate translation file from json files
+    model:  generate Class model from json
+```

+# 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/assets/locales` 目錄中，只需要修改或新建翻譯文件即可。
+
+修改locales後請執行一下指令:
+
+```
+get generate locales 
+```
+
+請以 `en_US.json` 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
+```
+
+適用於 get-cli 的指令:
+
+```
+ create:  
+    controller:  Generate controller
+    page:  Use to generate pages
+    view:  Generate view
+  generate:
+    locales:  Generate translation file from json files
+    model:  generate Class model from json
+```
+

+## ショーケース
+
+![](_docs/img/ui-demo.png)
+
+## 開発
+
+このプロジェクトは二つの部分に分かれており、フロントエンドでは `flutter` を、バックエンドでは `Golang` を使用し、両者は `http` プロトコルで通信する。ユニックスシステムでは `unix socket` を、ウィンドウズシステムでは `tcp` プロトコルを使用します。
+
+> フロントコードは `ui/flutter` ディレクトリにあります。
+
+### 環境
+
+1. Go 言語 1.19+
+2. Flutter 3.10+
+
+### クローン
+
+```bash
+git clone [email protected]:GopeedLab/gopeed.git
+```
+
+### コントリビュート
+
+[CONTRIBUTING.md](/CONTRIBUTING_ja-JP.md) をご参照ください
+
+### ビルド
+
+#### デスクトップ
+
+まず、[flutter デスクトップ公式サイトドキュメント](https://docs.flutter.dev/development/platform-integration/desktop)に従って環境を設定し、自分で検索できる `cgo` 環境を用意します。
+
+コマンド:
+
+- 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
+```
+
+#### モバイル
+
+先ほどと同じように、`cgo` 環境を準備し、`gomobile` をインストールする必要があります:
+
+```bash
+go install golang.org/x/mobile/cmd/gomobile@latest
+go get golang.org/x/mobile/bind
+gomobile init
+```
+
+コマンド:
+
+- 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

+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
+```
+
+#### Web
+
+コマンド:
+
+```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

+## 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
+go run cmd/web/main.go
