+# Gopeed contributors guide
+
+Firstly, thank you for your interest in contributing to Gopeed. This guide will help you better
+participate in the development of Gopeed.
+
+## Branch description
+
+This project only has one main branch, namely the `main` branch. If you want to participate in the
+development of Gopeed, please fork this project first, and then develop in your fork project. After
+development is completed, submit a PR to this project and merge it into the `main` branch.
+
+## Local development
+
+It is recommended to develop and debug through the web. First, start the backend service, and start
+it by the command line `go run cmd/api/main.go`, the default port of the service is `9999`, and then
+start the front-end flutter project in `debug` mode to run.
+
+## Translation
+
+The internationalization files of Gopeed are located in the `ui/flutter/assets/locales` directory.
+You only need to add the corresponding language file in this directory.
+
+
+Generate locales after you edit locales:
+
+
+```
+get generate locales 
+```
+
+Please refer to `en_us.dart` for translation.
+
+## flutter development
+
+Don't forget to run`dart format ./ui/flutter`before you commit to keep your code in standard dart format
+
+Turn on build_runner watcher if you want to edit api/models:
+
+```
+flutter pub run build_runner watch
+```
+
+
+get-cli commands usages:
+
+```
+ 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 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 贡献指南
+
+首先感谢您对贡献代码感兴趣，这份指南将帮助您更好的参与到 Gopeed 的开发中来。
+
+## 分支说明
+
+本项目只有一个主分支，即 `main` 分支，如果您想要参与到 Gopeed 的开发中来，请先 fork 本项目，然后在您的 fork 项目中进行开发，开发完成后再向本项目提交
+PR，合并到 `main` 分支。
+
+## 本地开发
+
+建议通过 web 端进行开发调试，首先启动后端服务，通过命令行 `go run cmd/api/main.go` 启动 ，服务启动默认端口为 `9999`，然后以 `debug` 模式启动前端
+flutter 项目即可运行。
+
+## 翻译
+ 
+Gopeed 的国际化文件位于 `ui/flutter/assets/locales` 目录下，只需要在该目录下添加对应的语言文件即可。
+
+编辑locales后请运行以下命令:
+
+```
+get generate locales 
+```
+
+请注意以 `en_US.json` 为参照进行翻译。
+
+## flutter开发
+
+每次提交前请务必`dart format ./ui/flutter`
+
+如果要编辑api/models，请打开build_runner watcher:
+
+```
+flutter pub run build_runner watch
+```
+
+适用get-cli 命令:
+
+```
+ create:  
+    controller:  Generate controller
+    page:  Use to generate pages
+    view:  Generate view
+  generate:
+    locales:  Generate translation file from json files

+### 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
+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
+```
+
+#### 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
