+# 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
+```

+## はじめに
+
+Gopeed (正式名 Go Speed) は `Golang` + `Flutter` によって開発された高速ダウンローダーで、(HTTP、BitTorrent、Magnet) プロトコルをサポートし、すべてのプラットフォームをサポートします。基本的なダウンロード機能に加え、[APIs](https://docs.gopeed.com/dev-api.html)との連動や[拡張機能](https://docs.gopeed.com/dev-extension.html)のインストール・開発による追加機能にも対応した、カスタマイズ性の高いダウンローダーです。

+
+## 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/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:

+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

+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
