-- [MongoDB Community Server](https://www.mongodb.com/try/download/community) を用意する
-- ゲームバージョンがREL4.0.Xのものを用意する (4.0.Xのクライアントを持っていない場合は右のリンクからダウンロード): https://github.com/MAnggiarMustofa/GI-Download-Library/blob/main/GenshinImpact/Client/4.0.0.md
-- [最新の Cultivation](https://github.com/Grasscutters/Cultivation/releases/latest)をダウンロードする。`.msi`インストーラを使ってください。
-- 管理者権限を付与して Cultivation を実行した後、右上端にあるダウンロードアイコンのボタンを押す。 
-- `Download All-in-One` をクリックする
-- 右上端にある歯車アイコンのボタンをクリックする。
-- `Game Install Path` にゲームファイルのパスを指定する。
-- `Custom Java Path` に、自分が用意したJavaのパスを指定する。 (例: `C:\Program Files\Java\jdk-17\bin\java.exe`)
-- その他の設定には手を付けず次の段階に進む。
 
-- Launch の隣にある小さいボタンを押す。
+  **＊:** サーバーを動作させるだけならjreのみで十分です｡ 開発をしたい場合JDKが必要になるかもしれません。
-- Launchボタンを押す
-- 好きなユーザ名でログインする。パスワードは特段気にすることはない。
 
+* [MongoDB](https://www.mongodb.com/try/download/community) (バージョン4.0以降を推奨)
+
+* プロキシツール: [mitmproxy](https://mitmproxy.org/) (mitmdump, 推奨)、[Fiddler Classic](https://telerik-fiddler.s3.amazonaws.com/fiddler/FiddlerSetup.exe)、その他｡
+
+### 起動方法
+
+**＊:** もしサーバーをアップデートしたい場合は`config.json`を削除してから再生成してください。
+
+1. `grasscutter.jar`を入手する
+   - [releases](https://github.com/Grasscutters/Grasscutter/releases/latest) か [action](https://github.com/Grasscutters/Grasscutter/actions) からダウンロードするか、[自分でビルド](#ビルド)してください｡
+2. `grasscutter.jar` があるディレクトリに `resources` フォルダーを作成し、そこに `BinOutput, ExcelBinOutput, Readables, Scripts, Subtitle, TextMap` を移動してください *(`resources` フォルダの中身の入手方法については [wiki](https://github.com/Grasscutters/Grasscutter/wiki) を参照してください.)*
+3. コマンドプロンプトに`java -jar grasscutter.jar`を入力しGrasscutterを起動してください。**このときMongoDBも実行する必要があります。**
+
+### クライアントとの接続
+
+½. [このコマンド](https://github.com/Grasscutters/Grasscutter/wiki/Commands#commands-for-server-admins)をサーバーコンソールから使用してアカウントを作成してください｡
+
+1. 通信内容をリダイレクトする: (どちらか一つを選択してください)
+    - mitmdump: `mitmdump -s proxy.py -k`
+
+      - CA証明書を信頼する:
+
+        - **＊:** CA証明書は`%USERPROFILE%\.mitmproxy`に保存されています。ダブルクリックして[インストール](https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate#installing-a-trusted-root-certificate)するか...
+
+        - コマンドライン経由でインストールします
+
+        ```shell
+        certutil -addstore root %USERPROFILE%\.mitmproxy\mitmproxy-ca-cert.cer
+        ```
+
+    - Fiddler Classic: Fiddler Classicを起動し(Tools -> Options -> HTTPS)から`Decrypt https traffic`をオンにしてください｡ (Tools -> Options -> Connections) に有るポート番号の設定を`8888`以外に設定してください。その後この[スクリプト](https://github.com/Grasscutters/Grasscutter/wiki/Resources#fiddler-classic-jscript)をFiddlerScriptタブにコピペしてロードします。
+
+    - [ホストファイル](https://github.com/Grasscutters/Grasscutter/wiki/Resources#hosts-file)
+
+2. ネットワークプロキシを `127.0.0.1:(自分で設定したポート番号)` に設定してください｡
+- mitmproxyを使用した場合：プロキシの設定と証明書のインストールが終わった後、http://mitm.it/ でトラフィックがmitmproxyを通過しているか確認しましょう。
+
+**`start.cmd`でmitmdumpとサーバーをまとめて起動することが出来ます。ただ、事前に`start_config.cmd`でJAVAのパスを指定している必要があります。**
