+
+配布された`server.properties`を使う場合は、サーバーを停止して「サーバー設定 → server.propertiesをインポート」を選ぶか、`mcserver-kit server <server-id> import-properties /path/to/server.properties`を実行します。Windowsダイアログを有効にしているWSL環境では、設定画面からWindowsのファイル選択画面を開けます。既存のデータファイルは置換前にバックアップします。対応する項目を`server.env`へ取り込み、その他のキーは`CUSTOM_SERVER_PROPERTIES`へ保存します。設定の正本は引き続き`server.env`で、元ファイルも`data/server.properties`へコピーします。ワールド名やポートがこのサーバー構成と異なる場合、または未対応の書式の場合は黙って変更せずエラーにします。サーバー起動中にファイルを直接編集しないでください。

 The editor covers MOTD, difficulty, game mode, player limit, online mode, whitelist, operators, flight, command blocks, PvP, view and simulation distance, spawn protection, Nether and entity spawning, and resource packs.
 
-`server.env` is the source of truth for settings managed by the toolkit. Docker Compose passes these values to `itzg/minecraft-server`, which applies them to `server.properties` when the container starts.
+Normally, `server.env` is the source of truth for settings managed by the toolkit. Docker Compose passes these values to `itzg/minecraft-server`, which applies them to `server.properties` when the container starts.
+
+For a distributed `server.properties`, stop the server and choose **Server settings → Import server.properties**, or run `mcserver-kit server <server-id> import-properties /path/to/server.properties`. On WSL, the settings screen offers a Windows file picker when Windows dialogs are enabled. The existing data file is backed up before replacement. Supported properties are imported into `server.env`; additional keys are stored in `CUSTOM_SERVER_PROPERTIES`. `server.env` remains the source of truth, and the imported file is also copied to `data/server.properties`. Imports with a nonstandard world name, port, or unsupported property syntax are rejected rather than silently changing the server layout. Do not edit the file while the server is running.
+
+The dashboard can also open the server folder or its persistent `data/` folder in Windows Explorer. From a terminal, use `mcserver-kit server <server-id> open server` or `open data`. This requires WSL interop with Explorer.
 
 When an older server is opened for the first time, the editor asks before migrating it. The original Compose file is saved as `compose.yaml.mcserver-kit.bak`.
