+ビルド手順
+====
+
+code-serverを開いている前提
+
+## 操作手順
+
+1. code-serverでの作業
+ 1. code-serverでsolitudeのnpmプロジェクトに移動
+ 1. @npm run build-ready@を実行する
+ 1. ~/public/solitude/solitude.jsが出来ているのを確認する
+1. ビルド用端末での作業
+ 1. https://www.sylow-castle.work/solitude/solitude.js をダウンロード・回答する
+ 1. @npm run portable@を叩く
+ 1. distディレクトリの中にできあがる
+
+上記はビルド環境を「electron-builder」による構築をした場合。
+ビルド環境が手動の場合、solitude.jsの中身をapp以下に配置でOK。
+
+## ビルド環境構築
+
+### electron-builder
+
+ポータブルな感じで作る。
+
+1. Node.jsの入手：https://nodejs.org/ja/download/ から Windows Binary(.zip) 64-bit
+1. zipを回答node.exeと同じディレクトリに以下のファイル内容で「node-powershell.bat」で作成：
+```
+@echo off
+set PATH=%PATH%;%cd%
+set NODE_PATH=%cd%\node_modules\npm\node_modules;%cd%\node_modules\npm
+powershell
+```
+1. package.jsonのあるディレクトリにcdして@node install@を実行
+
+### 手動
+
+参考：
+https://www.electronjs.org/docs/latest/tutorial/application-distribution
+
+1. https://github.com/electron/electron/releases から「electron-${OS}-${Arch}.zip」をダウンロード・解凍
+1. resourceフォルダにappディレクトリを作成
