+# v0.2.0
+
+change_everyを追加したのじゃ！
+
+`ComfyUI-PromptRandomChoice` は、プロンプト候補リストから実行のたびにランダムで1項目を選び、ポジティブプロンプトなどへ追加しやすい形で出力する ComfyUI カスタムノードです。
+
+## 主な機能
+
+- プロンプト候補から実行ごとにランダムで1項目を選択
+- 候補は `|` または実際の改行で区切り
+- 候補の前後にある空白や `,` を自動で trim
+- 選ばれた候補を `,coffee shop,` のように前後カンマ付きで出力
+- `change_every` に対応
+  - `1` なら毎回選び直し
+  - `3` なら同じ候補を3回返してから次を選択
+- 実行中の選択結果をノードタイトルに表示
+  - 例: `Choice: coffee shop`
+  - 例: `Choice: lake (2/3)`
+- 複数ノード設置に対応
+  - 背景用、時間帯用、天気用などを別々にランダム化可能
+- 同じ候補を複数回書くことで、選ばれやすさを調整可能
+  - 例: `day|day|day|sunset|night`
+
+## 注意
+
+区切り文字は **実際の改行** または **`|`** です。
+
+`,` は区切り文字ではありません。  
+ただし、各候補の前後に付いている `,` は自動で取り除きます。
+
+詳しい使い方は README.md を参照してください。
