+### Bulk Tag Insertion (Pseudo "Chants")
+
+By enclosing multiple tags with `""` (double quotation marks), you can insert frequently used tags in bulk.
+This is similar to the **Chants** feature in [DominikDoom/a1111-sd-webui-tagcomplete](https://github.com/DominikDoom/a1111-sd-webui-tagcomplete?tab=readme-ov-file#chants).
+
+For example, by preparing the following CSV, you can quickly insert corresponding tags by typing `<c:Basic-HighQuality>` or `<c:Basic-Negative>`.
+
+**`danbooru_tags_chants.csv`:**
+```
+"masterpiece, best quality, high quality, highres, ultra-detailed",5,9999999,<c:Basic-HighQuality>
+"(worst quality, low quality:1.4), normal quality",5,9999999,<c:Basic-Negative>
+```
+
+>[!TIP]
+> * Text enclosed in `""` does not escape `()` (parentheses). Tags that originally contain parentheses should be written in the CSV with escaped parentheses. Example: `copyright_(series)` -> `copyright_\(series\)`
+> * The alias column also supports `""`, allowing you to assign multiple aliases

+### 複数タグの一括挿入機能（疑似 Chants）
+
+`""` （ダブルクォーテーション）で複数タグを囲むことで、よく使うタグを一括で挿入できます。
+これは [DominikDoom/a1111-sd-webui-tagcomplete](https://github.com/DominikDoom/a1111-sd-webui-tagcomplete?tab=readme-ov-file#chants) で **Chants** と呼ばれる機能に似ています。

+例として以下のCSVを用意することで、`<c:Basic-HighQuality>` や `<c:Basic-Negative>` と入力して対応したタグを素早く挿入出来ます。
+
+**`danbooru_tags_chants.csv`:**
+```
