-
-If you want to request a new language support, a PR with 1 following files are needed：
-
-1. In folder [ppocr/utils/dict](./ppocr/utils/dict),
-it is necessary to submit the dict text to this path and name it with `{language}_dict.txt` that contains a list of all characters. Please see the format example from other files in that folder.
-
-If your language has unique elements, please tell me in advance within any way, such as useful links, wikipedia and so on.

+## 🇺🇳 Guideline for New Language Requests
+
+If you want to request a new language support, a PR with 1 following files are needed：
+
+1. In folder [ppocr/utils/dict](./ppocr/utils/dict),
+it is necessary to submit the dict text to this path and name it with `{language}_dict.txt` that contains a list of all characters. Please see the format example from other files in that folder.
+
+If your language has unique elements, please tell me in advance within any way, such as useful links, wikipedia and so on.
+
+More details, please refer to [Multilingual OCR Development Plan](https://github.com/PaddlePaddle/PaddleOCR/issues/1048).
