+## Guideline for Localization
+
+- ALCOM is cross-platform, so please use os-independent words as possible.
+  - For example, use "Directory" instead of "Folder"
+- It's not required to translate technical words to your language, you can use them as it is.
+  - You may use English words as it is, and you may use transliteration if it's common in your language.
+    - In Japanese, "プロジェクト" is used for "Project".
+- It's not required to translate word by word, you can use some other expressions if user can understand well.
+  - It's important for users to understand the meaning or behavior of the application.
+  - If you think another expression is better for all languages, please suggest in [Text Representation Discussion](https://github.com/vrc-get/vrc-get/discussions/894).
