-> 📌 템플릿은 [HyG](https://github.com/gaohaoyang)님이 만드신 [Github 블로그 템플릿](https://github.com/Gaohaoyang/gaohaoyang.github.io)을 이용하고 있습니다.
+> 📌 The template is based on the [Github Blog Template](https://github.com/Gaohaoyang/gaohaoyang.github.io) created by [HyG](https://github.com/gaohaoyang).
 
-> 한국 버전 템플릿은 [Gid](https://github.com/goodGid)님이 만드신 [Github 블로그 템플릿](https://github.com/goodGid/goodGid.github.io)을 참고하였습니다. 
+For the Korean version of the template, I referred to the [Github Blog Template](https://github.com/goodGid/goodGid.github.io) by [Gid](https://github.com/goodGid).
+
+### Writing Commit Messages
+
+* When **creating a new post** for the first time, write the commit message as `Write {Category} Post " {Title} "`.
+
+  * Example: If the category is `DevHistory` and the title is "2024 Dev History",
+
+  * the commit message should be written as `Write DevHistory Post " 2024 Dev History "`.
+
+* If you are **updating an existing post**, write the commit message as `Update {Category} Post " {Title}`.
+
+### How to Add or Modify Categories
+
+> Unlike the original template, which generates category order randomly, I have opted for a manual addition/modification approach.
+
+* Add the desired categories to the `categories_order` section in the `_config.yml` file.
+
+* As of (2024.12.22), the **current setup** is as follows:
+
+```yaml
+categories_order:
+  - "DevHistory"
+  - "Retrospective"
+  - "TechInsight"
+  - "Java"
+  - "Spring"
+  - "SpringBoot"
+  - "JPA"
+  - "MySQL"
+  - "Flyway"
+  - "Technology"
+  # More categories...
+```
