+## Development
+- For the **development** purpose, this project uses the `dev` branch to deploy and build the image. Followings are the steps to build and push new images to VngCloud Registry:
+  ```bash
+  # Make sure you are on the `dev` branch
+  git add .
+  git commit -am "[build] This is a really spectacular feature for this plugin"
+  git push
+  ```
+
+## Production
+- The branch `main` is used to trigger the release workflow via GitHub actions. To deploy your new code as the latest stable version, follow these steps:
+  ```bash
+  # Make sure you are on the `main` branch
+  git add .
+  git commit -am "[release] This is a really spectacular feature for this plugin"
+  git tag -am "[release] This is a really spectacular feature for this plugin" v1.0.0
+  git push --tags
+  ``` 
+  - The above steps also trigger to create a new **Release** in GitHub.
