 ## Build Instructions and Environment Setup
 
 ### Prerequisites
 - **JDK 17**: Required (as specified in GitHub Actions workflows)
 - **Network Access**: Required for initial builds to download Android Gradle Plugin and other dependencies
 - **Gradle 9.1.0**: Automatically handled by wrapper
 
-**IMPORTANT**: Initial builds require internet access for dependency resolution. The project cannot build in fully offline environments.

 **IMPORTANT**: If the project uses snapshot dependencies of other `com.huanshankeji` libraries, especially in a branch other than `main` such as `dev`, refer to the setup instructions at <https://github.com/huanshankeji/.github/blob/main/dev-instructions.md#about-snapshot-dependencies-of-our-library-projects>.
