+# openEuler Kernel Packaging Repository
+
+This repository contains RPM packaging specifications for building Linux
+kernel packages for the openEuler distribution, including spec files,
+patches, and build configurations.
+
+## Source Code Management
+
+- **Source repository**: [openeuler/kernel](https://gitee.com/openeuler/kernel)
+- **Source tags**: Specified in the `SOURCE` file within this repository
+
+## Branch Policy
+
+### master Branch
+- Tracking upstream kernel periodically (kernel.org)
+- Minimal local modifications (primarily packaging changes)
+- For build and experimentation only - no production use, no general support
+
+### LTS Branches
+- Used for openEuler LTS releases
+- Each branch is based on a specific major upstream kernel version
+- Includes:
+  - Critical security fixes (backported)
+  - Hardware enablement patches
+  - Selected stable tree patches
+  - openEuler-specific enhancements
+
+### Innovation Branches
+- Used for openEuler Innovation releases
+- Experimental branches for community innovation
+- Purpose:
+  - Feature development and prototyping
+  - Cutting-edge technology evaluation
+- Characteristics:
+  - Based on upstream versions or newer openEuler LTS kernels
+  - Used for testing and validation only - NOT for production
