+# SonarQube Analysis
+
+This directory contains the configuration and scripts for running automated SonarQube analysis on cuOpt branches.
+
+## Files
+
+- `sonar-branches.txt` - List of branches to analyze (one per line)
+- `run-sonar-analysis.sh` - Automated script that clones, builds, and analyzes branches
+
+## Quick Start
+
+### 1. Configure Branches
+
+Edit `sonar-branches.txt` to specify which branches to analyze:
+
+```bash
+# One branch per line
+main
+release/26.02
+
+# Lines starting with # are comments
+# Empty lines are ignored
+```
+
+### 2. Set Required Environment Variable
+
+The script requires authentication:
+
+```bash
+export SONAR_TOKEN="your_token_here"
+```
+
+**Note**: Contact the cuOpt team for token details.
+
+### 3. Run the Analysis
+
+```bash
+cd /path/to/cuopt
+./sonarqube/run-sonar-analysis.sh
+```
+
+## Script Behavior
+
+The script will automatically:
+
+1. ✅ Validate branch configuration file exists and has at least one branch
+2. ✅ Clone each branch into a fresh temporary directory
+3. ✅ Create an isolated conda environment per branch
+4. ✅ Build the project using `./build.sh`
+5. ✅ Run SonarQube analysis with branch-specific tagging
+6. ✅ Clean up temporary files and conda environments
+7. ✅ Provide a summary of successful and failed branches
+
+## Support
+
+**Contact**: cuOpt team
+
+For issues with:
+- Build failures: See [CONTRIBUTING.md](../CONTRIBUTING.md)
+- Script bugs: Report to the cuOpt team
