+# Real-World Research Scenarios
+
+### 🔬 Scenario 1: Publishing alongside a paper
+````bash
+# Make repository public before paper submission
+# Tag the version used in the paper
+git tag -a v1.0-paper -m "Code for Smith et al. 2025"
+git push origin v1.0-paper
+
+# Add DOI from Zenodo for citability
+````
+
+### 🤝 Scenario 2: Multi-lab collaboration
+````bash
+# Add collaborator's fork as remote
+git remote add collaborator https://github.com/CollabLab/CellClusterFlow.git
+
+# Fetch their branches
+git fetch collaborator
+
+# Review their work
+git checkout collaborator/new-algorithm
+````
+
+### 📚 Scenario 3: Archiving for reproducibility
+- Link GitHub repo in paper's Data Availability section
+- Use Zenodo integration for permanent DOI
+- Include `environment.yml` or `requirements.txt` for exact dependencies
