+## Key Findings
+
+### Topic Distribution (V2 Analysis)
+- **Fiqh**: 40.4% (includes all halal/haram questions)
+- **Islamic Life & Thought**: 23.9%
+- **Quran**: 8.5%
+- **Other**: 8.0%
+- **Hadith**: 6.5%
+
+### PII Analysis
+- **97.7%** of threads have low PII risk (confidence < 0.3)
+- **93.4%** have zero PII (confidence = 0.0)
+- Only **1.0%** high risk (confidence ≥ 0.7)
+
+### Language Distribution
+- **English**: 74.3%
+- **Arabic**: 10.2%
+- **Urdu**: 5.0%
+- **Indonesian**: 2.1%
+
+## Usage
+
+### Running V2 Analysis
+```bash
+python analysis/scripts/analyze_threads_v2_parallel.py --workers 30
+```
+
+### Monitoring Progress
+```bash
+python analysis/scripts/monitor_v2_progress.py
+```
+
+### Extracting Non-PII Quran Questions
+```bash
+python analysis/scripts/extract_quran_no_pii.py
+```
+
+## Notes
+
+- All data in `/data-local` is gitignored to prevent large files from being committed
+- The v2 analysis uses Gemini 2.5 Flash for classification
+- Analysis achieved 99.99% success rate (only 2 errors out of 22,081 threads)
