+### Quick CLI Usage
+
+After installation, you can use the CLI in two ways:
+
+**Option 1: Direct command (if PATH is configured)**
+```bash
+qrs --help
+# generate synthetic sample price series
+qrs generate-data -o data_sample/sample_prices.csv -s 5 -d 365
+# compute example factors
+qrs compute-factors -d data_sample/sample_prices.csv -f momentum -f value -o output/factors.csv
+# run a backtest
+qrs backtest -d data_sample/sample_prices.csv -s output/factors.csv -o output/backtest_results.json
+```
+
+**Option 2: Python module (always works)**
+```bash
+python -m quant_research_starter.cli --help
+python -m quant_research_starter.cli generate-data -o data_sample/sample_prices.csv -s 5 -d 365
+python -m quant_research_starter.cli compute-factors -d data_sample/sample_prices.csv -f momentum -f value
+python -m quant_research_starter.cli backtest -d data_sample/sample_prices.csv -s output/factors.csv -o output/backtest_results.json
+```
