 ## Quick start
 
-### Create baseline
+Use this flow to get ndrift running on a real directory, including cron scheduling.
+
+1. Create the first baseline.
+
+~~~bash
+sudo /usr/local/bin/ndrift init /path/to/monitor --config /etc/ndrift/ndrift.conf
+~~~
+
+2. Run an immediate scan to confirm it works.
 
 ~~~bash
-/usr/local/bin/ndrift init /path/to/monitor --config /etc/ndrift/ndrift.conf
+sudo /usr/local/bin/ndrift scan --config /etc/ndrift/ndrift.conf
 ~~~
 
-### Run scan
+3. Review the latest report.
 
 ~~~bash
-/usr/local/bin/ndrift scan --config /etc/ndrift/ndrift.conf
+sudo /usr/local/bin/ndrift report --config /etc/ndrift/ndrift.conf
 ~~~
 
-### Run scan with JSON output
+4. Install a cron entry manually.
 
 ~~~bash
-/usr/local/bin/ndrift scan --json --config /etc/ndrift/ndrift.conf
+CRON_LINE="$(sudo /usr/local/bin/ndrift cron --config /etc/ndrift/ndrift.conf)"
+(sudo crontab -l 2>/dev/null; echo "$CRON_LINE") | sudo crontab -
+sudo crontab -l | grep ndrift
 ~~~
 
-### Run continuous watch mode
+5. Validate that scans are running from cron.
 
 ~~~bash
-/usr/local/bin/ndrift watch --interval 60 --config /etc/ndrift/ndrift.conf
+sudo tail -n 50 /var/log/ndrift/ndrift.log
+sudo /usr/local/bin/ndrift report --config /etc/ndrift/ndrift.conf
 ~~~
 
-### Print latest report
+6. Optional: run continuous watch mode for debugging.
 
 ~~~bash
-/usr/local/bin/ndrift report --config /etc/ndrift/ndrift.conf
+sudo /usr/local/bin/ndrift watch --interval 60 --config /etc/ndrift/ndrift.conf
 ~~~
 
+If you change cron_schedule in config, run the cron command again and replace the existing crontab entry.
