+### Thread-based parallelism
+
+The script now supports hybrid process/thread parallelism to optimize resource usage when monitoring many servers:
+
+```bash
+python ipmi_pub.py -U <username> -P <password> -f <bmc_ip_file> -T 10 run
+```
+
+This will create process groups, each running up to 10 threads to monitor servers. This approach is more resource-efficient than the default process-only model when dealing with large numbers of servers.
+
 ## Systemd
 
 This script is intended to be used as a service under systemd. SIGINT should be used as the signal to cleanly stop/kill the running script.
