 That's it. The `Supervisor` will take care that even if your jobs are still running after a minute has passed, only 
 ever your maximum number of processes will be created.
 
-For this to work, it uses `ps -p <pid>` to check for the process details. Windows is currently not supported.
+For this to work, it uses multiple providers to check if processes are still running. Currently supported are:
+
+* `posix_getpgid()`
+* `ps -p <pid>`
+* `tasklist /FI PID eq <pid>`

+Which means you should be able to run it on most Linux and Windows combinations.
