 ### Parallelizing Quark
-Now Quark supports multiprocessing for analyzing APKs parallelly, by adding the option `--multi-process` and set the number of processes. (the default is the number of CPUs in your computer.)
+Now Quark supports multiprocessing for analyzing APKs parallelly. By adding the option `--multi-process`, you can set the number of processes. 
+
+**Note:** Quark-Engine automatically limits this value to be less than or equal to the number of CPUs - 1. This restriction is done to avoid the CPU from running out of memory.
