+### Setting the number of threads
+
+When using asynchronous functions, by default, the number of threads used by these functions
+is determined by the number of physical CPUs available.
+In order to change this behaviour, set the `JAVA_BRIDGE_THREAD_POOL_SIZE` environment variable
+to the desired amount of threads.
+
+Note: Setting this to a non-numeric value will cause an error to be thrown during startup.
