 I have run **[Geekbench 4](https://browser.geekbench.com/v4/cpu/8656840)** and now I can get a score of 5391/17265! On balance_performance I can reach only 4672/16129, so **15% improvement** in single core and 7% in multicore, not bad ;)
 
 ## Requirements
-The python module `python-periphery` is used for accessing the MCHBAR register by memory mapped I/O. You also need `dbus` and `gobject` python bindings for listening to dbus signals on resume from sleep/hibernate.
+A stripped down version of the python module `python-periphery` is now built-in and it is used for accessing the MCHBAR register by memory mapped I/O. You also need `dbus` and `gobject` python bindings for listening to dbus signals on resume from sleep/hibernate.
 
 ### Secure Boot
 Right now it is mandatory to **disable Secure Boot** (in BIOS) in order to avoid [Kernel Lockdown](https://lwn.net/Articles/706637/). In particular Lockdown restricts access to MSR and PCI BAR (via /dev/mem) which are required by this script.
