+## AutoASPM
+
+Simple script to enable [Active State Power Management](https://en.wikipedia.org/wiki/Active_State_Power_Management) on all of your PCIe devices
+
+This script supports only Linux systems
+
+This is a Nushell port of [auto-ASPM.py](https://github.com/notthebee/AutoASPM) written mostly as an exercise in binary operations in Nushell.
+There are several undocumented magic constants in the code that hail back from the original [enable_aspm](https://www.uwsg.indiana.edu/hypermail/linux/kernel/1006.2/02177.html) script
+
+### Usage
+
+1. Ensure you have following binaries available on `PATH`: `lspci` `setpci`, those come as part of `pciutils` package on most distros
+2. Run the script as root (Necessary because regular users cannot access low-level device information needed for the script to work)
