+## Cool, whatever
+
+Yeah, that's fair.
+In case you still want some of the functionality, without the nice GUI, here's some equivalent commands.
+These should all be run as superuser, i.e. run `sudo su` and then run these commands in that.
+
+### Enable & Disable CPU threads
+
+Enable: `echo 1 > /sys/devices/system/cpu/cpu{cpu_number}/online` where `{cpu_number}` is a number from 1 to 7 (inclusive).
+
+Disable: `echo 0 > /sys/devices/system/cpu/cpu{cpu_number}/online` where `{cpu_number}` is a number from 1 to 7 (inclusive).
+
+NOTE: You cannot enable or disable cpu0, hence why there are only 7 in the range for 8 cpu threads.
+
+### Enable & Disable CPU boost
+
+Enable: `echo 1 > /sys/devices/system/cpu/cpufreq/boost` enables boost across all threads.
+
+Disable: `echo 1 > /sys/devices/system/cpu/cpufreq/boost` disables boost across all threads.
+
+### Set CPU frequency
+
+Use `cpupower` (usage: `cpupower --help`).
+This isn't strictly how PowerTools does it, but it's a multi-step process which can involve changing the CPU governor.
+All that can be done automatically by `cpupower frequency-set --freq {frequency}` where `{frequency}` is `1.7G`, `2.4G` or `2.8G`.
