 Hacky solution to integrate AMDGPU power/clock control into `tuned` profiles
 with Ansible.
 
-Provides three variations of the `tuned` profiles found in `/usr/lib/tuned`
+Extends every `tuned` profile found in `/usr/lib/tuned`
 using the [AMDGPU hwmon interfaces](https://docs.kernel.org/gpu/amdgpu/thermal.html):
 
-- `default`: the out-of-the-box configuration
-- `overclock`: the optimized card configuration. Includes all of the clock/voltage/power settings
-- `peak`: the same as `overclock`, but with clock gating removed. May help profiling
+- `default`: the out-of-the-box GPU clock/power configuration
+- `overclock`: the _optimized_ card configuration. Includes the clock/voltage/power settings outlined below.
+- `peak`: the same as `overclock`, but with clock gating removed. May help profiling.
 
-Contrary to the name, `overclock` can be used to de-tune the card as well.
