## About
+## Disclaimer
-## How to use
\ No newline at end of file
+This software is only meant to run on linux, it's something I threw together all at once in one sitting without really thinking about structure or even caring about anything but making it work.
+
+It's actually meant to run on my own server just so I can track the temperature of my harddrives in a live environment, I just want this service to run, record the status of the harddrives, and be able via my VPN to access it in a private manner, it's not meant to be dockerized, it's not meant to be ran in a VM, it's meant to be ran either as a `service` or in a [screen](https://git.savannah.gnu.org/cgit/screen.git) in the background.
+
+It's not really meant to run all the time or anything like that, I just wanted to write this disclaimer, feel free to use the code any way you want to :)
