-## About
+## 📖About
 
-## Disclaimer
+Drive Health is a program written in golang to help with tracking and monitoring of your hardware's temperature.
 
-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.
+This tool has been created by [me](https://danlegt.com) with the purpose of installing it in different servers I own with different configurations to help keep track of the temperature of different hard-disks, ssds, nvme drives, etc... The testing has been very limited to only 4 different computers and not on laptops so expect some mishaps.
 
-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.
+## ❗Disclaimer
 
-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 :)
+I'm not exactly a linux hardware wizard, so I honestly have no clue about a lot of things and I myself can tell there's a lot to improve upon and that there's a lot of other things missing that are a little bit more obscure, I personally don't currently own any m.2 sata drives to test the code on, or many of the other drive types, I have only tested on HDD, SSD and NVMe drives, any issues opened would help me so much!
 
-## How to use
+## Requirements
+1. A linux machine, this will NOT work on macOS or on Windows, it's meant to be ran on servers as a service with which administrators can privately connect to for temperature logging.
+
+2. Please make sure you have the [**drivetemp kernel drive**](https://docs.kernel.org/hwmon/drivetemp.html) you can check this by running `sudo modprobe drivetemp`.
+The program depends on this to be able to log the temperature of your devices.
+
+
+## 📖How to use
+
+The program is straight forward to use really, edit the [.env](./.env) file and make the changes you would like applied.
+
+### Docker ( Recommended/Hassle free )
+
+### SystemD
+```toml
+[Unit]
+Description=Drive Health Service
+After=network.target
+
+[Service]
+Type=simple
+User=daniel # Your user here
+WorkingDirectory=/home/daniel/services/drive-health # The path to the service's directory
+ExecStart=/home/daniel/services/drive-health/drive-health # The path to the binary
+Restart=on-failure
+
+[Install]
+WantedBy=multi-user.target
+```
+
+## ❔FAQ
+
+### How does it work?
+Currently the program does not depend on any hardware library as I couldn't find anything that would not require root access while giving me the possibility to interrogate the temperature of the drives, I chose not to depend on `lsblk` either, so how does the program work? Well it looks in `/sys/block` and simply
+
+### Why not just run as root?
+I really, really, **really** want to avoid asking people to run **ANY** program I write as root and even try and prevent that from happening since that's how things can go bad, especially because I am runnig actions over hardware items. I think you can see how easy it is for a mistake or a **malicious attack** to easily deal damage
