-# SSD
+# SSD - Specs for Storage Devices
+### SSD is a simple and lightweight tool to obtain some information about the storage devices found inside of your computer
+
+# How it works
+SSD parses the output of [smartctl.exe](https://www.smartmontools.org/wiki/Download), gathering the required data to supply the infromation of the drives to the program.
+- First it determines the storage devices in your computer using the `smartctl.exe --scan` command
+- Then it runs the command `smartctl.exe -x /dev/{num_of_storage_device}` for each drive found in your system
+- After that it parses the output of the commands using regular expressions
+- If the S.M.A.R.T. data does not provide the condition of the device (which it usually never does for HDD-s) it uses an algorithm based on some factors to calculate it
+
+# Compatibility
+SSD is made in .NET 4.0 so it should theoradically run on systems as low as Windows XP SP3 but its functionality is yet to be tested on older systems
+
+# How to build
+- Download the project as a .ZIP from this GitHub page
+- Open the .sln is Visual Studio
+- Click 'Build' --> 'Build Solution'
+- When it is done building make sure to place [smartctl.exe](https://sourceforge.net/projects/smartmontools/files/smartmontools/7.4/smartmontools-7.4-1.win32-x86-pre-vista-setup.exe/download) in the same directory as `SSD.exe` (It is already included in the release version, you only need to do it if you build it yourself)
+
+# Features
+SSD lists the following informations about your drives:
+- Model
+- Health
+- Temperature
+- Power-On Hours
+- Start / Stop Count (In case of HDD)
+- HWID
+- Health
+- GigaBytes Written (In case of SSD)
+- Bas Sectors (In case of HDD)
+
+# Why SSD?
+While this program might not be as advanced as other storage device info tools like `CrystalDisk Info` or `HD Sentinel` it is still a good choice if you desperately need something to check the status of your drives
