+# Description #
+System Information is a library written in Rust that returns certain information about your local system.
+It supports various Linux distros, Mac OS, and Windows.
+Currently, it can get information about the current user, the hostname, the operating system, the disk, memory, and the CPU.
+Additionally, it can present the disk and memory information in raw number of bytes or a human readable format.
+
+
+# Specifics #
+System Information uses Rust's conditional compilation feature, so it compiles different versions of functions and their helper functions depending on the operating system it's running on.
+This allowed me to compile the library with different dependencies and other libraries depending on the operating system.
+
+
+## Linux ##
+I decided to create this library because I was unhappy with what I had found with other similar libraries.
+All that I found used commands that didn't exist on my system, so I decided to try to make one avoiding commands that didn't necessarily exist.
+System Information either uses commands that are part of the coreutils package or reads from a file to get information.
+
+
+## Mac OS ##
+Mac OS is far more consistent than Linux so I felt a little more free to use commands to get information.
+Specifically, the `sysctl` command is used to get hardware information.
+
+
+## Windows ##
+Windows was far more difficult than Mac OS and Linux.
+Luckily, windows.h is an excellent Windows-specific header file for C and C++, so anything I couldn't do in Rust I was able to do by writing a C++ program that would output the desired information and then capturing that output in Rust.
