+# Introduction
+
+Ion is a modern system shell that features a simple, yet powerful, syntax. It is written entirely
+in Rust, which greatly increases the overall quality and security of the shell, eliminating the
+possibilities of a [ShellShock](http://www.wikiwand.com/en/Shellshock_(software_bug))-like vulnerability
+, and making development easier. It also offers a level of performance that exceeds that of Dash,
+when taking advantage of Ion's features. While it is developed alongside, and primarily for, RedoxOS,
+it is a fully capable on other \*nix platforms.
