+# 1. Introduction
+
+luasystem is a platform independent system call library for Lua.
+Supports Unix, Windows, MacOS, `Lua >= 5.1` and `luajit >= 2.0.0`.
+
+Lua is typically platform independent, but it requires adhering to very old C
+standards. This in turn means that many common features (according to todays standards)
+are not available. This module attempts to overcome some of those hurdles by providing
+functions that cover those common needs.
+
+This is not a kitchen sink library, but a minimalistic one with a focus on platform
+independence.
