 A library and command-line interface (CLI) converter between cut-out animation formats, including kanim (Klei animation) and scml (Spriter) with a common, intermediate in-memory format. KSE was developed to support *Oxygen Not Included* modding, and therefore features will focus on those that are useful for ONI.
 
 KSE is, at its base, a port of kparserX from Java to C#, and wouldn't have been possible without @daviscook477's work on kparser.

+## Installing
+
+KSE is a dotNET application. This means that you don't need to install the program. Just download the appropriate version [from here](https://github.com/skairunner/kanimal-SE/releases). Below is a quick guide to which version is right for you.
+
+### Which file to download
+
+There are three supported operating systems (Windows, MacOS and Linux) and two types of packaging (dotNET dependent and self-contained), meaning six downloads possible. **If you already have dotNET v3 or higher installed** on your computer, use the NET Dependent download to have a much smaller file size (631 kb vs 29MB). If you don't have dotNET installed, or don't want to risk the program not working, I recommend downloading the self-contained version instead.  
+
 ## Usage
 
 KSE is a command line tool. This means that you need a terminal to run the program, via typing in the magic incantations.
