>What is MUGEN?
MUGEN is a freeware proprietary 2d fighting game engine developed by Elecbyte.  The engine is written in C and uses the SDL Library, and stages, characters, screenpacks, life bars, and even engine modifications have been made by the community.  Although full games have been made in MUGEN, the engine has been widely used to make one's dream fighting game roster and make cartoons fight anime and shit like that. Most recent version is 1.1b, which adds dynamic stage cameras.

>Cool, how do I set it up?
There are thousands of guides on the internet on how to manually add characters, stages, and screenpacks (drag character folders into 'chars' folder, stage files into 'stages' folder ,screenpack files/folder into 'data' folder, etc.; then edit select.def), but if you want it to be done a bit easier, then use Vselect:

>What about online multiplayer?
Although base MUGEN does not have online multiplayer, a fork of MUGEN called IKEMEN has implemented online multiplayer. (Both players have to have the same IKEMEN full game for online to work properly)

>I want to make my own characters and stages.  Where do I start?
Well, you need to know how to code in the C language and use the SDL library to be able to make MUGEN content.  However, there is a program called Fighter Factory that makes it easier to  create and edit characters, stages, fonts, etc. by providing all the possible tools and functions.
