Slimefun/Slimefun4

🧭 What Does Slimefun4 Actually Do? — A Plain-English Guide

In simple words: Slimefun4 is a small add-on that gives an existing program new powers, for changing and improving existing games. It is completely free and open source — its code is public on GitHub, where 1,137 people have bookmarked it as worth using.

Step by step — how you would actually use it

1. Slimefun4 does not work alone — it plugs into a bigger program, for example a browser, an editor or a design app.
2. Install that main program first, if you do not already use it.
3. Add Slimefun4 from the program's add-ons or plugins area, or by following the short steps in its README.
4. A new button, menu or feature appears inside the program you already know.
5. Use that new feature for changing and improving existing games — without learning a whole new program.

💡 A real-life example: A teenager with no budget uses a free engine like this to make their first small game and share it with friends.
