+# Ghost's Utilities
+
+Ghost's Utilities or more known as GhostUtil is a module/addon to Psych Engine to make programming more easier and tidier.
+GhostUtil provides a lot of unique variables and functions for you to mess around!

+
+## The Basics
+
+### How do I use GhostUtil?
+* Add the "ghostutil" folder to the main Psych Engine folder. (where the `.exe` is)
+
+![image](https://github.com/GhostglowDev/Ghost-s-Utilities/assets/108509756/076a2654-46fd-4231-b4ba-2512f4ee880c)
+
+and then, drag-n-drop the `callbackhandler.lua` file to `mods/scripts`
+
+![image](https://github.com/GhostglowDev/Ghost-s-Utilities/assets/108509756/cf993438-85c4-447c-9cb0-0255ebf7a765)
+
+* To use GhostUtil, you must import it's modules; use the `require` function on a variable.
+Since we're using base lua functions, this is not needed to be in a function.
+

+
+* Let's try messing with the script!
+```lua
+local math = require "ghostutil.lua-addons.math"
+local game = require "ghostutil.Game"
+
+function onCreate()
+    luaDebugMode = true
+    game.doTweenScale("tweenScale", "boyfriend", {2, 2.1}, "expoOut")
+    game.doTweenPosition({"boyfriendcool", "boyfriendswag"}, "boyfriend", {
+        game.getPosition("boyfriend").x - 100,
+        math.boundto(game.getPosition("dad").y + 100, -100, 200)
+    }, 2, "expoOut")
+end
+```
+This does a tweens boyfriend's scale to 2x it's default size. It also tweens boyfriend's position!
+
+`math.boundto` was to limit the coordinates to reach a certain number
+
+### For more advanced informations:
+**CHECK OUT THE [WIKI](https://github.com/GhostglowDev/Ghost-s-Utilities/wiki) FOR MORE FUNCTIONS.**
+
+### Older Versions
+**Psych Engine**:
+
+* below 0.6.3:
+Mostly because most of the lua functions that GhostUtil use doesn't exist.
+
+ * 0.7.1h:
+It breaks GhostUtil (mostly because of `runHaxeCode`); so use the latest version or 0.7.3 instead.
+
+**GhostUtil**:
+
+* below 2.0.0a:
+When using the `Window` class, add `window.init()` before doing anything with the Window functions/variables
+"window" in `window.init()` depends on what you set the variable to. If it's `wind` then `wind.init()`, etc.
+
+
+* below 1.0.0:
+Naming the variable `math` will break the script.
