 Flat, simple, centralized UI toolkit for WinForms
 
 ![Example Screenshot](/screenshot.png)
+
+## How to use
+1) Add a reference to KUI.dll to your WinForms project
+2) Create a new windows form
+3) Add a reference to KUI in your form's cs file
+4) Change your form to extend "FlatWindow" instead of "Form".
+5) Use the KUI controls instead of the standard WinForms ones as you build your form.
+
+## How the theme works
+All windows and control pull their font size, color, back color, and fore color from the static Theme class.
+Note that the controls will completely ignore those noted properties set in the designer.
+To change the color theme, you can call:
+
+`Theme::SetFont(string fontName, int bodySize, int titleSize)`
+
+`Theme::SetFontColor(Color c)`
+
+`Theme::SetForeColor(Color c)`
+
+`Theme::SetBackColor(Color c)`
+
+`Theme::SetAccentColor(Color c)`
+
+`Theme::SetShadowSize(int size)`
+
+`Theme::SetShadowColor(Color c)`
+
+respectively. Changing these values will NOT cause an automatic update/redraw of your controls. So either call these methods before initializing any part of your forms, or invalidate your forms after changing them.
+
+## How the included windows work
+Each window extends `WindowBase`, which provides the base themeing element of the form as well as the shadow effect if you're using that.
+
+`FlatFrame` is intended to be used as a popup menu that can be docked using WinForm's standard docking feature. It provides nothing but a themed blank canvas.
+
+`FlatToolFrame` directly extends `FlatFrame` and additionally provides a header and footer bar.
+
+`FlatWindow` is a standalone window the provides support for resizing, dragging, and the standard Close, Maximize, Minimize buttons.
+
+## Left to do
+- Implement the rest of the most commonly used WinForms controls, such as Textbox, RichTextBox, etc.
+- Have theme changes cause redraws automatically
+- Have property changes cause invalidations on controls
+- Implement autosizing on controls like labels
+- Re-enable animations for frames after getting them to draw correctly
+- Implement the standard Visual Studio designer hooks
+- Implement more of the commonly used properties for the forms and controls, such as the ability to choose what window buttons are shown on the form
