+# Basic Style Dictionary
+
+This example code is bare-bones to show you what this framework can do. If you have the style-dictionary module installed globally, you can `cd` into this directory and run:
+```bash
+style-dictionary build
+```
+
+You should see something like this output:
+```
+Copying starter files...
+
+Source style dictionary starter files created!

+Running `style-dictionary build` for the first time to generate build artifacts.

+Good for you! You have now built your first style dictionary! Moving on, take a look at what we have built. This should have created a build directory and it should look like this:
+```

+│   ├── color/
+│       ├── base.json

+
+If you open `config.json` you will see there are 5 platforms defined: scss, android, compose, ios, and ios-swift. Each platform has a transformGroup, buildPath, and files. The buildPath and files of the platform should match up to the files what were built. The files built should look like these:
+
+**Android**
+```xml
+<!-- font_dimens.xml -->
+<resources>
+  <dimen name="size_font_small">12.00sp</dimen>
+  <dimen name="size_font_medium">16.00sp</dimen>
+  <dimen name="size_font_large">32.00sp</dimen>
+  <dimen name="size_font_base">16.00sp</dimen>
+</resources>
+
+<!-- colors.xml -->
+<resources>
+  <color name="color_base_gray_light">#ffcccccc</color>
+  <color name="color_base_gray_medium">#ff999999</color>
+  <color name="color_base_gray_dark">#ff111111</color>
+  <color name="color_base_red">#ffff0000</color>
+  <color name="color_base_green">#ff00ff00</color>
+  <color name="color_font_base">#ffff0000</color>
+  <color name="color_font_secondary">#ff00ff00</color>
+  <color name="color_font_tertiary">#ffcccccc</color>
+</resources>
+```
+
+**Compose**
+```kotlin
+object StyleDictionaryColor {
+  val colorBaseGrayDark = Color(0xff111111)
+  val colorBaseGrayLight = Color(0xffcccccc)
+  val colorBaseGrayMedium = Color(0xff999999)
+  val colorBaseGreen = Color(0xff00ff00)
+  val colorBaseRed = Color(0xffff0000)
+  val colorFontBase = Color(0xffff0000)
+  val colorFontSecondary = Color(0xff00ff00)
+  val colorFontTertiary = Color(0xffcccccc)
+}
+
+object StyleDictionarySize {
+  /** the base size of the font */
+  val sizeFontBase = 16.00.sp
+  /** the large size of the font */
+  val sizeFontLarge = 32.00.sp
+  /** the medium size of the font */
+  val sizeFontMedium = 16.00.sp
+  /** the small size of the font */
+  val sizeFontSmall = 12.00.sp
+}
+```
+
+**SCSS**
+```scss
+// variables.scss
+$color-base-gray-light: #cccccc;
+$color-base-gray-medium: #999999;
+$color-base-gray-dark: #111111;
+$color-base-red: #ff0000;
+$color-base-green: #00ff00;
+$color-font-base: #ff0000;
+$color-font-secondary: #00ff00;
+$color-font-tertiary: #cccccc;
+$size-font-small: 0.75rem;
+$size-font-medium: 1rem;
+$size-font-large: 2rem;
+$size-font-base: 1rem;
+```
+
+**iOS**
+```objc
+#import "StyleDictionaryColor.h"
+
+@implementation StyleDictionaryColor
+
++ (UIColor *)color:(StyleDictionaryColorName)colorEnum{
+  return [[self values] objectAtIndex:colorEnum];
+}
+
++ (NSArray *)values {
+  static NSArray* colorArray;
+  static dispatch_once_t onceToken;
+
+  dispatch_once(&onceToken, ^{
+    colorArray = @[
+[UIColor colorWithRed:0.800f green:0.800f blue:0.800f alpha:1.000f],
+[UIColor colorWithRed:0.600f green:0.600f blue:0.600f alpha:1.000f],
+[UIColor colorWithRed:0.067f green:0.067f blue:0.067f alpha:1.000f],
+[UIColor colorWithRed:1.000f green:0.000f blue:0.000f alpha:1.000f],
+[UIColor colorWithRed:0.000f green:1.000f blue:0.000f alpha:1.000f],
+[UIColor colorWithRed:1.000f green:0.000f blue:0.000f alpha:1.000f],
+[UIColor colorWithRed:0.000f green:1.000f blue:0.000f alpha:1.000f],
+[UIColor colorWithRed:0.800f green:0.800f blue:0.800f alpha:1.000f]
+    ];
+  });
+
+  return colorArray;
+}
+
+@end
+```
+
+Pretty nifty! This shows a few things happening:
+1. The build system does a deep merge of all the token JSON files defined in the `source` attribute of `config.json`. This allows you to split up the token JSON files however you want. There are 2 JSON files with `color` as the top level key, but they get merged properly.
+1. The build system resolves references to other design tokens. `{size.font.medium.value}` gets resolved properly.
+1. The build system handles references to token values in other files as well as you can see in `tokens/color/font.json`.
+
+Now let's make a change and see how that affects things. Open up `tokens/color/base.json` and change `"#111111"` to `"#000000"`. After you make that change, save the file and re-run the build command `style-dictionary build`. Open up the build files and take a look.
+
+**Huzzah!**
+
+Now go forth and create! Take a look at all the built-in [transforms](https://amzn.github.io/style-dictionary/#/transforms?id=pre-defined-transforms) and [formats](https://amzn.github.io/style-dictionary/#/formats?id=pre-defined-formats).
