 KAU holds quite a big collection of projects, with the intent on making it easy to reuse complex features, and also to update.
 This plugin aims to help maintain version updates straight from the source, and also adds on a few nice functions.
 
-As a note, this is located under `buildSrc` as it is automatically included when building KAU.

 ## Usage
 
-Firstly, add KAU to the buildscript:
+The easiest way to use this is to create your own `buildSrc` folder, and include `ca.allanwang.kau:gradle-plugin:${KAU}` as a dependency.
+This way, you can also use items in your buildscript.
+You can also add your own classes to manage versions in your app.
 
-```gradle
-buildscript {
-    repositories {
-        ...
-        maven { url "https://jitpack.io" }
-    }
-
-    dependencies {
-        ...
-        classpath "ca.allanwang:kau:${KAU}"
-    }
-}
-```
-
-Then where necessary, apply the plugin using
-
-```gradle
-apply plugin: 'ca.allanwang.kau'
-```
-
-# Versions
-
-> [Versions.groovy](/buildSrc/src/main/groovy/ca/allanwang/kau/Versions.groovy)
-
-Contains the version code for any external library used in KAU.
-You are free to use the values through `kau.[tagName]`.
-
-As an example, AppCompat is imported in KAU using
+When making your own `buildSrc`, make sure you add the jitpack repository:
 
 ```gradle
-api "androidx.appcompat:appcompat:${kau.appcompat}"
+repositories {
+    ...
+    maven { url "https://jitpack.io" }
+}
 ```
 
-# Plugins
+---
 
-> [Plugins.groovy](/buildSrc/src/main/groovy/ca/allanwang/kau/Plugins.groovy)
+Currently, the plugin is a collection of simple classes.
 
-Unfortunately, it seems like you can't use the plugin directly in the buildscript, so this is mainly internal.
+## Constants
 
-The plugins data, found using `kauPlugins.[tagName]` contains a collection of useful plugin classpaths.
-The versions are taken from `Versions.groovy`, so it is always in sync.
+`Versions`, `Plugins`, and `Dependencies` supply constants you can use for your classpath and dependencies
 
-# Dependencies
-
-> [Dependencies.groovy](/buildSrc/src/main/groovy/ca/allanwang/kau/Dependencies.groovy)
-
-Contains the dependency string for common libraries.
-You are free to use the values through `kauDependency.[tagName]`.
-
-As an example, adding junit can be done through
+Eg
 
 ```gradle
-testImplementation kauDependency.junit
+dependencies {
+    ...
+    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:${kau.Versions.coroutines}"
+}
 ```

 In conjunction with [core](/core#changelog-xml), 
 the xml changelog can be converted to markdown.

 After Material Dialog 2.x, a decision was made to enforce theming through xml styles only to avoid reflection.
 As a result, options to supply custom dialog colors are now removed (ie in the changelog dialog and color picker kprefs).
 
-## Update ProgressAnimator
+## ProgressAnimator
 
 `ProgressAnimator` has been completely rewritten to be an extension of `ValueAnimator`.
 This for the most part is not a breaking change, apart from the fact that creating an animator will not start it immediately.
 Make sure to call `.start()` to begin the animation.
 
+## Gradle Plugin
+
+The plugin has been converted to kotlin objects.
+Now, usage is done through the classes directly, and no extensions are provided within the project.
+For instance, instead of using `kauDependencies`, we now use `kau.Dependencies`.
+There is also no longer a need to use `apply plugin 'ca.allanwang.kau'`;
+adding the plugin to the classpath suffices.
+
 # v4.0.1-alpha02
 
 * `kauParseFaq` is now synchronous.
