-## Features targeted for 20.2.0.0-alpha.2
-* The stage subsystem
-    * A "stage", in this context, is a set of assets bound together
-    by programming logic, not necessarily a game level.
-    Stage switching and asset management are handled by the engine.
-    * Upon stage switch
-        1. Unload unused assets
-        2. Load new assets
-    * Provide multiple means of stage switching
-        * Three modes with the initial release
-            1. Instant switch
-                * Assets will be loaded and unloaded synchronously
-                * The stage switch will happen in one frame
-            2. Deferred switch
-                * The stage will continue running until all assets load
-                * Assets will load synchronously, but at a slower pace
-                to avoid frame stutter
-            3. Asynchronous switch
-                * Assets will be loaded in asynchronously, where applicable
-                * Falls back to deferred switching for synchronous loading, 
-                such as OpenGL texture upload              
-    * Automated asset loading
-        * All asset management will eventually be handled by `PlutoCore`
-            * This includes audio clips, textures, sprites
-        * Add a common interface for all assets
-    * Let the stage system handle audio playback
-    * This API should be as neutral as possible and avoid steering towards
-    game-only use
-    * The stage manager should be relatively low-overhead and allow multiple
-    instances
-    * Allow stages to be inherited from, creating a stack-like structure
-* The initial minimal release of `[PlutoCommandParser]`
-
-
-## Features targeted for 20.2.0.0-alpha.3
-* `[PlutoLib]` Completely redo the ModLoader system
-    * The current implementation is a result of 5 years of feature creep 
-    * Large scale API changes, however the general idea should stay the same
-    * Rethink the class loader system.
-* `[PlutoAudio]` Integrate the Audio API with the Stage API
-* Improve upon the support of thread-local Pluto instances
-    * The long term goal is to allow an unlimited amount of Pluto applications at any given time

+## How to use Pluto
+
+**Quick start**
+
+Download [the demo project](https://github.com/plutoengine/plutoengine-basic-demo) open it in IntelliJ IDEA.
+
+**Gradle**
+```groovy
+repositories {
+   mavenCentral()
+

+      url = uri("https://vega.botdiril.com/releases")

+}
+
+
+dependencies {
+   implementation group: "org.plutoengine", name: "plutocore", version: "22.3.0.0-alpha.0"
+}
+```
+
+**or for Gradle Kotlin DSL**
+```kotlin
+repositories {
+   mavenCentral()
+
+   maven {
+      name = "Vega"
+      url = uri("https://vega.botdiril.com/releases")

 ## Usability status of submodules
 
+Keep in mind PlutoEngine is in alpha and all features are tentative.
+The following list simply provides an overview of how likely breaking changes are to occur.
+
 ### Safe submodules
 * **PlutoCore** - Stable
- * **PlutoFramebuffer** - Stable
- * **PlutoGUI** - Stable, awaiting a rewrite
- * **PlutoLib** - Mostly stable, the module API still has some quirks
- * **PlutoMesher** - Stable
- * **PlutoShader** - Stable
- * **PlutoSpriteSheet** - Stable, some features are unfinished
- * **PlutoStatic** - Stable, collision API nowhere near completion
+* **PlutoSpritesheet** - Stable, some features are unfinished
+* **PlutoDisplay** - Stable, collision API nowhere near completion
+* **PlutoLib** - Mostly stable
+* **PlutoRender** - Stable
+* **PlutoRuntime** - Mostly stable
 
 ### Unstable submodules
- * **PlutoAudio** - Somewhat usable, unfinished
+* **PlutoAudio** - Very tentative, work in progress
+* **PlutoGUI** - Recently rewritten, the API is highly unstable, work in progress
+
+### Extensions
+* **PlutoUSS2** - Stable
+* **PlutoGameObject** - Stable
 
-### Broken submodules, do NOT use
- * **PlutoCommandParser** - Unfinished, broken, unusable
- * **PlutoDB** - Broken, unusable
 
 ## Current priorities
 
-### Very high priority
- * Finish PlutoAudio
-    * Depends on the stage system
- * The stage system and automated asset loading
- * Rewrite the ModLoader
- * Finish PlutoCommandParser
- 
-### High priority
- * Streamline PlutoLib, remove bad APIs and improve code quality
- 
-### Normal priority
- * Rewrite PlutoGUI
- * The collision system for PlutoStatic
- * Improve image loading capabilities, possibly rewrite PlutoLib#TPL
- 
-### Low priority
- * Allow multiple running instances of Pluto
-    * Alternatively, if this deems too difficult to implement,
-    prohibit the creation of more than instance per VM to avoid issues
- * A networking API
+See [issues](https://github.com/493msi/plutoengine/issues) for details.
