 # Serpentity
 
-Serpentity is a simple entity framework inspired by Ash.
+Serpentity has moved!
 
-Usage:
+Check out: [@serpentity/serpentity][serpentity-package]
 
-    require('serpentity');
+This package will stay at 2.0.0 (initial release of
+@serpentity/serpentity) but won't receive further updates.
 
-## Instantiating an engine
-
-    var engine = Serpentity();
-
-Add entities or systems:
-
-    engine.addEntity(entityFactory());
-    engine.addSystem(new GameSystem());
-
-Update all systems:
-
-    engine.update(dt);
-
-Remove entities or systems:
-
-    engine.removeEntity(entityReference);
-    engine.removeSystem(systemReference);
-
-## Creating Entities
-
-Entities are the basic object of Serpentity, and they do nothing.
-
-    var entity = new Serpentity.Entity();
-
-All the behavior is added through components
-
-## Creating Components
-
-Components define data that we can add to an entity. This data will
-eventually be consumed by "Systems"
-
-    Class("PositionComponent").inherits(Serpentity.Component)({
-        prototype : {
-            x : 0,
-            y : 0
-        }
-    });
-
-You can add components to entities by using the add method:
-
-    entity.add(new PositionComponent());
-
-
-Systems can refer to entities by requesting nodes.
-
-## Working with Nodes
-
-Nodes are sets of components that you define, so your system can require
-entities that always follow the API defined in the node.
-
-    Class("MovementNode").inherits(Serpentity.Node)({
-        types : {
-            position : PositionComponent,
-            motion : MotionComponent
-        }
-    });
-
-You can then request an array of all the nodes representing entities
-that comply with that API
-
-    engine.getNodes(MovementNode);
-
-## Creating Systems
-
-Systems are called on every update, and they use components through nodes.
-
-    Class("TestSystem").inherits(Serpentity.System)({
-        prototype : {
-            added : function added(engine){
-                this.nodeList = engine.getNodes(MovementNode);
-            },
-            removed : function removed(engine){
-                this.nodeList = undefined;
-            }
-            update : function update(dt){
-                this.nodeList.forEach(function (node) {
-                    console.log("Current position is: " + node.position.x + "," + node.position.y);
-                });
-            }
-        }
-    });
-
-## That's it
-
-Just run `engine.update(dt)` in your game loop :D
-
-## TO-DO
-
-* Removing components
-* Implement the ashteroids demo (Serpentoids)
-* Actually check performance
