+Serpentity is a simple entity framework inspired by Ash.
+
+Usage:
+
+ const Serpentity = require('serpentity');
+
+## Instantiating an engine
+
+ const engine = new Serpentity();
+
+Add entities or systems, systems are added with a priority (the smaller
+the number, the earlier it will be called):
+
+ engine.addEntity(entityFactory());
+ engine.addSystem(new GameSystem(), priority);
+
+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.
+
+ const 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"
+
+ const PositionComponent = class PositionComponent extends Serpentity.Component {
+ constructor(config) {
+
+ this.x = 0;
+ this.y = 0;
+
+ super(config);
+ }
+ };
+
+You can add components to entities by using the add method:
+
+ entity.addComponent(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.
+
+ const MovementNode = class MovementNode extends Serpentity.Node;
+ MovementNode.position = PositionComponent;
+ MovementNode.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.
+
+ const TestSystem = class TestSystem extends Serpentity.System {
+ added(engine){
+
+ this.nodeList = engine.getNodes(MovementNode);
+ }
+
+ removed(engine){
+
+ this.nodeList = undefined;
+ }
+
+ update(dt){
+
+ for (const node of this.nodeList) {
+ console.log(`Current position is: ${node.position.x},${node.position.y}`);
+ }
+ }
+ };
