+
+## Install
+
+```sh
+npm install taskbuffer --save
+```
+
+## Concepts 
+
+### class `Task`
+* A Task in its most simple form is a function that is executed when the task runs.
+* A Task can have a **preTask** and an **afterTask**
+  (those are run before or after the main function whenever the task is called)
+* A Task can be buffered.
+  That means it can be called multiple times in a very short time.
+  However execution happens in line:
+  meaning execution of the task's main function is on halt until the previous task call has finished.
+  You can set bufferMax number, which is the max number of buffered task calls.
+  Any additional calls will then be truncated
+* Task.trigger() and Task.triggerBuffered() always return a Promise
+  which is fullfilled once the related task call has completed.
+* Task.triggered() is an Observable stream that emits events every time a task call is called and every time a call is completed.
+* Task is compatible to gulp streams.
+
+### class `TaskChain`
+* TaskChain extends Task.
+* Multiple Tasks can be combined in a bigger task using a TaskChain.
+* While the tasks are async in themselve, TaskChain **runs Tasks serialized** (one after the other)
+* that means that tasks can rely on each other and 
+
+### class `TaskParallel`
+* TaskParallel extends Task.
+* like TaskChain, however **tasks run in parallel**
+* Tasks cannot rely on each other.
+
+### Usage
+We highly recommend TypeScript as this module supports **TypeScript intellisense**.
+```javascript
+import * as taskbuffer from "taskbuffer";
+
+myTask = new taskbuffer.Task({
+  preTask: someOtherTask // optional, don't worry loops are prevented
+  afterTask: someOtherTask // optional, don't worry loops are prevented
+  name:"myTask1",
+  buffered: true, // optional
+  bufferMax: 3, // optional, call qeues greater than this are truncated
+  execDelay: 1000, // optional, time in ms to wait before executing task call
+  taskFunction:() => {
+    // do some stuff and return promise
+    // pass on any data through promise resolution
+    // Use TypeScript for better understanding and code completion
+  }
+})
+```
