+To install `@push.rocks/lik`, you can use npm (Node Package Manager). Simply run the following command in your terminal:
+
+```bash
+npm install @push.rocks/lik --save
+```
+
+This will download `@push.rocks/lik` and add it to your project's `package.json` dependencies.
 
 ## Usage
 
-Use TypeScript for best in class instellisense.
+`@push.rocks/lik` is a versatile package offering a variety of helper classes designed to simplify common tasks in Node.js development. From managing asynchronous operations to handling collections efficiently, this library provides lightweight solutions to enhance your coding workflow. Below, we explore several key features of `@push.rocks/lik`, presenting TypeScript examples to demonstrate their practical application in real-world scenarios.
 
-```javascript
-// import any tool that you need from lik
-import { Stringmap, Objectmap, Observablemap } from 'lik';
+### AsyncExecutionStack
+
+`AsyncExecutionStack` allows for managing asynchronous task execution with exclusive and non-exclusive slots, ensuring effective handling of resource-intensive operations.
+
+```typescript
+import { AsyncExecutionStack } from '@push.rocks/lik';
+
+const myAsyncStack = new AsyncExecutionStack();
+
+// Exclusive execution ensures this task doesn't run in parallel with others
+await myAsyncStack.getExclusiveExecutionSlot(async () => {
+  // some asynchronous operation
+}, 2500);
+
+// Non-exclusive slots can run in parallel
+myAsyncStack.getNonExclusiveExecutionSlot(async () => {
+  // another asynchronous operation
+}, 1500);
 ```
 
-### class Stringmap
+### FastMap
 
-Stringmap allows you to keep track of strings. It allows you to register triggers for certain events
-like when a certain string is removed or added to the map
+`FastMap` offers a high-performance, key-value map optimized for rapid access and modifications, ideal for scenarios requiring frequent read/write operations.
 
-### class Objectmap
+```typescript
+import { FastMap } from '@push.rocks/lik';
 
-Sometimes you need to keep track of objects, but implementing logic for removing, finding or updating is tedious.
-Objectmap takes care of keeping track of objects for you.
+const myFastMap = new FastMap<string>();
 
-## Contribution
+// Add items
+myFastMap.addToMap('key1', 'value1');
+myFastMap.addToMap('key2', 'value2');
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+// Retrieve item
+const value = myFastMap.getByKey('key1'); // 'value1'

+### LimitedArray
 
-> MIT licensed | **&copy;** [Lossless GmbH](https://lossless.gmbh)
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+`LimitedArray` enforces a maximum size on an array, automatically managing its length to prevent it from exceeding a defined limit.
 
-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+```typescript
+import { LimitedArray } from '@push.rocks/lik';
+
+const myLimitedArray = new LimitedArray<number>(5); // limit size to 5
+
+myLimitedArray.addMany([1, 2, 3, 4, 5, 6]);
+console.log(myLimitedArray.array); // [2, 3, 4, 5, 6]
+```
+
+### LoopTracker
+
+`LoopTracker` helps detect and prevent infinite loops by tracking object references during iterations.
+
+```typescript
+import { LoopTracker } from '@push.rocks/lik';
+
+const myLoopTracker = new LoopTracker<object>();
+const obj1 = {};
+
+if (myLoopTracker.checkAndTrack(obj1)) {
+  // proceed with operation
+} else {
+  // potential loop detected
+}
+```
+
+### ObjectMap
+
+`ObjectMap` facilitates object management, providing functionalities for adding, finding, and removing objects with ease.
+
+```typescript
+import { ObjectMap } from '@push.rocks/lik';
+
+interface MyObject {
+  id: number;
+  name: string;
+}
+
+const myObjectMap = new ObjectMap<MyObject>();
+const obj: MyObject = { id: 1, name: 'Test Object' };
+
+// Add object
+myObjectMap.add(obj);
+
+// Find object
+const found = myObjectMap.findSync(item => item.id === 1);
+```
+
+### StringMap
+
+`StringMap` simplifies string collection management, allowing you to add, remove, and query strings effectively.
+
+```typescript
+import { Stringmap } from '@push.rocks/lik';
+
+const myStringMap = new Stringmap();
+
+// Add strings
+myStringMap.addString('hello');
+myStringMap.addStringArray(['world', 'example']);
+
+// Check string presence
+const exists = myStringMap.checkString('hello'); // true
+```
+
+### TimedAggregator
+
+`TimedAggregator` batches operations over a specified time interval, useful for aggregating logs, metrics, or any data points over time.
+
+```typescript
+import { TimedAggregtor } from '@push.rocks/lik';
+
+const myAggregator = new TimedAggregtor<string>({
+  aggregationIntervalInMillis: 5000, // 5 seconds
+  functionForAggregation: (items) => {
+    console.log('Aggregated items:', items);
+  }
+});
+
+// Add items
+myAggregator.add('item1');
+myAggregator.add('item2');
+
+// After 5 seconds, the functionForAggregation will log the aggregated items
+```
+
+### InterestMap and Tree
+
+`InterestMap` provides a structure for managing subscriptions or interests in certain events or entities, optimizing notification mechanisms.
+
+```typescript
+import { InterestMap } from '@push.rocks/lik';
+
+const myInterestMap = new InterestMap<string, number>((str) => str);
+
+myInterestMap.addInterest('event1').then((interest) => {
+  interest.fullfillInterest(42);
+});
+```
+
+`Tree` offers a way to handle hierarchical data structures, allowing for the composition and traversal of tree-like data sets.
+
+```typescript
+import { Tree } from '@push.rocks/lik';
+
+class TreeNode {
+  constructor(public value: string) {}
+}
+
+const myTree = new Tree<TreeNode>();
+const rootNode = new TreeNode('root');
+myTree.initialize(rootNode);
+
+// Add child nodes
+const childNode = new TreeNode('child');
+myTree.appendChild(rootNode, childNode);
+```
+
