 ## Usage
 
-Use TypeScript for best in class intellisense
+`@push.rocks/smartexpect` is a TypeScript library designed to manage expectations in your code effectively, improving testing readability and maintainability. Below are various scenarios showcasing how to use this library effectively across both synchronous and asynchronous code paths.
 
-## Contribution
+### Getting Started
 
-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). :)
+First, import `@push.rocks/smartexpect` into your TypeScript file:
 
-For further information read the linked docs at the top of this readme.
+```typescript
+import { expect, expectAsync } from '@push.rocks/smartexpect';
+```
 
-## Legal
+### Synchronous Expectations
-> MIT licensed | **©** [Task Venture Capital GmbH](https://task.vc)
+
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+You can employ `expect` to create synchronous assertions:
+
+```typescript
+import { expect } from '@push.rocks/smartexpect';
+
+// String type assertion
+expect('hello').toBeTypeofString();
+
+// Negated String type assertion
+expect(1).not.toBeTypeofString();
+
+// Boolean type assertion
+expect(true).toBeTypeofBoolean();
+
+// Equality assertion
+expect('hithere').toEqual('hithere');
+
+// Deep equality assertion
+expect({ key: 'value' }).toEqual({ key: 'value' });
+
+// Regular expression matching
+expect('hithere').toMatch(/hi/);
+```
+
+### Asynchronous Expectations
+
+For asynchronous operations, use `expectAsync` to return a promise:
+
+```typescript
+import { expectAsync } from '@push.rocks/smartexpect';
+
+const asyncStringFetcher = async (): Promise<string> => {
+  return 'async string';
+};
+
+const asyncTest = async () => {
+  await expectAsync(asyncStringFetcher()).toBeTypeofString();
+  await expectAsync(asyncStringFetcher()).toEqual('async string');
+};
+
+asyncTest();
+```
+
+### Advanced Usage
+
+- **Properties and Deep Properties:** Assert the existence of properties and their values.
+  
+  ```typescript
+  const testObject = { level1: { level2: 'value' } };
+
+  // Property existence
+  expect(testObject).toHaveProperty('level1');
+  
+  // Deep Property existence
+  expect(testObject).toHaveDeepProperty(['level1', 'level2']);
+  ```
+
+- **Conditions and Comparisons:** Allow more intricate assertions like greater than, less than, or matching specific conditions.
+
+  ```typescript
+  // Greater Than
+  expect(5).toBeGreaterThan(3);
+
+  // Less Than
+  expect(3).toBeLessThan(5);
+
+  // Custom conditions
+  expect(7).customAssertion(value => value > 5, 'Value is not greater than 5');
+  ```
+
+- **Arrays and Objects:** Work seamlessly with arrays and objects, checking for containment, length, or specific values.
+
+  ```typescript
+  const testArray = [1, 2, 3];
+
+  // Containment
+  expect(testArray).toContain(2);
+
+  // Array length
+  expect(testArray).toHaveLength(3);
+
+  // Object matching
+  expect({ name: 'Test', value: 123 }).toMatchObject({ name: 'Test' });
+  ```
+
+### Handling Promises and Async Operations
+
+`@push.rocks/smartexpect` gracefully integrates with asynchronous operations, providing a `expectAsync` function that handles promise-based assertions. This keeps your tests clean and readable, irrespective of the nature of the code being tested.
+
+### Best Practices
+
+- **Readability:** Favor clarity and readability by explicitly stating your expectations. `@push.rocks/smartexpect`'s API is designed to be fluent and expressive, making your tests easy to write and, more importantly, easy to read.
+
+- **Comprehensive Coverage:** Utilize the full spectrum of assertions provided to cover a broad set of use cases, ensuring your code behaves as expected not just in ideal conditions but across various edge cases.
+
+- **Maintainability:** Group related assertions together to improve test maintainability. This makes it easier to update tests as your codebase evolves.
+
+Through judicious use of `@push.rocks/smartexpect`, you can enhance the reliability and maintainability of your test suite, making your codebase more robust and your development workflow more efficient.
