 ## Usage
 
-## Contribution
+This library is designed to facilitate graceful shutdowns in Node.js applications by allowing developers to easily perform cleanup operations (like closing database connections or stopping child processes) before the process exits. Below is a guide on integrating `@push.rocks/smartexit` using TypeScript.
 
-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). :)
+### Basic Setup
 
+First, import `SmartExit` from the package:
 
-## Contribution
+```typescript
+import { SmartExit } from '@push.rocks/smartexit';
+```

+### Registering Cleanup Functions
+
+`SmartExit` enables you to define custom cleanup functions that are executed before the process exits. These functions should return a promise to ensure all asynchronous cleanup operations complete successfully.
+
+```typescript
+smartExit.addCleanupFunction(async () => {
+  console.log("Performing custom cleanup...");
+  // Your cleanup operations here
+});
+```
+
+### Managing Child Processes
+
+It's common for a Node.js application to spawn child processes. `SmartExit` can also manage these, ensuring all child processes cleanly exit before the parent process exits.
+
+To add a child process to the management list:
+
+```typescript
+import { spawn } from 'child_process';
+
+const childProcess = spawn('your_child_process');
+smartExit.addProcess(childProcess);
+```
+
+If necessary, you can remove a previously added child process:
+
+```typescript
+smartExit.removeProcess(childProcess);
+```
+
+### Triggering Cleanup
+
+`SmartExit` automatically hooks into several process signal events (like `SIGTERM` and `SIGINT`) to start the cleanup procedure. However, you can manually trigger the cleanup and exit processes:
+
+```typescript
+await smartExit.killAll();
+process.exit(0); // or process.exit(1) to indicate an error state if needed
+```
+
+### Advanced Usage
+
+In more complex scenarios, you might need to conditionally add or remove cleanup functions and child processes, or integrate `SmartExit` with other libraries and frameworks for more comprehensive process management and shutdown procedures. Here you can leverage the full flexibility of JavaScript and TypeScript to tailor the shutdown behavior to your application's specific needs.
+
+#### Example: Shutdown on Uncaught Exceptions
+
+```typescript
+process.on('uncaughtException', async (error) => {
+  console.error("Uncaught Exception:", error);
+  await smartExit.killAll(); // Ensures all cleanup functions and child processes are managed
+  process.exit(1); // Exits with error
+});
+```
+
+#### Integrating with Express
+
+If your application uses Express, you might want to close the server gracefully:
+
+```typescript
+const server = app.listen(port, () => {
+  console.log(`Server started on port ${port}`);
+});
+
+smartExit.addCleanupFunction(async () => {
+  console.log("Closing Express server...");
+  await new Promise((resolve) => server.close(resolve));
+});
+```
+

+
+This documentation provides a foundational understanding of how to utilize `@push.rocks/smartexit` for managing graceful shutdowns in Node.js applications with TypeScript. Remember to adjust the code examples as necessary to fit your specific project requirements.
