 ## Usage
 
-Use TypeScript for best in class intellisense
+`@push.rocks/smartclickhouse` is an advanced ODM (Object Document Mapper) module designed for seamless interaction with ClickHouse databases leveraging the capabilities of TypeScript for strong typing and enhanced developer experience. Below is a comprehensive guide to using the package in various scenarios.
 
-## Contribution
+### Setting Up and Starting the Connection
 
-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). :)
+To begin using `@push.rocks/smartclickhouse`, you need to establish a connection with the ClickHouse database. This involves creating an instance of `SmartClickHouseDb` and starting it:
 
-For further information read the linked docs at the top of this readme.
+```typescript
+import { SmartClickHouseDb } from '@push.rocks/smartclickhouse';
 
-> MIT licensed | **©** [Lossless GmbH](https://lossless.gmbh)
-| By using this npm module you agree to our [privacy policy](https://lossless.gmbH/privacy)
+// Create a new instance of SmartClickHouseDb with your ClickHouse database details
+const dbInstance = new SmartClickHouseDb({
+  url: 'http://localhost:8123', // URL of ClickHouse instance
+  database: 'yourDatabase',     // Database name you want to connect to
+  username: 'default',          // Optional: Username for authentication
+  password: 'password',         // Optional: Password for authentication
+  unref: true                   // Optional: Allows service to exit while awaiting database startup
+});
 
-[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
+// Start the instance to establish the connection
+await dbInstance.start();
+```
+
+### Working with Time Data Tables
+
+`smartclickhouse` allows handling of time-series data through `TimeDataTable`, automating tasks such as table creation and data insertion.
+
+#### Creating or Accessing a Table
+
+To create a new time data table or access an existing one:
+
+```typescript
+const tableName = 'yourTimeDataTable'; // Name of the table you want to access or create
+const table = await dbInstance.getTable(tableName);
+```
+
+#### Adding Data to the Table
+
+Once you have the table instance, you can insert data into it:
+
+```typescript
+await table.addData({
+  timestamp: Date.now(),       // Timestamp in milliseconds
+  message: 'A log message.',   // Arbitrary data field
+  temperature: 22.5,           // Another example field
+  tags: ['tag1', 'tag2']       // An example array field
+});
+```
+
+The `addData` method is designed to be flexible, allowing insertion of various data types and automatically managing table schema adjustments.
+
+### Advanced Usage and Custom Data Handling
+
+`smartclickhouse` supports custom data types and complex data structures. For instance, to add support for nested objects or custom data processing before insertion, you might need to extend existing classes or customize the `addData` method to fit your needs.
+
+#### Custom Data Processing
+
+To handle complex data structures or to perform custom data processing before insertion, you might need to modify the `addData` method. Below is an example of extending the `SmartClickHouseDb` method:
+
+```typescript
+class CustomClickHouseDb extends SmartClickHouseDb {
+  public async addCustomData(tableName: string, data: any) {
+    const table = await this.getTable(tableName);
+    const customData = {
+      ...data,
+      processedAt: Date.now(),
+      customField: 'customValue',
+    };
+    await table.addData(customData);
+  }
+}
+
+const customDbInstance = new CustomClickHouseDb({
+  url: 'http://localhost:8123',
+  database: 'yourDatabase',
+});
+
+await customDbInstance.start();
+
+await customDbInstance.addCustomData('customTable', {
+  message: 'Test message',
+  randomField: 123456,
+});
+```
+
+### Bulk Data Insertion
+
+`@push.rocks/smartclickhouse` supports efficient bulk data insertion mechanisms. This feature is useful when you need to insert a large amount of data in a single operation.
+
+```typescript
+const bulkData = [
+  { timestamp: Date.now(), message: 'Message 1', temperature: 20.1 },
+  { timestamp: Date.now(), message: 'Message 2', temperature: 21.2 },
+  // Additional data entries...
+];
+
+await table.addData(bulkData);
+```
+
+### Querying Data
+
+Fetching data from the ClickHouse database includes operations such as retrieving the latest entries, entries within a specific timestamp range, or streaming new entries.
+
+#### Retrieving the Last N Entries
+
+To retrieve the last `N` number of entries:
+
+```typescript
+const latestEntries = await table.getLastEntries(10);
+console.log('Latest Entries:', latestEntries);
+```
+
+#### Retrieving Entries Newer than a Specific Timestamp
+
+To retrieve entries that are newer than a specific timestamp:
+
+```typescript
+const timestamp = Date.now() - 60000; // 1 minute ago
+const newEntries = await table.getEntriesNewerThan(timestamp);
+console.log('New Entries:', newEntries);
+```
+
+#### Retrieving Entries Between Two Timestamps
+
+To retrieve entries between two timestamps:
+
+```typescript
+const startTimestamp = Date.now() - 120000; // 2 minutes ago
+const endTimestamp = Date.now() - 5000; // 5 seconds ago
+const entriesBetween = await table.getEntriesBetween(startTimestamp, endTimestamp);
+console.log('Entries Between:', entriesBetween);
+```
+
+### Managing and Deleting Data
+
+The module provides functionality for managing and deleting data within the ClickHouse database.
+
+#### Deleting Old Entries
+
+You can delete entries older than a specified number of days:
+
+```typescript
+// Ensure there are entries before deletion
+let entries = await table.getLastEntries(1000);
+console.log('Entries before deletion:', entries.length);
+
+// Delete all entries older than now
+await table.deleteOldEntries(0);
+
+// Verify the entries are deleted
+entries = await table.getLastEntries(1000);
+console.log('Entries after deletion:', entries.length);
+```
+
+#### Deleting the Entire Table
+
+To delete the entire table and all its data:
+
+```typescript
+await table.delete();
+
+// Verify table deletion
+const result = await dbInstance.clickhouseHttpClient.queryPromise(`
+  SHOW TABLES FROM ${dbInstance.options.database} LIKE '${table.options.tableName}'
+`);
+console.log('Table exists after deletion:', result.length === 0);
+```
+
+### Observing Real-Time Data
+
+To observe new entries in real-time, you can stream new data entries using the RxJS Observable:
+
+```typescript
+const stream = table.watchNewEntries();
+
+const subscription = stream.subscribe((entry) => {
+  console.log('New entry:', entry);
+});
+
+// Simulate adding new entries
+let i = 0;
+while (i < 10) {
+  await table.addData({
+    timestamp: Date.now(),
+    message: `streaming message ${i}`,
+  });
+  i++;
+  await new Promise((resolve) => setTimeout(resolve, 1000)); // Add a delay to simulate real-time data insertion
+}
+
+subscription.unsubscribe();
+```
+
+This method allows continuous monitoring of data changes and integrating the collected data into other systems for real-time applications.
+
+### Comprehensive Feature Set
+
+While the examples provided cover the core functionalities of the `@push.rocks/smartclickhouse` module, it also offers a wide range of additional features, including:
