# Quick Start

Welcome to Telemetry! Telemetry is a logging and analytics platform designed to help you capture, store, and query your data effortlessly. Whether you're tracking application metrics, monitoring user behavior, or analyzing business performance, Telemetry provides a seamless experience with consistent APIs across multiple programming languages.

If you're interested in learning more about how Telemetry works under the hood, check out our [Telemetry Architecture Doc](https://docs.telemetry.sh/discussion-topics/telemetry-architecture) for a detailed overview. For a more in-depth use case, such as tracking OpenAI costs by instrumenting API calls, refer to our guide on [Tracking OpenAI Costs](https://docs.telemetry.sh/guides/tracking-openai-costs).

## **Install Telemetry**

This tutorial uses JavaScript. For other languages, please refer to the individual SDKs. The overall API structure is consistent across different programming languages.

```
npm install telemetry-sh
```

## **Log some data**

Telemetry automatically creates tables when data is logged. In the following example, we log some Uber ride data to a table called `uber_rides`. Telemetry will automatically create this table and its corresponding schema with columns: `city`, `price`, and `timestamp`.

{% code overflow="wrap" lineNumbers="true" %}

```javascript
import telemetry from "telemetry-sh";

telemetry.init("YOUR_API_KEY");

telemetry.log("uber_rides", {
  city: "paris",
  price: 42,
  timestamp: new Date().toISOString()
});
```

{% endcode %}

## Explore data with our UI

You can do all sorts of different visualizations and queries in our interactive UI located at <https://telemetry.sh>.

## Query some data

You can integrate telemetry into your product or internal dashboards by querying the data using SQL through our query API.

{% code lineNumbers="true" %}

```javascript
const results = 
  await telemetry.query(`
    SELECT
      city,
      AVG(price)
    FROM
      uber_rides
    GROUP BY
      city
  `);
```

{% endcode %}
