# Product Overview

[**cheqd**](https://cheqd.io/) is a purpose-built network for decentralised identity. This documentation site provides **technical and product information** for all **identity features & functionality** on the cheqd network.

## Integrate with cheqd

cheqd maintains an array of products and packages with **varying levels of integration complexity** to allow its partners and customers to have multiple ways of plugging into cheqd's identity functionality. Via these different packages, customers and partners can create cheqd DIDs, DID-Linked Resources, Status Lists, Trust Registries and Schemas, as well as use cheqd's Credential Payments model.

There are three core ways of integrating and building with cheqd:

## What functionality does cheqd offer?

cheqd's identity functionality is fully standards-compliant, ensuring interoperability and no vendor lock-in. cheqd's tooling and different product offerings offer a variety of building blocks for any Trusted Data Market.

## Industry Standard DID Support

If you want to utilise cheqd DIDs or DID-Linked Resources within applications without a specific cheqd integration, you can incorporate a Universal Registrar or Universal Resolver driver to support `did:cheqd` alongside other commonly adopted DID methods.

## Get started with cheqd Studio

cheqd Studio is the easiest route to get started with cheqd's identity functionality, or for testing with very low integration effort. Using simple REST APIs, it is possible to integrate cheqd Studio in a few lines of code.

Under the hood, cheqd Studio utilises the [Veramo SDK cheqd Plugin](https://docs.cheqd.io/product/sdk/veramo), providing the most feature complete set of functionality and tooling.

If you'd rather build a deeper integration using a Software Development Kit (SDK) or lower level package, we've created a simple diagram to show how our packages are structured below.

## Understanding cheqd's capabilities

cheqd supports a wide array of standards and protocols via different Software Development Kits (SDKs) and integrations.

## Understanding the *structure* of cheqd's packages

One of cheqd's primary motives is to make itself accessible to the widest set of identity applications possible. To accomplish this, cheqd has built a **flexible set of packages and tooling** to accommodate its identity capabilities into a **broad set of external SDKs and applications**.&#x20;

These can be represented through the visual below:

## Partner SaaS products

You can also leverage SaaS products from our partners that consume these underlying SDKs to build high-quality credential ecosystems on top of cheqd’s infrastructure:
