## Overview

The Graph is home to thousands of Subgraphs already available for query, so check [The Graph Explorer](/content/explorer/index.html) and find one that already matches your needs.

When you create a [Subgraph](/content/docs/en/subgraphs/developing/subgraphs/index.html), you create a custom open API that extracts data from a blockchain, processes it, stores it, and makes it easy to query via GraphQL.

Subgraph development ranges from simple scaffold Subgraphs to advanced, specifically tailored Subgraphs.

### Start Building

Start the process and build a Subgraph that matches your needs:

1. [Install the CLI](/content/docs/en/subgraphs/developing/creating/install-the-cli/index.html) - Set up your infrastructure
2. [Subgraph Manifest](/content/docs/en/subgraphs/developing/creating/subgraph-manifest/index.html) - Understand a Subgraph’s key component
3. [The GraphQL Schema](/content/docs/en/subgraphs/developing/creating/ql-schema/index.html) - Write your schema
4. [Writing AssemblyScript Mappings](/content/docs/en/subgraphs/developing/creating/assemblyscript-mappings/index.html) - Write your mappings
5. [Advanced Features](/content/docs/en/subgraphs/developing/creating/advanced/index.html) - Customize your Subgraph with advanced features

Explore additional [resources for APIs](/content/docs/en/subgraphs/developing/creating/graph-ts/README/index.html) and conduct local testing with [Matchstick](/content/docs/en/subgraphs/developing/creating/unit-testing-framework/index.html).
