# Anchor IDL

The Squads MPL is built in Anchor, and can be found in the [Anchor Program Registry](https://www.apr.dev/program/SMPLecH534NA9acpos4G6x7uf3LWbCAwZQE9e8ZekMu). Developers can interact with the program using the standard TypeScript functionality outlined in the [Anchor TS Doc](https://coral-xyz.github.io/anchor/ts/index.html).

To get started, first make sure that the latest version of Anchor is added to your project.

```
// if  using yarn
yarn add @project-serum/anchor
// if using npm
npm install @project-serum/anchor
```
