# Accelerators Overview

> Add-on packages that extend fusionCore beyond the base product — install separately, configure, and use alongside your org.

## What Are Accelerators?

**Accelerators** are add-on Salesforce packages that are not included in the base fusionCore install. Each one is installed separately, on top of fusionCore (or, for a few, on top of base Salesforce without fusionCore at all). Each page in this section covers one accelerator: what it does, how to configure it, and the limitations and common pitfalls to know before you rely on it.

<Info>
  If you're not sure whether an accelerator is installed in your org, check **Setup → Installed Packages** before following its configuration steps.
