# Introduction

> What addons are, the kinds Unbound supports, and what they share.

An **addon** is something you install into Unbound to change Discord. They come in three kinds, but they're built and managed the same way: each ships a [manifest](/addons/manifest), is governed by the same [lifecycle](/modules/managers), and is enabled, disabled, and persisted through the same machinery.

### The kinds

<CardGroup cols={3}>
  <Card title="Plugins" icon="plug" href="/plugins/introduction">
    Code that runs. Add functionality by finding and patching Discord's internals.
  </Card>

  <Card title="Themes" icon="paintbrush" href="/themes/introduction">
    Data that restyles. A palette (and optional background) Unbound applies to the UI.
  </Card>

  <Card title="Icon Packs" icon="icons" href="/icon-packs/introduction">
    Image overrides. Swap Discord's built-in icons for your own.
  </Card>
</CardGroup>

### What every addon shares

<CardGroup cols={2}>
  <Card title="Creating an addon" icon="wand-magic-sparkles" href="/addons/creating">
    A step-by-step walkthrough of building one from an empty folder.
  </Card>

  <Card title="The manifest" icon="circle-info" href="/addons/manifest">
    The metadata every addon ships, and how it's validated.
  </Card>
</CardGroup>

<Note>
  Plugins are the richest kind and the rest of this section leans on them for examples, but the manifest, lifecycle, and enable/disable model are identical across all three. See [Managers](/modules/managers) for how that lifecycle works under the hood.
