# Presidio+ Help Center

Learn about Presidio+ and how it works with supported themes.

## Welcome to Presidio+

**Presidio+** is a companion app for [Presidio themes](/presidio-plus/how-presidio+-works.md#supported-themes) (and Horizon) that helps you build advanced storefront experiences without relying on multiple apps or custom development.

It combines app features, theme components, and sections into a single system for building your store and its functionality.

***

### What you can do with Presidio+

* Replace multiple Shopify apps with one integrated app: bundles, gift with purchase, buy X get Y, checkout text blocks, cutlines and more! 
* Add pre-built components and sections to your theme using the Element library
* Customize your storefront without needing custom code

***

### Theme support

Presidio+ includes the Headlands theme for free. Presidio+'s features and elements are designed to work best with Headlands.

You can also use the app with compatible [Presidio-built themes](/presidio-plus/how-presidio+-works.md#supported-themes) and Shopify’s default Horizon theme.

***

### How it works

Presidio+ is made up of three connected parts:

1. **App features**\
   You can create and manage storefront functionality like bundles and promotions directly in the app. These control how product experiences behave across your store.
2. **Theme components and sections**\
   You can install pre-built sections from the **Element library** into your Shopify theme. These enhance your storefront with new layouts and functionality without needing custom code.
3. **Headlands theme (optional)**\
   You can use a fully built Shopify theme included with Presidio+. It works seamlessly with all features and installed elements for a complete setup if you want it.
