# Develop Experiences in Unity

Use this page to prepare a Unity project for Bridge XR.

### What you need

Make sure you have:

* **Zoe for Unity**
* the **Bridge XR integration package**

{% hint style="info" %}
In many institutions, this work may be done by students, faculty teams, or external development partners.
{% endhint %}

### Step 1: install Zoe for Unity

Use the recommended Unity version for Zoe and follow the Zoe installation guide:

[Installing Zoe for Unity](/installation/installing-zoe-for-unity.md)

### Step 2: install the Bridge XR integration package

After Zoe is installed, add the **Bridge XR integration package** to the same Unity project.

This package connects your Unity project to Bridge XR.

It is used to:

* prepare uploads
* send analytics data
* report experience completion

### Step 3: build your experience with Zoe for Unity

Build your experience in Unity. Use this Help Center whenever needed. Test the experience in Unity until the core flow is stable.

### Step 4: add Bridge XR actions before upload

Before uploading, add the Bridge XR actions needed for tracking.

#### Add Bridge XR scripts

To add actions beyond the standard dropdown list:

1. Click **Add Component**.
2. Search for scripts that begin with `SA_`.

#### Add tracking

For every interaction you want to track, add:

* `SA_StatisticsAction`

#### Add completion reporting

To let Bridge XR know the experience is complete, add:

* `SA_CompleteAction`

Attach it to the interaction that marks the end of the experience.
