# Upload Experiences from Unity

Use this page to upload a prepared Unity experience to Bridge XR.

### Before you upload

Make sure:

* your Unity project already includes **Zoe for Unity**
* the **Bridge XR integration package** is installed
* **tracking** and **completion** actions are configured
* you have your **developer credentials**
* you have the **Bridge XR server URL** from your IT team

### Step 1: open the Bridge Wizard

In Unity, open:

`BridgeXR > Wizard`

Then sign in with your developer credentials.

The **Main Scene** is the first Unity scene in your experience.

Additional scenes are any scenes loaded from the main scene with Zoe for Unity.

### Upload the bundles

1. Click **Upload All Bundles**.
2. Wait while the wizard builds the bundles.
3. Confirm the success notification appears.

### Update an existing experience

To update an experience:

1. Open the Bridge Wizard.
2. Select the experience from the list.
3. Update the general information, add a platform, or replace an existing bundle.
4. Click **Upload All Bundles** again.

{% hint style="info" %}
To update an existing platform, you must override the existing bundle.

The wizard increments the experience version automatically each time you upload new bundles.
{% endhint %}

{% hint style="warning" %}
The wizard checks the bundle during upload, but a bundle can still become corrupted during transfer.

If that happens, updating the same instance may not solve it. You may need to generate a new experience instance.
{% endhint %}

### Next step

After upload, continue with [Test Published Experiences](/bridge-xr/build-with-unity/test-published-experiences.md).
