# How to Install

### Download the manifest

The manifest file tells Excel where to find the add-in. Right-click the correct link below and select **Save link as**, then save it somewhere permanent — Excel needs the file to stay in the same location.

{% hint style="info" %}
Production Add-in: [tillit-add-in-prod.xml](https://tillit.cloud/excel-addin-v2/assets/manifests/tillit-add-in-prod.xml)
{% endhint %}

{% hint style="info" %}
Stage Add-in: [tillit-add-in-stage.xml](https://tillit.cloud/excel-addin-v2/assets/manifests/tillit-add-in-stage.xml)
{% endhint %}

{% hint style="warning" %}
Make a note of where you saved the file — you will need this path during installation.
{% endhint %}
