# Installation

> Get Gedonus running inside PowerPoint in about five minutes.

## Prerequisites

* **Node.js** 18 or later
* **PowerPoint** (desktop, not web)
* **Git**

No Gedonus account needed. Everything runs on your machine.

***

## Step 1 — Clone the repository

```bash theme={null}
git clone https://github.com/luisreindlmeier/gedonus.git
cd gedonus
```

***

## Step 2 — Install dependencies

```bash theme={null}
npm install
```

***

## Step 3 — Start the dev server

```bash theme={null}
npm start
```

This starts the local HTTPS dev server at `https://localhost:3000` and opens the sideload flow for PowerPoint.

<Tip>
  The first run will ask you to trust a self-signed certificate. Accept it so PowerPoint can load the add-in from localhost.
</Tip>

***

## Step 4 — Sideload into PowerPoint

1. Open **PowerPoint** (desktop).
2. Go to **Insert → Add-ins → My Add-ins → Upload My Add-in**.
3. Select the `manifest.xml` file from the root of the repository.
4. The **Gedonus** task pane will appear on the right side.

<Note>
  You only need to sideload once. After that, Gedonus loads automatically every time you open PowerPoint — as long as the dev server is running.
</Note>

***

## Step 5 — Take your first version snapshot

1. Open any `.pptx` file in PowerPoint.
2. In the Gedonus task pane, click **Save version**.
3. Add a short message (e.g. `Initial version`) and confirm.

Your first version is saved locally. No data leaves your machine.
