​
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

git clone https://github.com/luisreindlmeier/gedonus.git
cd gedonus

​
Step 2 — Install dependencies

npm install

​
Step 3 — Start the dev server

npm start
This starts the local HTTPS dev server at https://localhost:3000 and opens the sideload flow for PowerPoint.
The first run will ask you to trust a self-signed certificate. Accept it so PowerPoint can load the add-in from localhost.

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

​
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.
