-## Introduction
+The BIMData Viewer displays models of many formats in a web page. Each format is
+handled by its own native built-in viewer, with **display**, **navigation**,
+**measurement** and **annotation** available on all of them.
-The BIMData Viewer is a tool for interacting with models of different formats like :
--
IFC
-- Image (PDF, PNG, JPG)
-- DWG
-- DXF
-- Point Cloud (PLY, LAS, LAZ).

-
-The BIMData Viewer is binded to the [BIMData API](/api/introduction/overview) and you can directly upload models using it or using the [BIMData platform](https://platform.bimdata.io/).
-
-[The UI can be customized](./guide/index#graphical-user-interface) to organize the workspace as you need and a flexible javascript API using
-[Vue 3](https://vuejs.org/) allows to create custom plugins to match your business perfectly.
-However, you don't need to master Vue.js to develop a plugin and you can still update the DOM with jQuery if you like!
+This guide takes you from an empty file to a model running in your browser. No
+account needed for the first step. Count about 15 minutes for the whole page.
-## Installation
+## See it running
-You can directly download the BIMDataViewer from a **CDN** or you can install the [`@bimdata/viewer` package](https://www.npmjs.com/package/@bimdata/viewer) using **NPM**.
+Create an `index.html` file, paste this, and open it. The identifiers below point
+to our public demo model, so it works as-is.
