 ## Why use MARTINS.js?
 
 * **No need to download apps!** MARTINS.js is a WebAR engine. It runs in web browsers. Users can access the AR experience immediately.
 * **Fast and powerful!** MARTINS.js is GPU-accelerated. It uses WebGL2 and WebAssembly for turbocharged performance.
 * **No need of custom hardware or software!** MARTINS.js is built from scratch using standard web technologies. All it requires is a modern and compatible web browser.
-* **Fully standalone!** MARTINS.js has in it everything it needs to analyze the environment and help you create AR. There are no additional requirements. It's not WebXR.

     Fixing the orientation of the model is the preferred solution. However, you can also fix the issue with code: add a node (entity) to the scene graph and make it rotate its children by 90 degrees around the x-axis.

docs/getting-started/create-the-augmented-scene.md

 
 I provide easy-to-use glue codes that work with different 3D rendering technologies in my demos, so that you don't need to deal with the complexity. Those glue codes are JavaScript (.js) files. You just need to add a glue code to your web page (e.g., via a `<script>` tag) and then the integration will be done for you. It's really that simple! Also, my glue codes may be used in both free and non-free projects.

 ## Create the virtual scene
 
 Once you plug in the glue code, you'll be using the 3D rendering technology of your choice to create the virtual scene. The physical scene will be automatically augmented with the virtual scene, thus creating the augmented scene.
