 ## Getting started
 
 Note that the *dicom-microscopy-viewer* package is **not** a viewer application, it is a library to build viewer applications.
 
 Below is an example for the most basic usage: a web page that displays a collection of DICOM VL Whole Slide Microscopy Image instances of a digital slide.
-For more advanced usage, take a look at the [Slim](https://github.com/herrmannlab/slim) viewer.

 ### Basic usage
 
 The viewer can be embedded in any website, one only needs to
 
-* Create an instance of [VolumeImageViewer](https://herrmannlab.github.io/dicom-microscopy-viewer/viewer.VolumeImageViewer.html). The constructor requires an instance of `DICOMwebClient` for retrieving frames from the archive as well as the metadata for each DICOM image as an instance of [VLWholeSlideMicroscopyImage](https://herrmannlab.github.io/dicom-microscopy-viewer/metadata.VLWholeSlideMicroscopyImage.html).

 * Call the `render()` method, passing it the HTML element (or the name of the element), which shall contain the viewport.
