 Although the EMo Viewer is designed as a generic viewer for digital editions, it is currently developed within the scope of the [Ahiqar project](https://gitlab.gwdg.de/subugoe/ahiqar).
 This is the reason for "Ahiqar" being mentioned several times in the docs of this repo.

+## Connecting the Viewer with a Backend
+
+The viewer expects JSON that complies to the [SUB's generic TextAPI](https://subugoe.pages.gwdg.de/emo/text-api/) in order to function properly.
+To establish a link to the backend, the viewer's entrypoint in `src/index.template.html` has to be modified:
+
+```html
+"entrypoint": "https://{server}{/prefix}/{collection}/collection.json"
+```
+
+The entrypoint should point to the collection you want to be displayed.
