+## About the project
+
+This is a demo of a custom Dashboard for IML Appmonitor using the API to fetch data. It works offline without a webserver using the Javascript fetch() function.
+
+The Dashboards reads the tags from the IML appmonitor. You can enable/ disable each existing tag. The application section shows the application status of matching apps. The view will be refreshed in the given interval.
