 The __Events & Training__ section contains a community-sourced collection of events and training opportunities relevant for data-driven life science research.
 
-Each item displayed in the section Events & Training is stored as a file inside the `/content/events/` folder. Each file should be named with the start date of event using the following format: `20060102.md` which stands for January 2nd 2006. Each file should have extension `.md` but contain data in YAML format as shown below. The file starts and ends with lines containing three dashes. The lines between contain information about the event/training opportunity. Not all fields are obligatory (see below for which fields are obligatory).
+All the events displayed in the section Events & Training are stored in a `JSON` file [ddls_events.json](https://blobserver.dc.scilifelab.se/blob/ddls_events.json/info) in DC's `blobserver`. Each event/training is an object item in the `items` list, so to add a new event/training one should add a new object with required information (see below for the required fields).
