What plugin is responsible for "Some Text-Widget"?

I am in the middle of preparing a small website on this CMS and I wanted to get rid of the text-widget on the side in the blog section. I would be very grateful for some pointers.

Look in the Antimatimatter's templates/partials/sidebar.html.twig It's basically just hard coded in there.

Thanks man! I'll be sure to go further in the docs to learn more about your CMS. I'm a big fan of your CMS as well as two others that happen to support Markdown. I wish you the best and I hope (since I'm a budding web dev student) to eventually get to Javascript and PHP soon so I can contribute maybe with some new themes :) Again thanks for your work!
