10	10
11		-You can create end-to-end encrypted personal or group chats that are not stored and dependent on a central authority like most other tools (ms teams, whatsapp, zoom, ...). All your messages are synced between all your devices - web clients, desktop clients, smartphone apps. For additional security, encryption keys of contacts can be verified and then stored as trusted.
	9	+* You need to register an account at a provider (e.g. tum.de, or lmu.de)
	10	+* Whatever your provider is, you can talk to people using other providers

	12	+For example {{code language="none"}}@someprofessor:tum.de{{/code}} can communicate with {{code language="none"}}@someresearcher:lmu.de{{/code}}!

	15	+In the same way you can use Outlook or Thunderbird with the same email account, you can use different Matrix apps for the same Matrix account!
	16	+Several apps exist, but we're going to go with "[[Element>>https://element.io/]]" for the sake of simplicity, as it's among the most fully-featured Matrix apps on the market.
