9 -Matrix is a chat system very similar to E-Mail. People have their account on one server but can write messages to anyone on other servers. For example @someprofessor:tum.de can communicate with @someresearcher:lmu.de.
7 +[[Matrix>>https://matrix.org/]] is a chat system very similar to E-Mail, but instantaneous and secure.

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
11 +** (((
12 +For example {{code language="none"}}@someprofessor:tum.de{{/code}} can communicate with {{code language="none"}}@someresearcher:lmu.de{{/code}}!
13 +)))
14 +* (((
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.
17 +)))

13 -You can use either the desktop version or the web interface of matrix.
19 +So People have their **account on one server** but can write messages **to anyone on other servers**.

22 +You can create[[ end-to-end encrypted>>https://en.wikipedia.org/wiki/End-to-end_encryption]] **personal or group chats** that are not stored and **not dependent on a central authority** like most other tools (MS Teams, WhatsApp, Zoom, ...).
23 +All your messages are **synced** between all your devices - web clients, desktop clients, smartphone apps.
24 +For additional security, encryption keys of contacts can be verified and then stored as trusted.
25 +
26 +== Home Server ==
27 +
28 +Messages are stored and synced between home servers.
29 +
30 +A user typically has **one account** on one homeserver. You can use any homeserver of your choice - however [[ITO>>doc:CIT.ITO.WebHome]] offers two homeservers:
31 +
32 +* **matrix.cit.tum.de** for CIT accounts: @username:cit.tum.de
33 +* **matrix.tum.de** for TUM accounts: @username:tum.de
34 +
35 +You only need to use one account and can communicate with any other homeserver of the world.
36 +
37 +If you don't have a CIT or TUM account, you can use a public homeserver instead:
38 +
39 +* matrix.org: [[https:~~/~~/app.element.io/#/register>>https://app.element.io/#/register]]
40 +* or any other homeserver [[https:~~/~~/joinmatrix.org/servers/>>https://joinmatrix.org/servers/]]
41 +* or, host your own homeserver :)
42 +
43 +To use your home server, you have to **use a client** that communicates with your homeserver.
44 +
45 +== Clients ==
46 +
47 +[[Element>>https://element.io/]] is our client of choice. You can use it
48 +
49 +* [[on your desktop>>https://element.io/download]]
50 +* as web client:
51 +** matrix.cit.tum.de
52 +** matrix.tum.de
53 +* [[on your smartphone>>https://element.io/download]]
