4 +== What is Matrix? ==
4 4  
5 5  
6 -There are two Matrix-Servers:
7 - 1 matrix.tum.de (LRZ-ID)
8 - 1 matrix.cit.tum.de (ITO-ID)
7 +[[Matrix>>https://matrix.org/]] is a chat system very similar to E-Mail, but instantaneous and secure.
9 9  
10 -You can log in any of them with the appropriate ID and password.
11 -The Matrix Server is available as web but also as client. It can be found as web interface under the following links:
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 +)))
12 12  
13 -[[matrix.cit.tum.de (ITO- ID)>>url:https://matrix.cit.tum.de/#/welcome]]
19 +So People have their **account on one server** but can write messages **to anyone on other servers**.
20 +
14 14  
15 -[[matrix.tum.de (LRZ-TUM-ID)>>url:https://matrix.tum.de/#/welcome]]
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.
16 16  
26 +== Home Server ==
17 17  
18 -[[ Here>>url:https://element.io/get-started]] you can find installation for IOS, Android, Mac, Linux and Windows.
28 +Messages are stored and synced between home servers.
19 19  
20 -[[image:elementdriver.png||width="1000"]]
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:
21 21  
32 +* **matrix.cit.tum.de** for CIT accounts: @username:cit.tum.de
33 +* **matrix.tum.de** for TUM accounts: @username:tum.de
22 22  
23 -== Log in ==
35 +You only need to use one account and can communicate with any other homeserver of the world.
24 24  
37 +If you don't have a CIT or TUM account, you can use a public homeserver instead:
25 25  
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 :)
26 26  
27 -=== Log in to the web interface with TUM login data ===
43 +To use your home server, you have to **use a client** that communicates with your homeserver.
28 28  
45 +== Clients ==
29 29  
47 +[[Element>>https://element.io/]] is our client of choice. You can use it
