8 -== What is matrix? ==
9 9  
10 +[[Matrix>>https://matrix.org/]] is a chat system very similar to E-Mail, but instantaneous and secure.
10 10  
11 -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.
12 +* You need to register an account at a provider (e.g. tum.de, or lmu.de)
13 +* Whatever your provider is, you can talk to people using other providers
14 +** (((
15 +For example {{code language="none"}}@someprofessor:tum.de{{/code}} can communicate with {{code language="none"}}@someresearcher:lmu.de{{/code}}!
16 +)))
17 +* (((
18 +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!
19 +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.
20 +)))
12 12  
13 -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.
22 +So People have their **account on one server** but can write messages **to anyone on other servers**.
23 +
14 14  
25 +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, ...).
26 +All your messages are **synced** between all your devices - web clients, desktop clients, smartphone apps.
27 +For additional security, encryption keys of contacts can be verified and then stored as trusted.
15 15  
29 +== Home Server ==
16 16  
17 -Download and sign in to the desktop version of Matrix chat
31 +Messages are stored and synced between home servers.
18 18  
33 +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:
19 19  
35 +* **matrix.cit.tum.de** for CIT accounts: @username:cit.tum.de
36 +* **matrix.tum.de** for TUM accounts: @username:tum.de
20 20  
21 -[[ Here>>url:https://element.io/get-started]] you can find installation for IOS, Android, Mac, Linux and Windows.
38 +You only need to use one account and can communicate with any other homeserver of the world.
22 22  
40 +If you don't have a CIT or TUM account, you can use a public homeserver instead:
23 23  
42 +* matrix.org: [[https:~~/~~/app.element.io/#/register>>https://app.element.io/#/register]]
43 +* or any other homeserver [[https:~~/~~/joinmatrix.org/servers/>>https://joinmatrix.org/servers/]]
44 +* or, host your own homeserver :)
24 24  
25 -== Sign in ==
46 +To use your home server, you have to **use a client** that communicates with your homeserver.
26 26  
27 -You can sign in to the desktop version or web interface.
48 +== Clients ==
28 28  
29 -=== Sign in to the desktop version ===
50 +[[Element>>https://element.io/]] is our client of choice.

52 +* [[Desktop Client>>https://element.io/download]] (easily provided in [[your Linux distribution of choice>>https://repology.org/project/element-desktop]])
