Correction of errors in the documentation:

1) Rooms are not private because anyone who has an account on the
Matrix network can access it
2) The issue concerning  the phone number is (maybe) not a bug but
the effect of a service limitation (however undocumented)
3) Added a clearer mention about the existence of a mobile app version of Riot
(quite correct for that matter) and adding the link for
download applications.
4) Clarification on the convention for naming default room of
each community

 ## Introduction
 
 **Matrix** is now used for Virtual Assembly discussions, replacing Slack. A Matrix server is self-hosted on the association server, and responds to the domain name **matrix.virtual-assembly.org**.
 
-The principle of Matrix is a juxtaposition of "rooms", spread over a *federation of servers*, which are all independent of each other (and not hierarchical). These rooms can be grouped into **communities**<sup>1</sup> (*groups*) which are divided into filters across all Matrix federation. A room can belong to several communities. Each community has at least one room with the same name.
+The principle of Matrix is a juxtaposition of "rooms", spread over a *federation of servers*, which are all independent of each other (and not hierarchical). These rooms can be grouped into **communities**[^1] (*groups*) which are divided into filters across all Matrix federation. A room can belong to several communities. Each community has at least one room. Our convention is to give the community's name to this default room.
 
 For example, there is a **General** community, which currently includes two rooms: *General* and *Reception*.
 
 ## Accessing rooms — Tools

+However, having an account on the ** matrix.virtual-assembmly.org ** server will give you more comfort in the use of the lounges, and in the first place will improve the functions of navigation, search and discovery.
 
-The instance of the Virtual Assembly is not public. You have to be granted by the sysadmin team of the Assembly, so check tha point first: If you were on Slack, or have been in contact with the Assembly for a long time, it is likely that this is the case. Otherwise, contact someone you know in the Assembly, so that this person alerts the sysadmin team to allow access to the Virtual Assembly rooms<sup>3</sup>. You will soon be notified to create an account.

 Depending on which page you are on, you can see two different messages. The difference between "**Join the community**" and "**Join the room**" is that, in the first case, you will see the community icon in the far left sidebar of the window. You can be part of as many communities as you want and these ones will visually separate the rooms following different domains of interest.
