> *This package allows you to install Mautrix-Signal quickly and simply on a YunoHost server.
If you don't have YunoHost, please consult [the guide](https://yunohost.org/#/install) to learn how to install it.*
## Overview
A puppeting bridge between Matrix and Signal packaged as a YunoHost service. Messages, notifications (and sometimes media) are bridged between a Signal user and a Matrix user. Currently the Matrix user can NOT invite other Matrix user in a bridged Signal room, so only someone with a Signal account can participate to Signal group conversations. The ["Mautrix-Signal"](https://docs.mau.fi/bridges/python/signal/index.html) bridge consists in a Synapse App Service and relies on postgresql (mysql also possible). Therefore, [Synapse for YunoHost](https://github.com/YunoHost-Apps/synapse_ynh) should be installed beforehand.
**Shipped version:** 0.1.0
## Screenshots
## List of known public services
* Ask on one of the following rooms: #mautrix_yunohost:matrix.fdn.fr or #signal:maunium.net
## Bridging usage
** Note that several Signal and Matrix users can be bridged, each Signal account has its own bot administration room. If they are in a same Signal group, only one matrix room will be created. **
### Bridge a Signal user and a Matrix user
* First your Matrix user or Synapse Server has to be authorized in the Configuration of the bridge (see below)
* Then, invite the bot (default @signalbot:yoursynapse.domain) in this new Mautrix-Signal bot administration room.
* If the Bot does bot accept, see the [troubleshooting page](https://docs.mau.fi/bridges/general/troubleshooting.html)
* Send ``!sg help`` to the bot in the created room to know how to control the bot.
See also [upstream wiki Authentication page](https://docs.mau.fi/bridges/python/signal/authentication.html)
#### Linking the Bridge as a secondary device
* Type ``!sg link``
* Open Signal App of your primary device
* Open Settings => Linked Devices => Capture the QR code with the camera
* By defaults, only conversations with very recent messages will be bridged
* Accept invitations to the bridged chat rooms
#### Registering the Bridge as a primary device
* Type ``!sg register <phone>``, where ``<phone>`` is your phone number in the internation format with no space, e.g. ``!sg register +33612345678``
* Answer in the bot room with the verification code that you reveived in SMS.
* Set a profile name with ``!sg set-profile-name <name>``
### Double puppeting
* Log in with ``login-matrix <accesstoken>``
* After logging in, the default Matrix puppet of your Signal account should leave rooms and your account should join all rooms the puppet was in automatically.
### Relaybot: Bridge a group for several Matrix and several Signal users to chat together

## Configuration of the bridge
The bridge is [roughly configured at installation](https://github.com/YunoHost-Apps/mautrix_signal_ynh/blob/master/conf/config.yaml), e.g. allowed admin and user of the bot. Finer configuration can be done by modifying the
following configuration file with SSH:
```/opt/yunohost/mautrix_signal/config.yaml```
and then restarting the mautrix_signal service.
## Documentation
* Official "Mautrix-Signal" documentation: https://docs.mau.fi/bridges/python/signal/index.html
* Matrix room (Matrix Bridges in Yunohost): #mautrix_yunohost:matrix.fdn.fr
* Matrix room (upstream app): #signal:maunium.net
In case you need to upload your logs somewhere, be aware that they contain your contacts' and your phone numbers. Strip them out with
``| sed -r 's/[0-9]{10,}/📞/g' ``
* "Mautrix-Signal" bridge is based on the [signal daemon](https://gitlab.com/signald/signald) project.
* YunoHost documentation: If more specific documentation is needed, feel free to contribute.
## YunoHost specific features
#### Multi-user support
* Bot users are not related to Yunohost users. Any Matrix account or Synapse server autorized in the configuration of the bridge can invite/use the bot.
* The Signal bot is a local Matrix-Synapse user, but accessible through federation (synapse public or private).
* Several Signal and Matrix users can be bridged with one bridge, each user has its own bot administration room.
* If several bot users are in a same Signal group, only one Matrix room will be created by the bridge.
* See https://github.com/YunoHost-Apps/synapse_ynh#multi-users-support
#### Multi-instance support
* Multi-instance installation should work. Several bridge instances could be installed for one Matrix-Synapse instance so that one Matrix user can bridge several Signal accounts.
* Several bridge instances could be installed for each Matrix-Synapse instance to benefit from it. But one bridge can be used by users from several Matrix-Synapse instances.
