+Matrix synapse service with IRC and Telegram gateways
+=====================================================
+
+A collection of systemd services that run synapse, matrix-appservice-irc
+and mautrix-telegram in a read-only alpine squashfs image.
+
+Building the squashfs image
+---------------------------
+
+Run:
+
+``` {.sourceCode .shell}
+$ sh build.sh
+```
+
+It will create a rootfs/ folder with an alpine filesystem, install
+synapse, matrix-appservice-irc and mautrix-telegram and compress it into
+a squashfs image that will be used as a root filesystem for the
+container.
+
+If the script finished successfully, you should get an \~50M matrix.raw
+image.
+
+Running the portable services
+-----------------------------
+
+Attach the container with `sudo portablectl attach ./matrix.raw`.
+
+The output should look something like this:
+
+``` {.sourceCode .shell}
+$ sudo portablectl attach ./matrix.raw
+
+Created directory /etc/systemd/system.attached.
+Created directory /etc/systemd/system.attached/matrix.service.d.
+Written /etc/systemd/system.attached/matrix.service.d/20-portable.conf.
+Created symlink /etc/systemd/system.attached/matrix.service.d/10-profile.conf → /usr/lib/systemd/portable/profile/default/service.conf.
+Copied /etc/systemd/system.attached/matrix.service.
+Created directory /etc/systemd/system.attached/matrix-telegram.service.d.
+Written /etc/systemd/system.attached/matrix-telegram.service.d/20-portable.conf.
+Created symlink /etc/systemd/system.attached/matrix-telegram.service.d/10-profile.conf → /usr/lib/systemd/portable/profile/default/service.conf.
+Copied /etc/systemd/system.attached/matrix-telegram.service.
+Created directory /etc/systemd/system.attached/matrix-appservice-irc.service.d.
+Written /etc/systemd/system.attached/matrix-appservice-irc.service.d/20-portable.conf.
+Created symlink /etc/systemd/system.attached/matrix-appservice-irc.service.d/10-profile.conf → /usr/lib/systemd/portable/profile/default/service.conf.
+Copied /etc/systemd/system.attached/matrix-appservice-irc.service.
+Created symlink /etc/portables/matrix.raw → /home/vladan/dev/portabled/alpine-matrix/matrix.raw.
+```
+
+Start/Stop as any other systemd service, e.g:
+
+``` {.sourceCode .shell}
+sudo systemctl start matrix-appservice-irc.service matrix-telegram.service
+sudo systemctl stop matrix.service
+```
+
+Existing matrix installations
+-----------------------------
+
+1.  Stop your current services.
+2.  Copy all configuration files to `/etc/matrix`.
+3.  Run all portable services, so that they create all directories in
+    `/var/lib`.
+4.  Copy all data files, e.g. homeserver.db if you\'re using sqlite,
+    media and upload folders for synapse, rooms.db for the irc gateway,
+    etc. to `/var/lib/matrix-{synapse,telegram,appservice-irc}`.
+
+Warning
+-------
+
+You\'ll need to modify the configuration if the services are configured
+to log to disk, i.e. modify any filesystem except
+`/var/lib/matrix-{synapse,telegram,appservice-irc}`.
+
+TODO
+----
+
+-   Use a Makefile to build the image. Add attach, detach and clean
+    targets.
+-   Rename matrix.service to matrix-synapse.service and add
+    matrix.target that starts matrix.service
