How to install Syncthing on Raspberry Pi + start on boot [semi-automatic]

##Run install_syncthing.sh

$ curl -s https://gist.githubusercontent.com/hdml/7b079c114d3e20bf69f1/raw/1cd3647b1db4f80726c145fba725e27993a7fcdb/install_syncthing.sh | sudo bash

Start syncthing

$ syncthing

Wait until you get something like:

INFO: Device 7NNIJMJ-RQ657WA-RI5YH6L-RQ657WA-RQ657WA-VGKSUYP-U6QBJNA-RQ657WA
write down this number or copy it if you SSH'd to your pi.

quit the operation using CTRL + C.

Change the config file so you can access the GUI from any PC within the network

$ nano ~/.config/syncthing/config.xml

Change 127.0.0.1 to 0.0.0.0

<gui enabled="true" tls="false">
    <address>127.0.0.1:8384</address>
</gui>

OPTIONAL: if you forward port 8384 (or any port you would like to use) on your router to you pi, you can access the GUI from anywhere in the world as long as you know you home(public) IP address. Make sure you use https and enable authentication!

Start the syncthing service

$ sudo service syncthing start

on a PC in the same network, go to the GUI and disable automatic updates. GUI -> Settings -> Disable Automatic updates hit save and restart syncthing.

If there's a new version of syncthing, use

$ sudo syncthing -upgrade

Then reboot the system.

$ sudo reboot

To remove syncthing use

$ sudo rm -r /opt/syncthing
$ sudo rm /usr/bin/syncthing
$ sudo rm -r /home/pi/.config/syncthing
$ sudo rm /etc/init.d/syncthing

optionally, delete any folder used with syncthing.

How can I keep Syncthing up to date?
When I type sudo syncthing -upgrade
I get:
INFO: Default folder created and/or linked to new config
FATAL: Upgrade: upgrade unsupported
