 1 | # Raspberry Preserve
 2 | A Raspberry Pi based BitTorrent Sync client.
 3 | 
 4 | Once you have a clean install of a Raspberry Pi running Noobs update it by running the commands below.
 5 | 
 6 | 	sudo apt-get update
 7 | 	sudo apt-get upgrade
 8 | 
 9 | 
10 | ## Install latest Node.js
11 | 
12 | 	sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb
13 | 	sudo dpkg -i node_latest_armhf.deb
14 | 
15 | ## Install NPM
16 | 
17 | 	sudo apt-get npm
18 | 
19 | ## Create a project directory and initialize it
20 | 
21 | 	create npm package
22 | 	npm init
23 | 	touch index.js
24 | 	nano index.js
25 | 
26 | ## Add btsync repo manually and install
27 | 
28 | Follow these instruction https://melgrubb.wordpress.com/2014/08/03/raspberry-pi-home-server-part-14-bittorrent-sync/
29 | 
30 | 	sudo apt-get btsync
31 | 
32 | ## Install node packages
33 | 
34 | 	sudo npm install bittorrent-sync —-save
35 | 	sudo npm install onoff --save
36 | 
37 | ## Install Forever globally
38 | 
39 | 	sudo npm install forever -g
40 | 
41 | ## Fire up index.js with forevereverytime your boot up the pi
42 | 
43 | 	crontab -u pi -e
44 | 	@reboot /usr/bin/sudo -u pi -H /usr/local/bin/forever start /home/pi/projects/preserve/index.js
