-#Beaglebone Black
-As the BeagleBoneBlack already has node.js baked into it's default Angstrom OS then some of these tips are optional...
-
-##Updating node.js and bonescript to latest version (optional)
-
-ssh into the BBB as root, and at the prompt
-
-    opkg update
-    opkg install screen nodejs bonescript
-
-This also installs screen which we use as the preferred way to be able to keep an eye on the Node-RED console.
-
-##Installation
-
-As per other distributions.
-
-Edit the node-red/settings.js file to contain
-
-    //functionGlobalContext: { }
-    functionGlobalContext: { bonescript:require('bonescript') }
-
-This makes the entire bonescript library available to any functions you write. They are accessible by declaring in a function (for example) :
-
-    var b = context.global.bonescript;
-
-Then manually start Node-RED,
-
-    cd node-red
-    node red.js
-
-then assuming you haven't changed the beaglebone's hostname use a connected browser to browse http://beaglebone.local:1880
-
-##Blink
-
-To run a "blink" flow that uses the USR3 and USR2 LEDs import the following flow, by cutting the line below into your clipboard.

-
-Then in the Node-RED browser - Use Options (top right) - Import From - Clipboard, or the shortcut Ctrl-I, and paste in the text, Ctrl-V.
-
-Hit <b>Deploy</b> - and the flow should start running. USR3 LED should start toggling on and off once a second. USR2 LED can be set on or off depending on which button is clicked.
-
-##Making Node-RED autostart on boot (optional)
-
-As Angstrom uses the Upstart way of doing things we need to create a couple of files.
-
-One in **/lib/systemd/system**
-called **node-red.service**
-containing
-
-    [Unit]
-    Description=Start Node-RED
-
-    [Service]
-    Environment=HOME=/home/root
-    WorkingDirectory=/home/root
-    ExecStart=/home/root/go.sh
-    SyslogIdentifier=Node-RED
-    RemainAfterExit=yes
-
-    [Install]
-    WantedBy=multi-user.target
-
-and one in **/home/root**
-called **go.sh**
-containing
-
-    #!/bin/bash -
-    ntpdate pool.ntp.org
-    export NODE_PATH=/usr/lib/node_modules
-    cd /home/root/node-red/
-    /usr/bin/screen -dmS red /usr/bin/node red.js
-
-then run the following commands
-
-    systemctl enable node-red.service
-    systemctl start node-red.service
-
-You should then be able to type
-
-    screen -ls
-and see red listed.
-To get to the terminal type
-
-    screen -r red
-type Ctrl-A-D to detach and leave it running
-
-Notice that go.sh also tries to set the clock correctly using ntpdate. You shouldn't have to do this but I find the BBB does sometimes take an age to sync up - so forcing it helps.
