 Rather than dropping support for NodeJS v4 (and hence for the system NodeJS version of Ubuntu), we use ws v1 as a dependency in `package.json`, but allow any version of ws to be used.
 
+#### Usage on Ubuntu
+
+As mentioned above, Ubuntu 16.04 ships with Node 4.2, which only works with ws v1. To use that, do the following:
+
+```console
+sudo npm install -g ws@1 autobahn
+export NODE_PATH=/usr/local/lib/node_modules/
+```
+
+> This first install ws at version 1, and then installs Autobahn. When you install Autobahn without installing ws first, the latest ws version will be installed as a dependency of Autobahn, hence ws v2, and that won't work.
+
+To use a current Node with ws v2, do the following:
+
+```console
+cd ~
+wget https://nodejs.org/dist/v6.10.1/node-v6.10.1-linux-x64.tar.xz
+tar xvf node-v6.10.1-linux-x64.tar.xz
+export PATH=${HOME}/node-v6.10.1-linux-x64/bin:${PATH}
+export NODE_PATH=${HOME}/node-v6.10.1-linux-x64/lib/node_modules
+```
+
+This should give you:
+
+```console
+oberstet@office-corei7:~$ which node
+/home/oberstet/node-v6.10.1-linux-x64/bin/node
+oberstet@office-corei7:~$ which npm
+/home/oberstet/node-v6.10.1-linux-x64/bin/npm
+oberstet@office-corei7:~$ node -v
+v6.10.1
+oberstet@office-corei7:~$ npm -v
+3.10.10
+```
+
+Now you can install Autobahn:
+
+```console
+npm install -g autobahn
+```
+
+and check
+
+```console
+oberstet@office-corei7:~$ node -e "var autobahn = require('autobahn'); console.log(autobahn.version);"
+0.12.0
+```
+
