steps.md

Assumes a fresh install of Ubuntu 12.04 LTS.

1. Setup the system to handle compiling and installing from source.

    $ sudo apt-get install build-essential
   

2. If SSL support is needed then we will need to install libssl-dev.

    $ sudo apt-get install libssl-dev
   

3. The install script uses curl, so we will need to install curl.

    $ sudo apt-get install curl
   

4. Change into the directory containing the install script and source it.

    $ . node-and-npm-in-30s.sh
   

   N.B. This step takes a while.

5. Finally, check that the latest version of node and npm are indeed installed.

    $ node -v
    $ npm -v
