install nodejs 5.x on debian wheezy

[bast...@gmail.com]

Hi,

I need to install nodejs (5.x) on my server based on debian wheezy (7.4).

From this guide (https://github.com/nodesource/distributions#debinstall) 

# Using Debian, as root
curl -sL https://deb.nodesource.com/setup_5.x | bash -
apt-get install -y nodejs

but there's a link to this page https://github.com/nodesource/distributions/blob/master/OLDER_DISTROS.md with some other script instructions.

I don't understand if are they just additional information and more detail on how installation works, or have I to do something?

Just run the following codes, is it enough?

# Using Debian, as root
curl -sL https://deb.nodesource.com/setup_5.x | bash -
apt-get install -y nodejs

Thanks a lot
