 As always, we'll start from a [[:vms:debian|Debian template]].\\
 We'll refer to [[http://yoember.com/nodejs/the-best-way-to-install-node-js/|this article]], stating it's the best way to install Node.js !
+===== Create User =====
+We'll first create a ''dev'' user that is going to be part of the ''sudoers'' group ([[https://www.digitalocean.com/community/tutorials/how-to-create-a-sudo-user-on-ubuntu-quickstart|DigitalOcean reference]]).
+<Code>
+> adduser dev
+...
+Enter new UNIX password:
+Retype new UNIX password:
+...
+> usermod -aG sudo dev
+</Code>
 ===== Install NVM (Node Version Manager) =====
+**NOTE:** the following commands will be executed as ''dev'' user.
+==== Run the Install Script ====
 Check [[https://github.com/creationix/nvm#install-script|the NVM GitHub repo]] for the latest version of the script.
 <Code>
-> wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
+> wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.4/install.sh | bash
+=> Downloading nvm as script to '/root/.nvm'
+=> Appending nvm source string to /root/.bashrc
+=> Appending bash_completion source string to /root/.bashrc
+=> Close and reopen your terminal to start using nvm or run the following to use it now:
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
+[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
+</Code>
+In case you'd like to better grasp what the script exactly does, and what files it involves, you can refer to [[https://github.com/creationix/nvm#manual-install|https://github.com/creationix/nvm#manual-install]]
+==== Choose the Node.js Version to Install ====
+First you can **list the installed Node.js** versions:
+<Code>
+> nvm list
+nvm list
+            N/A
+node -> stable (-> N/A) (default)
+iojs -> N/A (default)
+</Code>
+Next you can **list the available Node.js versions**:
+<Code>
+> nvm ls-remote
+        v0.1.14
+        v0.1.15
+        v0.1.16
+        v0.1.17
+        ...
+        ...
+         v7.9.0
+        v7.10.0
+         v8.0.0
+         v8.1.0
+         v8.1.1
+         v8.1.2
+</Code>
+The list being very long, it is possible to reduce the output using something like: ''$ nvm ls-remote | tail -n9'' to only display the last 9 versions or ''$ nvm ls-remote | grep "v7"'' to only view version 7...
+==== Install NVM Version and Set Default ====
+<Code
+> nvm install 7.10.0
+</Code>
+When you have many Node.js versions, change the default with:
+<Code>
+> nvm use 8.0.0
+> nvm alias default 8.0.0
+</Code>
+To check the current default version:
+<Code>
+> node -v
+</Code>
+==== Upgrade NPM to the Last Version ====
+<Code>
+> npm -v
+.2.0
+> npm install -g npm
+> npm -v
+.0.3
+</Code>
+==== Increases the Amount of inotify Watches ====
+<Code>
+> echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
 </Code>
