 ## Installation
 
+### Install script
+
+To install or update nvm, you can use the [install script][2] using cURL:
+
+```sh
+curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash
+```
+
+or Wget:
+
+```sh
+wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.6/install.sh | bash
+```
+
+<sub>The script clones the nvm repository to `~/.nvm` and adds the source line to your profile (`~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`).</sub>
+
+```sh
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
+```
+
+You can customize the install source, directory, profile, and version using the `NVM_SOURCE`, `NVM_DIR`, `PROFILE`, and `NODE_VERSION` variables.
+Eg: `curl ... | NVM_DIR=/usr/local/nvm bash` for a global install.
+
+<sub>*NB. The installer can use `git`, `curl`, or `wget` to download `nvm`, whatever is available.*</sub>
+
+**Note:** On Linux, after running the install script, if you get `nvm: command not found` or see no feedback from your terminal after you type:
+
+```sh
+command -v nvm
+```
+simply close your current terminal, open a new terminal, and try verifying again.
+
+**Note:** On OS X, if you get `nvm: command not found` after running the install script, one of the following might be the reason:-
+ - your system may not have a [`.bash_profile file`] where the command is set up. Simply create one with `touch ~/.bash_profile` and run the install script again
+ - you might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry.
+
+If the above doesn't fix the problem, open your `.bash_profile` and add the following line of code:
+
+`source ~/.bashrc`
+

+### Verify installation
+
+To verify that nvm has been installed, do:
+
+```sh
+command -v nvm
+```
+
+which should output 'nvm' if the installation was successful. Please note that `which nvm` will not work, since `nvm` is a sourced shell function, not an executable binary.
+
+### Important Notes
+
 If you're running a system without prepackaged binary available, which means you're going to install nodejs or io.js from its source code, you need to make sure your system has a C++ compiler. For OS X, Xcode will work, for Debian/Ubuntu based GNU/Linux, the `build-essential` and `libssl-dev` packages work.

 **Note:** Git versions before v1.7 may face a problem of cloning nvm source from GitHub via https protocol, and there is also different behavior of git before v1.6, so the minimum required git version is v1.7.0 and we recommend v1.7.9.5 as it's the default version of the widely used Ubuntu 12.04 LTS. If you are interested in the problem we mentioned here, please refer to GitHub's [HTTPS cloning errors](https://help.github.com/articles/https-cloning-errors/) article.

 The Node project has some desire but no concrete plans (due to the overheads of building, testing and support) to offer Alpine-compatible binaries.
 
 As a potential alternative, @mhart (a Node contributor) has some [Docker images for Alpine Linux with Node and optionally, npm, pre-installed](https://github.com/mhart/alpine-node).
 
+## Docker for development environment
+
+To make the development and testing work easier, we have a Dockerfile for development usage, which is based on Ubuntu 14.04 base image, prepared with essential and useful tools for `nvm` development, to build the docker image of the environment, run the docker command at the root of `nvm` repository:
+
+```sh
+$ docker build -t nvm-dev .
+```
+
+This will package your current nvm repository with our pre-defiend development environment into a docker image named `nvm-dev`, once it's built with success, validate your image via `docker images`:
+
+```sh
+$ docker images
+
+REPOSITORY         TAG                 IMAGE ID            CREATED             SIZE
+nvm-dev            latest              9ca4c57a97d8        7 days ago          1.22 GB
+```
+
+If you got no error message, now you can easily involve in:
+
+```sh
+$ docker run -it nvm-dev -h nvm-dev
+
+nvm@nvm-dev:~/.nvm$
+```
+
+Please note that it'll take about 15 minutes to build the image and the image size would be about 1.2GB, so it's not suitable for production usage.
