+Thanks for contributing to `nvm`!
+
+We love pull requests, they're our favorite.
+
+However, before submitting, please review the following:
+
+ - Please include tests. Changes with tests will be merged very quickly.
+ - Please manually confirm that your changes work in `bash`, `sh`/`dash`, `ksh`, and `zsh`. Fast tests do run in these shells, but it's nice to manually verify also.
+ - Please maintain consistent whitespace - 2-space indentation, trailing newlines in all files, etc.
+ - Any time you make a change to your PR, please rebase freshly on top of master. Nobody likes merge commits.
+
+Even if you don't have all of these items covered, please still feel free to submit a PR! Someone else may be inspired and volunteer to complete it for you.
+
+Thanks again!

-# Node Version Manager
+# Node Version Manager [![Build Status](https://travis-ci.org/creationix/nvm.svg?branch=master)][3]
 
 ## Installation
 
 First you'll need to make sure your system has a c++ compiler.  For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.
 
-To install create a folder somewhere in your filesystem with the "`nvm.sh`" file inside it.  I put mine in a folder called "`.nvm`".
+### Install script
 
-Or if you have `git` installed, then just clone it:
+To install you could use the [install script][2] using cURL:
 
-    git clone git://github.com/creationix/nvm.git ~/.nvm
+    curl https://raw.githubusercontent.com/creationix/nvm/v0.17.0/install.sh | bash
 
-To activate nvm, you need to source it from your bash shell
+or Wget:
 
-    . ~/.nvm/nvm.sh
+    wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.17.0/install.sh | bash
 
-I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login.   
+<sub>The script clones the nvm repository to `~/.nvm` and adds the source line to your profile (`~/.bash_profile`, `~/.zshrc` or `~/.profile`).</sub>
+
+You can customize the install source, directory and profile using the `NVM_SOURCE`, `NVM_DIR` and `PROFILE` 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>
+
+### Manual install
+
+For manual install create a folder somewhere in your filesystem with the `nvm.sh` file inside it.  I put mine in a folder called `nvm`.
+
+Or if you have `git` installed, then just clone it, and check out the latest version:
+
+    git clone https://github.com/creationix/nvm.git ~/.nvm && cd ~/.nvm && git checkout `git describe --abbrev=0 --tags`
+
+To activate nvm, you need to source it from your shell:
+
+    source ~/.nvm/nvm.sh
+
+I always add this line to my `~/.bashrc`, `~/.profile`, or `~/.zshrc` file to have it automatically sourced upon login.
 Often I also put in a line to use a specific version of node.
-    
+
 ## Usage
 
-To download, compile, and install the v0.4.1 release of node, do this:
+You can create an `.nvmrc` file containing version number in the project root directory (or any parent directory).
+`nvm use`, `nvm install`, `nvm exec`, and `nvm run` will all respect an `.nvmrc` file.
 
-    nvm install v0.4.1
+To download, compile, and install the latest v0.10.x release of node, do this:
+
+    nvm install 0.10
 
 And then in any new shell just use the installed version:
 
-    nvm use v0.4.1
+    nvm use 0.10
 
-If you want to see what versions are available:
+Or you can just run it:
+
+    nvm run 0.10 --version
+
+Or, you can run any arbitrary command in a subshell with the desired version of node:
+
+    nvm exec 0.10 node --version
+
+If you want to see what versions are installed:
 
     nvm ls
 
+If you want to see what versions are available to install:
+
+    nvm ls-remote
+
 To restore your PATH, you can deactivate it.
 
     nvm deactivate
 
 To set a default Node version to be used in any new shell, use the alias 'default':
 
-    nvm alias default v0.4.1
+    nvm alias default 0.10
+
+To use a mirror of the node binaries, set `$NVM_NODEJS_ORG_MIRROR`:
+
+    export NVM_NODEJS_ORG_MIRROR=http://nodejs.org/dist
+    nvm install 0.10
+
+    NVM_NODEJS_ORG_MIRROR=http://nodejs.org/dist nvm install 0.10
+
+`nvm use` will, by defaut, create a "current" symlink. Set `$NVM_SYMLINK_CURRENT` to any value other than "true" to disable this behavior.

+
+## Running tests
+Tests are written in [Urchin]. Install Urchin (and other dependencies) like so:
+
+    npm install
+
+There are slow tests and fast tests. The slow tests do things like install node
+and check that the right versions are used. The fast tests fake this to test
+things like aliases and uninstalling. From the root of the nvm git repository,
+run the fast tests like this.
+
+    npm run test/fast
+
+Run the slow tests like this.
+
+    npm run test/slow
+
+Run all of the tests like this
+
+    npm test
+
+Nota bene: Avoid running nvm while the tests are running.
+
+## Bash completion
+
+To activate, you need to source `bash_completion`:
+
+  	[[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
+
+Put the above sourcing line just below the sourcing line for NVM in your profile (`.bashrc`, `.bash_profile`).
+
+### Usage
+
+nvm
+
+	$ nvm [tab][tab]
+	alias          copy-packages  help           list           run            uninstall      version
+	clear-cache    deactivate     install        ls             unalias        use
+
+nvm alias
+
+	$ nvm alias [tab][tab]
+	default
+
+	$ nvm alias my_alias [tab][tab]
+	v0.6.21        v0.8.26       v0.10.28
+
+nvm use
+
+	$ nvm use [tab][tab]
+	my_alias        default        v0.6.21        v0.8.26       v0.10.28
+
+nvm uninstall
+
+	$ nvm uninstall [tab][tab]
+	my_alias        default        v0.6.21        v0.8.26       v0.10.28
+
+## Problems
+
+If you try to install a node version and the installation fails, be sure to delete the node downloads from src (~/.nvm/src/) or you might get an error when trying to reinstall them again or you might get an error like the following:
+
+    curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.
+
+Where's my 'sudo node'? Checkout this link:
+
+https://github.com/creationix/nvm/issues/43
+
+on Arch Linux and other systems using python3 by default, before running *install* you need to
+
+      export PYTHON=python2
+
+After the v0.8.6 release of node, nvm tries to install from binary packages. But in some systems, the official binary packages don't work due to incompatibility of shared libs. In such cases, use `-s` option to force install from source:
+
+    nvm install -s 0.8.6
