-Homebrew installation is not supported.
+Homebrew installation is not supported. If you have issues with homebrew-installed `nvm`, please `brew uninstall` it, and install it using the instructions below, before filing an issue.
+
+Note: If you're using `zsh` you can easily install `nvm` as a zsh plugin. Install [`zsh-nvm`](https://github.com/lukechilds/zsh-nvm) and run `nvm_update` to update.
 
 ### Install script
 
 To install or update nvm, you can use the [install script][2] using cURL:
 
-    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.2/install.sh | bash
+```sh
+curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/install.sh | bash
+```
 
 or Wget:
 
-    wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.2/install.sh | bash
+```sh
+wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.3/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>
 
-You can customize the install source, directory and profile using the `NVM_SOURCE`, `NVM_DIR`, and `PROFILE` variables.
-Eg: `curl ... | NVM_DIR="path/to/nvm" bash`
+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 OS X, if you get `nvm: command not found` after running the install script, 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.
 
+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.

 To activate nvm, you need to source it from your shell:

 export NVM_DIR="$HOME/.nvm"

+```sh
 cd "$NVM_DIR" && git fetch origin && git checkout `git describe --abbrev=0 --tags`

 After upgrading, don't forget to activate the new version:

+To download, compile, and install the latest release of node, do this:
 
-    nvm install 5.0
+```sh

 And then in any new shell just use the installed version:
 
-    nvm use 5.0
+```sh
+nvm use node
+```
 
 Or you can just run it:
 
-    nvm run 5.0 --version
-
+```sh
+nvm run node --version
+```
 Or, you can run any arbitrary command in a subshell with the desired version of node:
 
+```sh
 nvm exec 4.2 node --version
+```
 
 You can also get the path to the executable to where it was installed:
 
+```sh
 nvm which 5.0
+```

  - `stable`: this alias is deprecated, and only truly applies to `node` `v0.12` and earlier. Currently, this is an alias for `node`.
  - `unstable`: this alias points to `node` `v0.11` - the last "unstable" node release, since post-1.0, all node versions are stable. (in semver, versions communicate breakage, not stability).
 
+### Long-term support
+Node has a [schedule](https://github.com/nodejs/LTS#lts_schedule) for long-term support (LTS) You can reference LTS versions in aliases and `.nvmrc` files with the notation `lts/*` for the latest LTS, and `lts/argon` for LTS releases from the "argon" line, for example. In addition, the following commands support LTS arguments:
+ - `nvm install --lts` / `nvm install --lts=argon`
+ - `nvm uninstall --lts` / `nvm uninstall --lts=argon`
+ - `nvm use --lts` / `nvm use --lts=argon`
+ - `nvm exec --lts` / `nvm exec --lts=argon`
+ - `nvm run --lts` / `nvm run --lts=argon`
+ - `nvm ls-remote --lts` / `nvm ls-remote --lts=argon`
+ - `nvm version-remote --lts` / `nvm version-remote --lts=argon`
+
+Any time your local copy of `nvm` connects to https://nodejs.org, it will re-create the appropriate local aliases for all available LTS lines. These aliases (stored under `$NVM_DIR/alias/lts`), are managed by `nvm`, and you should not modify, remove, or create these files - expect your changes to be undone, and expect meddling with these files to cause bugs that will likely not be supported.
+
+### Migrating global packages while installing
 If you want to install a new version of Node.js and migrate npm packages from a previous version:
 
+```sh
 nvm install node --reinstall-packages-from=node
+```
 
 This will first use "nvm version node" to identify the current version you're migrating packages from. Then it resolves the new version to install from the remote server and installs it. Lastly, it runs "nvm reinstall-packages" to reinstall the npm packages from your prior version of Node to the new one.
 
 You can also install and migrate npm packages from specific versions of Node like this:
 
-    nvm install v5.0 --reinstall-packages-from=4.2
+```sh
+nvm install 6 --reinstall-packages-from=5
 nvm install v4.2 --reinstall-packages-from=iojs
+```
 
+### io.js
 If you want to install [io.js](https://github.com/iojs/io.js/):
 
+```sh
 nvm install iojs
+```
 
 If you want to install a new version of io.js and migrate npm packages from a previous version:
 
+```sh
 nvm install iojs --reinstall-packages-from=iojs
+```
 
 The same guidelines mentioned for migrating npm packages in Node.js are applicable to io.js.
 
+### System version of node
 If you want to use the system-installed version of node, you can use the special default alias "system":
 
+```sh
 nvm use system
 nvm run system --version
+```
 
+### Listing versions
 If you want to see what versions are installed:
 
+```sh
 nvm ls
+```
 
 If you want to see what versions are available to install:
 
+```sh
 nvm ls-remote
+```
 
 To restore your PATH, you can deactivate it:
 
+```sh
 nvm deactivate
+```
 
 To set a default Node version to be used in any new shell, use the alias 'default':
 
+```sh
 nvm alias default node
+```
 
 To use a mirror of the node binaries, set `$NVM_NODEJS_ORG_MIRROR`:
 
+```sh
 export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist
 nvm install node
 
 NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 4.2
+```
