## Intro
`nvm` allows you to quickly install and use different versions of node via the command line.
**Example:**
 [code] 
Simple as that!
## About
nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. `nvm` works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and Windows WSL.
## Installing and Updating
### Install & Update Script
To **install** or **update** nvm, you should run the [install script][2]. To do that, you may either download and run the script manually, or use the following cURL or Wget command:

 [code] 
Running either of the above commands downloads a script and runs it. The script clones the nvm repository to `~/.nvm`, and attempts to add the source lines from the snippet below to the correct profile file (`~/.bashrc`, `~/.bash_profile`, `~/.zshrc`, or `~/.profile`). If you find the install script is updating the wrong profile file, set the `$PROFILE` env var to the profile file’s path, and then rerun the installation script.
 [code] 
#### Additional Notes
- If the environment variable `$XDG_CONFIG_HOME` is present, it will place the `nvm` files there.
- You can add `--no-use` to the end of the above script to postpone using `nvm` until you manually `use` it:
 [code] 
- 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="path/to/nvm"`. Ensure that the `NVM_DIR` does not contain a trailing slash.
- The installer can use `git`, `curl`, or `
