 ## 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:
+### Install NVM on macOS
+Change the ownership of these directories to your user
 ```sh
-curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
+sudo chown -R $(whoami) /usr/local/share/zsh /usr/local/share/zsh/site-functions
 ```
+
+Make sure that user has write permission
 ```sh
-wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
+chmod u+w /usr/local/share/zsh /usr/local/share/zsh/site-functions
+```
+
+Use Humebrew to install NVM
+```sh
+brew install nvm
+```
+
+Create a director for NVM in home
+```sh
+mkdir ~/.nvm
+```
+
+Configure Required Environment Variable
+```sh
+vim ~/.bash_profile
+```
+
+Add the following lines to ~/.bash_profile
+```sh
+export NVM_DIR=~/.nvm
+source $(brew --prefix nvm)/nvm.sh
+```
+Press ESC +:wq to save and close the file.
+
+Load the variable to the current shell environment
+```sh
+source ~/.bash_profile
 ```
 
 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 (`~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`).

-```sh
-export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
-[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
-```

 #### Additional Notes
 
 - If the environment variable `$XDG_CONFIG_HOME` is present, it will place the `nvm` files there.</sub>
