+# Backup Your Terminal/Shell Environment
+
+This section will talk about how to update the Terminal's look and feel, as well as how to edit files using the command line editor, `nano`
+
+At the end of this guide, we will add some color to your command line, and your command line will be formatted for development.
+
+## Backing up files
+
+The first thing we'll do is backup your existing terminal setup.
+
+There are a lot of ways that your terminal can be set up determined by different configuration files.
+
+We want to remove the old ways so we can start with a clean slate.
+
+Make back ups of the files listed below. You may get a `No such file or directory` error for some of them. That's ok.
+
+- `mv ~/.bashrc .bashrc.bak`
+- `mv ~/.bash_profile .bash_profile.bak`
+- `mv ~/.profile .profile.bak`
+- `mv ~/.zshrc .zshrc.bak`
+
+## Install Z Shell
+
+```bash
+sudo apt-get install zsh
+```
+
+After installing, type `zsh`. Zsh will ask you to choose some configuration. We will do this later by installing `oh-my-zsh`.  Chose option 0 to create the config file (prevent this message to show again).
+
+Now, let's move on to getting our development applications installed.

+# Install VSCode Text Editor
+
+Now it's time to install VSCode Text Editor, a sophisticated text editor for code, markup, and prose.
+
+> **Follow the below instructions in order**, paying attention to any notes specific to Windows or Mac, depending on your operating system.
+
+## Get Started
+
+- Close any open terminal windows.
+- Download [VSCode](https://code.visualstudio.com/download) and install.
+- If this window displays during set up, be sure the following boxes are selected
+![VSCode](../vscode.png)
+
+### Install Additional VSCode Extensions
+
+We'll now be adding some functionality to your new code editor by installing a number of extensions.
+
+- You can open VSCode through your terminal using `code .`
+- On the bottom left hand side you will see a settings ("gear") icon.
+- Click this, then click "Extensions".
+- A side-bar will slide out and at the top you can search for the listed extensions below, and click the green 'Install' button for each:
+  - liveserver
+  - ESLint
+  - markdownlint
+  - editorconfig
+  - HTML Preview
+  - Thunder Client
+
+There are many other extensions to choose from that will make your coding life a lot easier. Your instructors, TAs and classmates will all be great resources as to what works well for them.
+
+[VSCode's documentation](https://code.visualstudio.com/docs) is excellent. Review it now to familiarize yourself with the basics.

+# Verify Your Setup Part 1
+
+> By the time you’ve completed the guide, you should be able to run the following commands in your terminal and see the expected output. Your versions may be slightly different than what is listed here due to recent updates.
+
+- `code --version`
+  - `1.64.2`
+- `git --version`
+  - `git version 2.34.1`
+- `node --version`
+  - `v17.31.1`
+- `npm --version`

+- `eslint --version`
+  - `v8.1.0`
+- `tree --version`
+  - `tree v2.0.1 (c) 1996 - 2018 ...`
+- `git config --list` should contain at least the following:
+  - `user.name=YOUR NAME`
+  - `user.email=YOUR EMAIL`
+  - `core.editor=code --wait`
+  - `init.defaultbranch=main`
+  - Type the letter `q` to exit the config screen and return to the previous screen.
+- `code .`
+  - should open VS Code with your current folder contents
+
+## Verify Your Setup Part 2
+
+Run the following command
+
+```bash
+curl -Ls https://bit.ly/3qMWhbE | bash
+```
+
+You should get a successful message. If you do not see `By gum, you've done it!`, look at the output from the steps in part 1 to begin troubleshooting. Get TA assistance as necessary.

+# Installing and Updating the Linux App Manager
+
+For some things on your system, we will be using `apt` to install applications. The first thing we'll want to do is get that up to date with all of the latest versions and information
+
+**OPEN YOUR UBUNTU TERMINAL** and let's get started!
+
+1. Type `sudo apt-get update`.
+   - Provide your password, when prompted (***Note:*** *You will not have any visual feedback on your screen as you type. It is protecting your password by not displaying ANYTHING at all to the screen, but it is registering your key strokes.*)
+1. Once that is complete, type `sudo apt-get upgrade`. Press `y` when prompted.
+1. Once that is done, type `sudo apt autoremove`. This will remove any packages that are no longer needed.
+1. Install the "Build Essentials" kit with this command: `sudo apt-get install build-essential`

+# Install "Homebrew"
+
+Homebrew is a tool that simplifies installing applications on your machine. Think of it like an app store for your computer.
+
+---
+
+## Verify if Homebrew is already installed
+
+- In your terminal, run: `brew --version`
+  - *If output is similar to:* `Homebrew 3.4.11`
+    - Run: `brew update` to get latest updates
+    - Move on to [next page](./4-git.md)
+  - *If output is not similar to the above*, continue with instructions on this page.
+
+---
+
+In your terminal, enter the following command:
+
+- `/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`
+- You will be prompted several times along the way. Enter your password when prompted, accept all the defaults, say "Yes" if prompted. (***Note:*** *You will not have any visual feedback on your screen as you type. It is protecting your password by not displaying ANYTHING at all to the screen, but it is registering your key strokes.*)
+- Once the main installation finishes (could take up to 30 minutes), enter these commands, one at a time in your terminal - they should produce no errors, and do not produce success messages:
+  - `test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)`
+  - `test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)`
+
+Once the installation has completed, **run:**
+
+ `brew doctor`
+
+**if** return output is:
+
+```bash
+Your system is ready to brew
+```
+
+**or** return output is:
+
+```text
+Please note that these warnings are just used to help the Homebrew maintainers
+with debugging if you file an issue. If everything you use Homebrew for is
+working fine: please don't worry or file an issue; just ignore this. Thanks!
+```
+
+**then run:**
+
+`brew update`
+
+**else if**  return output is:
+
+```bash
+brew: command not found

+
+1. ```echo 'export BREW_HOME="/home/linuxbrew/.linuxbrew/bin"' >> $HOME/.zprofile``` 
+1. ```echo 'export PATH="$PATH:$BREW_HOME"' >> $HOME/.zprofile``` 
+1. ```reset```
+
+
+> **If `brew update` still fails to run, [click here](../../error/error.md) and do not continue with the following steps until you have Homebrew properly installed**
+
+## Install "gcc"
+
+In order for Homebrew to install other applications, it needs a tool called **gcc** to assist itself.
+
+Run this command in your terminal:
+
+`brew install gcc`
+
+When that completes, you will be returned to the command prompt and can move on to the next steps.
