edit your terminal code example

Example: change ps1 variable iterm

When you have iTerm2 installed follow these steps:

1) Open iTerm
2) Click the voice "iTerm2"
3) Select the voice "Install Shell Integration" 
   (it will ask if you want execute the command inside the shell, accept)
4) Type "open ~/.zshrc" to open .zshrc where you'll change the PS1 value
5) At the bottom of the .zshrc file set your PS1 variable

Example: 
I wanted to see the path of the current folder where I'm currently working in:
export PS1="%d >> "

This is what you'll see on the terminal if you're (for example) in Documents:
/Users/your_username/Documents >>
