Install the installer for Laravel projects:

composer global require laravel/installer

Place Composer's system vendor bin directory in your $PATH

If you are using bash in your terminal, run these commands:

echo 'export PATH="$PATH:$HOME/.composer/vendor/bin"' >> ~/.bashrc

source ~/.bashrc

If you are running zsh execute these commands:

echo 'PATH=/bin:/usr/bin:/usr/local/bin:${PATH}
export PATH' >> ~/.zshrc

source ~/.zshrc

Create your first Laravel project with the installer

I recommend to set a directory for your projects, if you are using valet you should run the valet park command inside that directory, inside that directory you can create new Laravel projects:

laravel new example

Now you can visit in the browser this site: http://example.test/

With the Laravel installer you can add multiple flags to set more features like create a github project with a branch, etc you can check this flags in the laravel.com site.
