Include composer create-project command in installation example

[tiffany-taylor]

I am new to the Laravel ecosystem, and the wording install Jetstream into your new Laravel project contradicted the red warning box further down in the Installation docs about "Jetstream should only be installed into new Laravel applications." In my mind, the ambiguity was "do I need to include the Laravel framework first before I composer require Jetstream?"

Again, new to the ecosystem, so I wasn't sure if the artisan command only came from the Laravel framework. My assumption was that "creating a new Laravel project" would mean that Jetstream included the necessary bits to start a new Laravel project, and that I shouldn't start with composer create-project laravel/laravel.

After asking a couple people, I was informed that I was wrong, and that yes, I need to create a Laravel project first, before installing Jetstream. I figure that revising the docs may clear up any ambiguity for other new users.
