Where should be located the folder with the documentation and html layout

Hello to all. Sorry for my newbie question.

In my project I first create a layout in HTML, where I use sass and grunt. And then I transfer this folder with the layout (folder name: markdup) to the Laravel project. And the question is where this folder should be located?

I have three options:

-1. Remove the folder with the layout and documentation and get such a structure

/docs
/markup
/project
.../app
.../bootstrap
...etc

-2. Put the folders inside the project:

/app
/bootstrap
...
/docs
...
/markup
/public
...etc

-3. Put in a resources folder

/public
/resources
.../docs
.../lang
.../markup
...etc

Which of this options is more logical? Thanks a lot in advance
