How to add to installed homestead project from github?

I have installed homestead with Vagrant on my ubuntu 20
and in my /home/master/Homestead/Homestead.yaml file I added phpmyadmin by adding one more site :

    - map: /_wwwroot/lar/company/code/blog
      to: /home/vagrant/code/blog

    - map: /_wwwroot/lar/company/code/phpMyAdmin
      to: /home/vagrant/code/phpMyAdmin

    - map: blog.test
      to: /home/vagrant/code/blog/public
    - map: phpmyadmin.test
      to: /home/vagrant/code/phpMyAdmin
    - blog_test

2 sites above use 1 batabase blog_test.

As I am new in Homestead I did it by some youtube step by step instructions.

Next I need to upload from github laravel project and wonder how have I to setup it ?

I suppose that I need in Homestead.yaml to add one more mapping lines for “folders:” and “sites:”
but which changes have I to apply to databases options ?
Which else options have I to use ?
