I use vagrant because I need PHP 7. I then have a ~/Homestead folder with the homestead.yaml file. I use the file to map my Code folder to the virtuel machine.

For each of my projects, I need to edit the homestead.yaml file and add the site like this:

sites:
  - map: larabook.app
    to: /home/vagrant/Code/laracast/public

 
  - map: larajobs.app
    to: /home/vagrant/Code/larajobs/public

For each site, I also update my hosts file.

In the Homestead folder:

vagrant up

Or:

vagrant up --provision

this is my homestead yaml file that runs 3 projects and each has their own local adress to be reached.

keys:
    - ~/.ssh/id_rsa

folders:
    - map: /www/sites/Code
      to: /home/vagrant/Code

sites:
    - map: dev.dev
      to: /home/vagrant/Code/dev/public
    - map: jp-it.dev
      to: /home/vagrant/Code/jp-it/public
    - map: got.dev
      to: /home/vagrant/Code/got/public

databases:
    - dev
    - got
    - jpit

variables:
    - key: APP_ENV
      value: local

# blackfire:
#     - id: foo
#       token: bar
#       client-id: foo
#       client-token: bar

# ports:
#     - send: 93000
#       to: 9300
#     - send: 7777
#       to: 777
#       protocol: udp

same as ChristianGerdes i run vagrant up instead of homestead because of php7

dont forget to run command "vagrant provision" after you update the yaml file
