# In this configuration file, I tried to accommodate more information with comments and various ways of managing Vagrant settings.
# These are the most used options. To determine the name of the birdge adapter, use VBoxManage.exe.
# PS C:\Program Files\Oracle\VirtualBox> .\VBoxManage.exe list bridgedifs
# Here Name is the name of the adapter that needs to be written in the Vagrantfile.
# Now you can raise the test site.
