  -## Where did `/vagrant` go?
  +=== Where did `/vagrant` go?
   There is http://stackoverflow.com/questions/42074246/vagrant-error-unable-to-mount-virtualbox-shared-folders-guest-additions-vboxs[an issue with Windows 10 and VirtualBox 5.1.16] that prevents Vagrant from starting properly.  As a workaround, we've disabled sharing of folders.  Non-Windows users can edit the `vagrantfile` and re-enable the mount if desired.
   
   **UPDATE:** the issue has been resolved in VirtualBox 5.1.18.  The `/vagrant` folder is now mounted as usual.
  
positive.code: The system will look for an environment variable named `CORPORATE_PLAYS`.  If the shell running Vagrant specifies the variable such that it points to an Ansible project on GitHub, the plays will be run and the changes applied.  For example `export CORPORATE_PLAYS=kurron/ansible-pull-transparent.git` will result in https://github.com/kurron/ansible-pull-transparent.git[this playbook] getting run.  If the environment variable does not exist, the custom provisioning step is not run.
  
  === Applying Your Personal Customizations
  The system will look for an environment variable named `USER_PLAYS`.  If the shell running Vagrant specifies the variable such that it points to an Ansible project on GitHub, the plays will be run and the changes applied.  For example `export USER_PLAYS=kurron/ansible-pull-desktop-tweaks.git` will result in https://github.com/kurron/ansible-pull-desktop-tweaks[this playbook] getting run.  If the environment variable does not exist, the custom provisioning step is not run. **Important: use a copy of the project if you decide to apply customizations.** If you reference this project, you will get somebody else's customizations, including Git configuration, which most certainly you do not want.
  
  === Customizations: Linux Example
  1. create and/or edit `~/.bash_profile`
