Updates for Readme.md

[cutaway]

The following are a few recommendations for different sections.

Prerequisites

Recommendation: Add the following bullet

• Disable Hyper-V (Windows and Virtualbox only) - follow the Resolution instructions provided by Microsoft to disable and enable Hyper-V (requires reboot) - https://support.microsoft.com/en-us/help/3204980/virtualization-applications-do-not-work-together-with-hyper-v-device-g

Initial Install

Recommendation: Update bullet 3 to the following and add a fourth step. (This should help people from immediately trying to log in *then* finding the **NOTE**.) Also, moving the step for running separate target systems helps people understand it is a separate topic. The last part helps people that don't know Virtualbox keep from trying to adjust the display by installing virtualbox-guest tools (which are not in distro and are not necessary).

3. From a command-line terminal in the project directory, run the command vagrant up. Then sit back and wait for it to finish. NOTE: The Guest VM's window will open with the CLI while provisioning is still ongoing. It's best to leave it alone until the vagrant up command fully completes.
4. Immediately after the first time start up it is recommend you do a restart using vagrant reload.

Running Separate User / Target Systems

• Just running the vagrant up will build the primary target, which is a single VM with both the user environment and the targets.

• You can run vagrant up userenv and vagrant up target to build separate virtual machines for those purposes.

• Add * the following to the end of this section

  Virtualbox Display

• To automatically adjust the display resolution, do the following:

  • Select Virtualbox Menu -> View
  • Click Auto-Resize Guest Display
  • Resize Virtualbox window and display should change to fit window size.
