Update 250 Chapter steps

[LanceMcCarthy]

The steps in the 250 course need to be updated to reflect the changes that have been made in Unity and in the project's scenes.

For example, the Player settings have moved under a different node and you no longer need to enable Mixed Reality explicitly.

It looks to me that this has been updated. Can you please confirm?

[LanceMcCarthy]

Hi Kurtis, I'll re-do the course from scratch to confirm and come back here to provide feedback. At first glance it does look like the steps have been updated.

### Feedback 1

Fix Unity hyperlink in the "Project Files" paragraph in the opening section of the course.

Summary: The paragraph looks like this

Project Files 1 - Download the files required by the project. Extract the files to an easy to remember location. 2 - This project requires the most recent version of Unity with Mixed Reality support.

Problem: The bold text above has a hyperlink is a duplicate of the HMD system requirements in the previous "Prerequisites" paragraph. There is no mention of Unity, or how to get it, in the target page.

Possible Options for Fix

• Remove the hyperlink
• Change the hyperlink to target Unity's home page
• Use this link that Unity uses to post the latest Mixed Reality supported version

Note that as of me writing this, Unity has finally combined HMD and Hololens support in the same version of Unity (v 2017.2 MRTP 5). Which is only available in the link in my 3rd suggestion.

I'm assuming Unity will merge all of this in the official 2017.3 release, but for now it's really the only way to complete the course as instructed (i.e. not need two separate versions of Unity one for Hololens and one for HMD).

If I find anything else, I'll come back to this thread and list them. Thanks!
