I notice that, with regard to installing the Unity8 desktop preview, the blog post links to instructions found on another blog post.
Suggestion: Although the instructions found on linked blog post are currently accurate, I suggest that you consider instead linking to instructions that, if needed, can be more readily updated, namely those instructions found here: https://github.com/ubports/unity8/
Also, linking to the instructions found at the above suggested location promotes filing issue reports for the Unity8 preview in the appropriate place, namely in the Unity8 issue tracker.
