The one reason I have been working to build a child theme is to provide the ability to preserve changes on the master theme updates. See a child theme pulls everything from a parent theme EXCEPT where you make modifications to those files.
Where you make changes to those files your child theme can deviate from the main theme. This is how many companies can sell child themes based on other core themes. This is a large step forward in customizations as it allows for you to change values and keep them until you remove them.
Of note, this does mean that a child theme can break if the main theme deviates from core coding and, for example, rewrites a chunk of code because your child still thinks it is the old file and may cause some ripples on an update.

Just like Acabado or any other theme to install you go to your theme folder and upload. Then you choose to make it Active.
As always I can test most the functionality but with every theme and plugin combination, there could be odd issue to investigate, if you are running the child theme please comment below here to let me know. If we find it to be a core Acabado issue we will submit the bug report to ensure that Jim and Ricky can get it resolved with the Development team.
I will continue to update this each time updates come as soon as I know it is working I will update the versioning next to it.
