Customizing BP Social Theme

Ok so I read...

https://premium.wpmudev.org/wpmu-and-buddypress-themes/what-are-parent-and-child-themes/

In ref to The BP Social Theme...

My aim is not only to be able to work on this on my local hard drive (Windoze PC) but if possible also preview it there prior to making the changes. I want to customize the html/css, images, etc. layout, colors etc. as much as possible.

I do understand creating the file structure etc. in the child's folder so no problem there or no doubt I will post back.

"See Next:" There is no next!

So without any further confusion help will be appreciated.
