I downloaded a theme, now what..?

Hi, I’m a bit confuzzled on what I am meant to do next, please can someone guide me through it..
An idiots guide if possible please

Here’s what I did and where I’m up to..

1) – I downloaded a bbpress theme via http://www.bbshowcase.org
2) – Created a folder called “my-templates”
2) — /public_html/wp-content/themes/itheme2-child/bbpress/my-templates
3) – Extracted files and placed the “static” (theme name) folder into /my-templates

And that’s it.. I have hit a brick wall…
Where do I go from here and have I done everything correct so far? (I’m guessing not lol)
