How to download macro from GitHub?

Bernardo Vasconcelos uploaded a macro to use Tinderbox more easily on to GitHub. How do I download and install it. It seems to be broken into many files of Applescript. https://github.com/bcdavasconcelos/DEVONthink-3/find/905e311b8cc1a8294280ad2751851a8a46cdac53
I am a total newbee.
Thanks,

The link you provided does NOT link to any KM Macros. They are all AppleScripts.
Furthermore, for some strange reason he has embedded the scripts in a markdown file -- highly unusual.

IAC, to get to the AppleScript, you can just copy from the displayed Markdown page, or click on the "RAW" button to display plain text:

If you were expecting a KM Macro, then you need to contact the author for further instructions.

I am sorry. I now see a link back to KBM forum. But it does not work. The discussion comes from EastGate TBX forum http://forum.eastgate.com/t/keyboard-maestro-macro-group-as-a-menu-for-tinderbox/2583
Apparently the file is in Keyboard-maestro but I can't find it. It links devon think 3 and TBX using KBM (I think)
