It looks like it is a good implementation crowdfunding that I could use to fund projects for my org at low cost (just credit card charges). Is there any info about its implementation on the civicrm website.
I read your question differently to Andy.
The MIH itself is simply a civicrm contribution page.
But there are also MIH 'content types' and the page at https://civicrm.org/make-it-happen is then a View (Drupal) based on the above Content Type and I suspect there is a fair bit of custom stuff happening in that View which means an 'export' of it won't give you it in a box.
While old, this covers a lot of it: https://wiki.civicrm.org/confluence/display/CRM/Make+it+Happen#MakeitHappen-HowdoIsubmitanMIHcandidate?.
