Start writing how to add CrankShaft to a HubSpot portal

[TheWebTech]

Instructions will walk through uploading via FTP.

In Transmit I recommend using synchronize, and excluding .md files. HubSpot doesn't support markdown, which is why those files were done that way. makes it easy to prevent them from showing in the actual built site. If others think it makes sense for those files to be accessible in your HubL portal we can change to readme.html

These instructions will go on the documentation site.

This todo can be started here, documented in a markdown file or wiki page until the documentation site is ready.
