A static Jekyll site hosted by github, created from scratch in a few hours. The owner of this holiday letting needed a web-presence to be accepted onto various letting portals.
This work-exchange project was profitable for us both. Shelly gained her web-presence and started taking bookings, while I was given a weeks free use of the cottage.
Furthermore this was a great excuse to try the GitHub Jekyll servers. I now use Jekyll in many of my projects to keep processing to a minimum.
