Jekyll Joys

Today I decided that some of my pages should get a top navigation menue. I read a little in Jekyll’s manuals, and after (admittedly, hours) I understand how it works. There are basically two ways (1) add apppropriate front matter material, or (2) use a YAML file in the _data directory. So far I went with (1) and decided to also switch the site image on/off, again using Liquid and front matter.
