I'm a huge fan of Vimwiki (https://github.com/vimwiki/vimwiki https://github.com/vimwiki/vimwiki). I've got multiple wikis for different projects I work on. I keep the wikis in a Dropbox folder to sync them across devices. Since I use markdown for my Vimwiki files, I can edit them fairly easily - I use Editorial on iOS when I'm away from a computer.
