Place to put your shared template files under. Node Bootstrap is, by default, pre-configured for Handlebars templates, but you can use any other Express-friendly templating engine, even: alongside Handlebars, if you want. Typically templates should be encapsulated in their respective modules (which also have views folders, see the sample modules under “lib”), but in case you need to share some templates across various modules: this is where you’d do it.
