By some definitions that can be found on-line, Jekyll is a simple, blog aware, static site generator. But, what exactly does this means? A static site generator transforms input, typically text in lightweight markup languages (like Markdown-Syntx) to static HTML files, using templates and filters.
Jekyll is able to use a set of HTML templates, take the content separetly (writen in Markdown) and then generate the static HTML files. Well, like the definition of static site generator says, right? but Jekyll do it with extremely simplicity and pretty good performance.
This site is powered by Jekyll.
Based on a Pixyll theme.
