Bolt is a tool for Content Management, which strives to be as simple and straightforward as possible. It is quick to set up, easy to configure, uses elegant templates, and above all: It’s a joy to use. Bolt is created using modern open source libraries, and is best suited to build sites in HTML5 with modern markup.
