WordPress
WordPress is a massively powerful, free ‘of-the-shelf’ content management system. It’s quick to set up and simple to use.
Building with WordPress means we can create a wide variety of websites that will grow with you using a vast library of plugins to quickly add common functions, like Twitter feeds. It also means we can take over from someone elses code and instantly know how it works.
WordPress has always been built with speed in mind, and this really shows. It’s also built in a way that lets us easily add real custom functionality into it, enabling us to do pretty much anything with it.
