Source is a 'micro' framework that provides the basis to build great sites using RapidWeaver and Stacks. Source is different from the larger frameworks in that it doesn't try and be all things to all people - i.e it doesn't come with an abundance of different stacks. Instead the thinking behind Source is that we will just supply a core set of (really powerful) stacks and if you, as the web designer, need a slider or an accordion etc, then you just use your favourite ones from your Stacks collection, or you find the perfect specialised one on the RapidWeaver Community site.
The key things to know about Source are that it is lightweight, modern, fast and....FREE!
Note: This video was created using an earlier version of Source however although things may look a bit different now the premise remains the same.
The 'Welcome to Source' project file is a great way to see some examples of what Source can do (with and without the Addon pack). There are extensive 'developer notes' within the project files to explain different settings etc.
