Hello all,
After much time considering this, I've begun creating what I hope to be a series of posts on my blog about building Joomla! templates from scratch using the T3 Framework. Some time ago, I asked if this sort of things would be of interest and got positive feedback.
My first post on the topic is about the tools needed to get started with the development and I think that it's a good starting point. Love to hear what you think, either here or by giving me comments, reactions, or ratings on the blog, which can be found here:
