I've just created a quick video walk through of how to install Joomla on a local wamp environment. Mamp is one of those must have tools that all website developers use. It allows the developer to build and modify a database driven dynamic website on your local computer without uploading it to the internet. This allows for very quick development. Whilst for the inexperienced it might seem very complicated, rest assured that with enough practice you will become very quick at doing this.
