As a web developer you may not be too concerned about the visual appearance of a website as you are tasked with producing functionality. You will probably have a good knowledge of HTML and CSS but will also be proficient in Javascript, PHP and a range of other languages. If you are new to Joomla! you will need support in developing or customising Joomla! extensions (components, modules, plugins, templates and languages). You will need information about the Joomla! Framework API and how to use it and will probably make extensive use of best practice example code. A strong understanding of Joomla!

We are now ready to proceed with the actual installation of the Joomla! program onto the Web server.

There are two ways of installing Joomla! The first – Web Browser Installation - can be considered easier than the second - Manual Installation - really as a result of the number of steps that are required.

Either will work with a little patience and concentration to detail.

Do not try to use both methods of installation, or part of one and part of the other for the same installation as this will cause you problems.
The only likely exception to this will be the installation of the Sample Data. If you choose not to install this initially during the Web Browser Installation, but then decide you want it after all, you can add the Sample Data provided no other content has been added since the installation took place even if you have subsequently deleted that content.
In this instance it would be easier and safer to re-install the package from the beginning, having first deleted the directory and database.
