    I think you should explain installation proccess because the readers should know that some files or directories must be deleted to use XAMPP or WAMP etc.


    Step-by-step Installation Guide for XAMPP:-

    1) Double click on Xampp Installation file.
    2) Click "Next" -> "Next" -> "Install".
    3) After installing the files, Click "Finish".
    4) open the folder "c:" -> "xampp" -> "htdocs" .
    5) Delete the "index.php" file.

    To start the XAMPP :-

    1) click on "XAMPP Control Panel" icon on the Desktop , then a small window of control panel will appear.
    2) Click on "Start" infront of "Apache" & "Mysql" .

    Important Instruction :-

    Save your project files in "c:" -> "xampp" -> "htdocs" . Make a separate folder for each project here or keep all files of a single project in the "htdocs" folder.
