Good, lets try if LaTeX already works by creating a new file by clicking the icon in the top left corner of Texmaker. The manual tells how to make other symbols. Paragraphs are separated by one or more blank lines. An excellent plug-in for Excel is Excel2Latex.
If you run into any trouble and you could not produce a PDF file, please check if your Texmaker has automatically identified LaTeX installation correctly. Once we have started writing, the most left one will show the structure of our document, namely headings etc. At this point I need to say, that we are going to translate our document into PDF.
The class is based upon the standard report class around which most people design their thesis. As not everyone writing in LaTeX is a nerd, we are about to use a special text editor also called IDE for integrated development environment that does some helpful things for us like syntax highlighting, auto completion and creating the final PDF file by only a mouse click.
If you are one of the Linux guys, you might also have a look at Kile. For example, if you are a software developer, you might want to display source code of algorithms in your thesis.
The Mathematical Institute Linux systems have the class and logo files installed by default. We will see later on how we can install and use them.
