+Introduction
+============
+
+novelWriter is a simple multi-document plain text editor using a modified
+markdown syntax to apply simple formatting. Additional features are available
+through special meta data commands. These make it possible to generate an
+overview of the entire novel project and how the various files are
+interconnected.
+
+The user interface is intended to be as minimalistic as practically possible,
+and most features are accessible through the menu and through keyboard
+shortcuts. The colour scheme of the user interface can be modified with various
+themes, and new themes are fairly straight forward to add. They are separated
+into gui and syntax themes, and can be found in the themes folder in the source
+code.
+
+The tree view has various sections for the various types of supporting files
+that the User may want to add to the project. The novel itself lives under its
+own root folder, and export features are in the process of being added. These
+will include HTML, open document and PDF via LaTeX.
