+# Folder instructions
+
+This directory contains the material to build the project documentation with `doxygen`.
+
+## Instructions
+
+The project documentation is managed by `doxygen`, a documentation generator that is able to extract documents directly from properly formatted comment sections of the source code. To build a local instance of project documents, make sure that you have `doxygen` installed, then `cd` into the document source folder (the folder containing the `conf.dox` file, specifically `np_tmcode/doc/src`) and then run:
+```
+doxygen conf.dox
+```
+
+`doxygen` will automatically build the HTML structure to cover all the documented source code and it will additionally provide the fundamental structure to prepare a LaTeX formatted version of the documents. These two outputs will be placed, respectively, under the folders `np_tmcode/doc/build/html` and `np_tmcode/doc/build/latex`.
