+\section structure Directory Structure
+
+The modules are sorted in subdirectories by their category:
+
+ - kern/ - Simple multitasking kernel implementation;
+ - drv/ - Hardware drivers;
+ - mware/ - Algorithms, containers and other standalone code;
+ - io/ - Infrastructure of I/O-related modules for hosted applications;
+ - os/ - OS-abstraction layers for hosted environments;
+
+The top-level directory contains a few support headers that are meant
+to be usable by any C or C++, embedded or hosted application.  The
+top-level directory also contains a few example templates for files
+that are meant to be customized on a per-application basis.  These
+files are hw.h, config.h, verstag.h and arch_config.h.
+
+To achieve the highest possible reusability, most DevLib components
+are designed for fine-grained modularity and minimal external
+dependencies.  Most non-essential features can be configured out for
+applications with small memory footprint requirements.
