+High-level protocol logic
+=========================
+
+Classes defined in this directory implement some high-level functions of UAVCAN.
+
+Since most applications won't use all of them at the same time, their definitions are provided right in the header
+files rather than in source files, in order to not pollute the build outputs with unused code (which is also a
+requirement for most safety-critical software).
+
+However, some of the high-level functions that are either always used by the library itself or those that are extremely
+likely to be used by the application are defined in .cpp files.
+
+When adding a new class here, please think twice before putting its definition into a .cpp file.
