+Building the sqlite logging driver
+-----------------------------------
+
+You can use the driver by including the src/logging/drivers/sqlite/log_storage_sqlite.c file into your application build. 
+
+On Ubuntu Linux (and simpilar Linux distributions) it is enough to install the sqlite dev packages from the standard repository. For other OSes (e.g. Windows) and cross-compiling it is recomended to download the amalagation source code (from https://www.sqlite.org/download.html) of sqlite and copy them to the third_party/sqlite folder.
+
+On windows the cmake skript will detect the sqlite source code and also creates the example project for logging.
