description: The heart of TiddlyWiki is it's microkernel. This section will describe what bare mechanisms are included in the microkernel and how additional modules are loaded.
This section describes the architecture of the ~TiddlyWiki-kernel. ~TiddlyWiki is based on a micro-kernel which provides only a small stack of functions. This design decision was made to introduce a cleaner mechanism for customisation of ~TiddlyWiki. This section also describes the data-model of ~TiddlyWiki called tiddler. And it gives a overview to the module system which developers can use to extend the functionality of the ~TiddlyWiki application.
