In this demonstration we present an Eclipse plug-in, called COCONUT (COde COmprehension Nurturant Using Traceability), that shows the similarity level between the source code under development and highlevel artefacts the source code should be traced onto. Also, the plug-in suggests candidate source code identifiers according to the domain terms contained into the corresponding high-level artefacts. Experiments showed that the plug-in helps to produce source code easier to be understood.
