135 -With the mouse over the SCT file in the project explorer, perform //Right Click > Run As > KiCo Compilation.//
137 +The model is now ready to be compiled. Compilation is done in the background when the project is built. There are two ways to build a project: manually using //Project > Build Project//, or automatically via //Project > Build Automatically//. If the automatic build is enabled, resources are built when they are saved.
136 136  
137 -A launch config is created, which compiles the model to Java code and creates wrapper code from the annotations in the model file. Afterwards this output is compiled and deployed to the Mindstorms brick, by using the launch shortcut from the leJOS plugin. If any errors occur, you can see them in the Console View.
139 +Building the project will create a new folder //kieler-gen// in which all results are saved. This includes the compiled code from the model, an executable simulation for the model and wrapper code that is ready to be deployed to the Mindstorms Brick.
138 138  
139 -For a deeper understanding of the project launch and initialization, take a look at the [[wiki page for Prom>>url:http://rtsys.informatik.uni-kiel.de/confluence/pages/viewpage.action?pageId=13762626||shape="rect"]].

151 +It is necessary to exclude the simulation directory and org.json directory inside kieler-gen from the NXT project specific build via //Right Click > Build Path > Exclude//. Afterwards the project has to be build again to remove all error markers in these directories.
