 ## Overriding how pages are drawn
 
 By default, every time you navigate to a menu structure you'll see an auto-generated page. You can also provide your own custom pages, each page must extend from `PanelPresentable` and can be added to the navigation manager, in this case the `JfxNavigationHeader` in `RemoteConnectionPanel` using `navigationManager.addCustomMenuPanel(subMenuCustom, myPanelPresentable)`. By the time the `RemoteConnectionPanel` is constructed you know which board/UUID you're connected with, and can then determine if you want to override drawing for any submenus.

+In either case the create project process will output a starter project very similar to this working project, you can then decide which of the optional components you want to keep, these are the components that are in the `optional` package. By default it will have a Jetty webserver that serves up browser based EmbedControlJS and a JavaFX UI.

+Where `com.example.menu` is the Java package to put the source code in, and the project will be called "SimpleProject".

+### From TcMenu Designer UI
+
+Go to the `File -> New` option and select to create a Java/Raspberry PI project. Ensure the package name is filled in with the Java package name.

+### Loading into an IDE

+We use IntelliJ, but many IDEs support Java and you can consult their documentation for importing a maven (pom.xml) project. In IntelliJ simply create a new project from the POM file.
