	It is suggested to start simply, test the result, and then add more decorations one at a time. The command interface may appear daunting at first but you should get used to it before too long. Manual placement of decorations is a bit of a pain and time-consuming, but it is hoped that there will soon be a new [[WxPython-based_GUI_for_GRASS#Cartography_tools\|wxGUI map-composer wizard]] which will act as a front-end to the program, greatly speeding up this part of the task.
