 ## Building
 ### Linux
-Install the QtCore, QtGui and QtWidgets libraries and build headers, along with the qmake tool. Depending on how qmake is installed, type `qmake && make -j3` or `qmake5 && make -j3` in a terminal to build, you can replace -j3 with the number of processor cores used for the compile process.

 The above should place the qteletextmaker executable in the same directory as the source, type `./qteletextmaker` in the terminal to launch. Some Qt installs may place the executable into a "release" directory.

 By checking "raw values" it is also possible to view and edit the raw Address, Mode and Data numbers of the triplets. When editing triplets this way, remember that address values 0-39 select a column triplet which has one set of modes and address values 40-63 select a row triplet which has a different set of modes.

 ### Setting the Active Position
 The Active Position, whether set explicitly by a "Set Active Position" triplet or by a row or column triplet, can only be moved in screen address order i.e. from left to right within a row and then from top to bottom across rows. In other words:
