The easiest way to build and install _Labcontrol_ is to open the `labcontrol.pro` file with _Qt Creator_ and build the project. Afterwards _Labcontrol_ can be started by running the created executable file. To build correctly _Qt5_ has to be available and must be know to _Qt Creator_.
To work properly _Labcontrol_ requires a file named `labcontrol.json` + the folder named `icons` (inside of `data`) in either `/usr/local/etc/Labcontrol` or `/etc/Labcontrol` or next to the Labcontrol binary. This directory must be created, the existing dummy file be copied there and afterwards be modified according to the laboratory's needs. All _z-Tree_ executables should reside in sub-directories of `/opt/z-Leaves` following the naming scheme `zTree_X.Y.ZZ`.
Receipt creation requires at least one receipt template in `/usr/local/share/labcontrol`. The name of the header file should match the pattern `NAMETHEHEADERSHALLHAVE_header.tex` to be recognized.
