28 The above generates the default makefiles for your configuration, which is typically
29 the release build if you are using precompiled binary Qt distribution. To build both
30 debug and release, or one specifically, use one of the following qmake lines instead.
31
37 For debug builds:

50 If you want to leave out demos and examples from the build you can use
46 For both builds (Windows/OS X only):
51 the following config with qmake:
47 qmake CONFIG+="debug_and_release build_all"
52 CONFIG+=nomake_demos_examples
48 make
53 For some embedded environments, such as VxWorks, all examples and demos
54 may not be applicable. There it's recommended to use the above mentioned
55 config option.

57 If you want to install the libraries to your Qt library directory use:
50 After building, install the module to your Qt directory:

77 documentation is prioritized for Qt5. We recommend building the documentation using Qt5,
69 Both Qt Assistant (qtcharts.qch) and in HTML format (qtcharts subfolder)
78 if you want to do it yourself. Creating the documentation using Qt4 also works, but some
70 documentation is generated.
79 pages are not generated correctly, such as the 'List of All Members' page for all C++ and
