+Compiling QCustomPlot as shared library:
+  - Make sure the amalgamated QCustomPlot source files (qcustomplot.h/.cpp) are in the directory above sharedlib (two directories above the .pro files).
+  - Run qmake; make; in the sharedlib-compilation directory. This will create two library versions: "qcustomplot" for release mode and "qcustomplotd" for debug mode.
+    For example, on Unix this will create libqcustomplot.so and libqcustomplotd.so and some softlink files to those shared library files.
+    On MS Windows it will create corresponding .dll files.
+
+Compiling an application that uses the shared library:
+  - Copy all created library/softlink files from the previous step to the sharedlib-usage directory
+  - run qmake; make; in the sharedlib-usage directory. This will build the application.
+
+Running the application:
+  - Make sure the application executable can find the shared library files:
+    On MS Windows it is sufficient to have the library .dll files in the same directory as the executable.
+    On Unix you have at least two options: You can specify the current directory in the LD_LIBRARY_PATH variable (call in
+    terminal: "export LD_LIBRARY_PATH=." before launching the application from the same terminal session). This is useful
+    for testing if it works. The other option is to install the library files to one of the default locations for shared
+    objects: /usr/local/lib or /usr/lib for example.
+  - Launch the application.
