 ## Usage
 - TODO (Check examples for now)
 
-## API documentation
-This project documents the library API using [Doxygen](http://www.doxygen.org).
-It is planned to make generated and up-to-date API documentation available online.
-
-To generate the API documentation,
-Doxygen, as well as [Graphviz](http://www.graphviz.org/) should be installed.
-(Note that on Windows, it may be necessary to add the Graphviz binary directory
-(something like `C:\Program Files\Graphviz2.38\bin`)
-to the `PATH` variable manually.)
-With Doxygen and Graphviz installed, issue the command
-`doxygen` from the command line in the main project directory, which will
-generate the API documentation in HTML format.
-The just generated `api-doc/index.html` can now be opened in a browser.
