 Building from Source
 --------------------
 
-As discussed in the previous section :ref:`structure`, the algorithm that is provided by this project is mostly implemented in `C++ <https://en.wikipedia.org/wiki/C%2B%2B>`__ to ensure maximum efficiency (requires C++ 14 or newer). In addition, a `Python <https://en.wikipedia.org/wiki/Python_(programming_language)>`__ wrapper that integrates the algorithm with the `scikit-learn <https://scikit-learn.org>`__ framework is provided (requires Python 3.7 or newer). To make the underlying C++ implementation accessible from within the Python code, `Cython <https://en.wikipedia.org/wiki/Cython>`__ is used (requires Cython 29 or newer).

 Unlike pure Python programs, the C++ and Cython source files must be compiled for a particular target platform. To ease the process of compiling the source code, the project comes with a `Makefile <https://en.wikipedia.org/wiki/Make_(software)>`__ that automates the necessary steps. In the following, we discuss the individual steps that are necessary for building the project from scratch. This is necessary if you intend to modify the library's source code. If you want to use the algorithm without any custom modifications, the :ref:`installation` of pre-built packages is usually a better choice.
