-Compile XGBoost using MinGW
----------------------------
-After installing `Git for Windows <https://git-for-windows.github.io/>`_, you should have a shortcut named ``Git Bash``. You should run all subsequent steps in ``Git Bash``.
-
-In MinGW, ``make`` command comes with the name ``mingw32-make``. You can add the following line into the ``.bashrc`` file:
-
-.. code-block:: bash
-
-  alias make='mingw32-make'
-
-(On 64-bit Windows, you should get `MinGW64 <https://sourceforge.net/projects/mingw-w64/>`_ instead.) Make sure
-that the path to MinGW is in the system PATH.
-
-To build with MinGW, type:
-
-.. code-block:: bash
-
-  cp make/mingw64.mk config.mk; make -j4

-See :ref:`mingw_python` for buildilng XGBoost for Python.
