 Install the software

+**Custom build**
+
 Before you can start using the MIRTK or develop your own MIRTK applications,
 you have to install the desired modules and available applications on your
 system including their prerequisites. For a manual installation of the MIRTK,
 please follow the :doc:`download` and :doc:`install` instructions which
 list the third-party libraries required by each module and describe how to
 build the MIRTK from its publicly available source code.
 
+
+**Using Docker**
+
 Instead of manually installing the MIRTK locally on your system, you can use
 the pre-made `biomedia/mirtk <https://hub.docker.com/r/biomedia/mirtk/>`_
 Docker image to run the :doc:`commands` inside a `Docker container`_.
 For a guide to install and use Docker_, see the `official docs <https://docs.docker.com>`__.
