If you intend to contribute your applications to the MIRTK distribution, develop your tools
either in a fork of the MIRTK Git repository or a your own MIRTK Package
with the common file organization for MIRTK Packages and the appropriate CMake_ configuration
-files. See some of the already available modules in the ``Packages/`` directory of the
+files. See some of the already available modules in the `Packages/` directory of the
MIRTK source tree as reference. Examples of MIRTK Packages are the
[Deformable](https://github.com/MIRTK/Deformable) and
[Volumetric Mapping](https://github.com/MIRTK/VolumetricMapping) modules,
each developed in their own respective GitHub repository.
Template files for the creation of a new MIRTK Package can be found in the
[Templates](Templates/mirtk-module) directory. These template files can be customized using
-the [basisproject](http://opensource.andreasschuh.com/cmake-basis/howto/use-and-customize-templates.html#use-a-template)
