 It used to be a selective copy of the [Catmandu tutorial](https://librecatproject.wordpress.com/2014/12/01/day-1-getting-catmandu/) but adapted for [Metafacture](https://github.com/metafacture).
 The Catmandu tutorial was created by [@phochste](https://github.com/phochste). It is great if you want to learn [Catmandu](https://github.com/LibreCat/Catmandu). So try it out.
