Query: Example of categorification of a cluster algebra   We present here two detailed examples of additive categorifications of the
cluster algebra structure of a coordinate ring of a maximal unipotent subgroup
of a simple Lie group. The first one is of simply-laced type ($A_3$) and relies
on an article by Gei\ss, Leclerc and Schr\"oer. The second is of non
simply-laced type ($C_2$) and relies on an article by the author of this note.
This is aimed to be accessible, specially for people who are not familiar with
this subject.
