Summary, in English
This talk describes the reasons why $\eta$ and $\eta^\prime$ decays are
an interesting topic of study for both theory and experiment. The main
part discusses the results of the recent calculation of $\eta\to3\pi$
at two-loop order in ChPT. Some puzzling aspects of the results
compared to earlier dispersive calculations are highlighted.
I also like to remind the reader of the use of $\eta$ and $\eta^\prime$ decays
for studying the anomaly.
