A short, and
definitely not a complete representation of $\eta$
production processes on hadrons is given. First of
all, the different ways of obtaining the $\pi N
\rightarrow \eta N$ and $\eta N \rightarrow
\eta N$ amplitudes are presented. After that, an
overview of results obtained using these amplitudes as
input for calculating processes
like: $ N N \rightarrow NN \eta$, $pd
\rightarrow \eta \ ^3 He$, $\pi d \rightarrow \eta
NN$ and $\eta d$, $\eta \ ^3 He$ and $\eta \
^4 He$ as well as $\eta$-light nuclei bound
states, will be given. The experimental and
theoretical results will be reviewed. The
opened problems and the way how to solve them will
be presented.
