  The Matrix Element Method has proven to be a powerful method to optimally
exploit the information available in detector data. Its widespread use is
nevertheless impeded by its complexity and the associated computing time.
MoMEMta, a C++ software package to compute the integrals at the core of the
method, provides a versatile implementation of the Matrix Element Method to
both the theory and experiment communities. Its modular structure covers the
needs of experimental analysis workflows at the LHC without compromising ease
of use on simpler and smaller simulated samples used for phenomenological
studies. With respect to existing tools, MoMEMta improves on usability and
flexibility. In this paper, we present version 1.0 of MoMEMta, together with
examples illustrating the wide range of applications at the LHC accessible for
the first time with a single tool.
