The Virtual Element Method (VEM) is an extension of the Finite Element Method(FEM) used for handling polytopal meshes. This paper provides a briefintroduction to the VEM for a two-dimensional Laplacian problem. Additionally,it highlights the differences between a VEM implementation and a FEM code,emphasising the main challenges associated with the VEM.  Furthermore, this paper presents a possible approach to address thesechallenges: vem++, a c++ library specifically developed for working with VEMdiscretisation. The library is designed to handle various partial differentialequations in two or three dimensions, arising from both academic andengineering problems. Its flexible design allows for the seamless integrationof new features, such as novel polytopes' quadrature rules, solvers, andvirtual element spaces.
