PolyominoIdeals: a package for Macaulay2 to work with the inner $2$-minor ideals of collections of cells

Let P be a collection of cells and IP be the associated ideal of inner $2$-minors as defined by A. A. Qureshi in 2012. In this paper, we provide a description of the package PolyominoIdeals for the computer algebra software Macaulay2. More precisely, this package provides some functions that allow to define the ideal IP in Macaulay2 and to compute its algebraic invariants or verifying its algebraic properties. We explain the usage of these functions and also give some examples.
