#### Abstract

This paper studies the singularity category of a locally bounded $k$-linear category $\mathscr{C}$ with radical square zero. Following the work of Bautista and Liu [4], we give a complete description of $D_{sg}(\mathscr{C})$. Examples are provided to show how one can easily compute the generators of $D_{sg}(\mathscr{C})$ from the quiver of $\mathscr{C}$.
