In this note, we give a short proof for a theorem on the competition numbers of diamond-free graphs: If a graphGis diamond-free, then the competition number ofGis bounded above by, wheredenotes the set of non-simplicial vertices inGanddenotes the minimum number of cliques that cover all the neighbors of a vertexvinG.
