  We give a short introduction to the contact invariant in bordered Floer
homology defined by F\"oldv\'ari, Hendricks, and the authors. The construction
relies on a special class of foliated open books. We discuss a procedure to
obtain such a foliated open book and present a definition of the contact
invariant. We also provide a "local proof", through an explicit bordered
computation, of the vanishing of the contact invariant for overtwisted
structures.
