Here we will introduce the basic definitions of bordered Floer homology.  We will discuss bordered Heegaard diagrams as well as the algebraic objects, like A_\infinity algebras and modules, involved in the theory.  We will also discuss the pairing theorem which states that if  Y = Y_1 U_\phi Y_2  is obtained by identifying the (connected) boundaries of  Y_1  and  Y_2, then the closed Heegaard Floer theory of  Y  can be obtained as a suitable tensor product of the bordered theories of  Y_1  and  Y_2.Note the different time and place!This is a 1.5 hour talk.
