Karnaugh maps how i put them exactly
F is in SOP form in terms of 4 variables A,B,C,D. Various Elements in the SOP expression for F are called Minterms. 

1)  4 variables, means K-map can be drawn as 4x4.

2) Total 16 cells would be there. Each cell in K-map corresponds to a minterm. 

For eg. first cell --> 0000 --> A'B'C'D'

3) Look at all the minterms present in the SOP expression for F, and put '1' in the corresponding cell of the K-map.

4) Fill the rest of the cells with 0.
