 Vector heads and tails
 ======================
 
-Many methods in PyGMT allow plotting vectors with individual
-heads and tails. For this purpose, several modifiers may be appended to
-the corresponding vector-producing parameters for specifying the placement
-of vector heads and tails, their shapes, and the justification of the vector.

-To place a vector head at the beginning of the vector path
-simply append **+b** to the vector-producing option (use **+e** to place
-one at the end). Optionally, append **t** for a terminal line, **c** for a
-circle, **a** for arrow (default), **i** for tail, **A** for plain open
-arrow, and **I** for plain open tail. Further append **l** or **r** (e.g.
-``"+bar"``) to only draw the left or right half-sides of the selected head/tail
-(default is both sides) or use **+l** or **+r** to apply simultaneously to both
-beginning and end. In this context, left and right refer to the side of the
-vector line when viewed from the beginning point to the end point of a line
-segment. The angle of the vector head apex can be set using **+a**\ *angle*
-(default is 30). The shape of the vector head can be adjusted using
-**+h**\ *shape* (e.g. ``"+h0.5"``).

 In the following, we use the :meth:`pygmt.Figure.plot` method to plot vectors
 with individual heads and tails. We must specify the modifiers (together with
 the vector type, here ``"v"`` for Cartesian vector, see also the
-:doc:`Vector types example </gallery/lines/vector_styles>`)
-by passing the corresponding shortcuts to the ``style`` parameter.

 For further modifiers see :gmt-docs:`plot.html#vector-attributes`. Please note
 that vectors were completely redesigned for GMT 5 which separated the vector
