Pointers Structure (C programmaing)

i have a struct that I don't understand :

typedef struct {
    int x;
    int y;
} Position;



typedef struct {
    int id;
    Position upper_left;
    Position lower_right;
    int priority;
} *Window_Description;

I don't understand why the struct *Window_Description has an asterisk before with? It's a pointers to the structure ? Because when I will create some Window_Description, it will be pointers ?

I'm kinda new in C thanks for helping!
