Slice the avocado in half the long way, cutting only as deep as the pit then rotating the avocado around until it divides into 2 halves. 

Remove the pit, and use a spoon to scoop the avocado out of its skin and into a bowl. 

Mash the avocado with a fork. 

Add the seasonings, and any optional ingredients, and mix well. 

Taste the guacamole and continue to add additional seasonings to taste.
