1. Log in to the WordPress Dashboard.
2. From the Dashboard menu, go to Posts and click on Categories.
3. Enter the following details in Add New Category:
Name: Enter your category name, such as Computer.
Slug: Enter a slug name or leave it blank.
Parent: Leave this at None, or should you select a category, it will become a sub-category of your chosen category.
Description: Enter your category description, or simply leave it blank.
4. Click on Add New Category.
And you have just created a new category.
