If you have a hosted server you may not be able to create a database. If so skip this page.
Most modern versions of PHPMyAdmin have a New (create database) button on the left but for now click on the Databases tab at the top. There are two form fields near the top now. Put the new database name in as intsql. You could choose utf8mb4_unicode_ci in the drop down but it will default to that because of the setting on the front page.
Click the Create button. It should jump you to the new database ready to create tables.
You will create databases to collect together related data. This database will be for your pages from this tutorial. You might also be building other sites and you will create separate databases to keep things organised.
