<p>In the .env file you need to change 3 things. 1. change DB_DATABASE to equal the database you created earlier. 2. Change DB_USER to the database user you created earlier (and hopefully added to the database with all privileges). 3. Change the DB_PASSWORD to the password you set up for the database user you added to this database. Special Note: Older versions of Craft CMS required you to create your own SECURITY_KEY, but newer versions have this set up for you. You can change this to your own key, or generate one from <a href="https://randomkeygen.com/">https://randomkeygen.com/</a>.</p>
