Great start we have, I'm proud!
You have a data called "*.sql" in which * could be anything inside your server's folder, open that data with any text editor of your choice, copy the content with ctrl+c. You will now need to login to your phpmyadmin which should be
http://localhost/phpmyadmin <- mind this could vary depending on which webserver you installed, you're using windows, which means I wont support you for a long time as this is completely unprofessional and super buggy. Once you're logged to your phpmyadmin page, create a new database, click on it, navigate to the tab SQL, paste the code that you copied from the *.sql file and click on Ok. Tables will be created.
Once your tables were created just open a new tab on your browser, type
http://localhost/ and you'll be redirected to the page you made a screenshot of, now copy all of the content of this text field and do the same as you've done with the *.sql file, once you're done with that proceed to the config file of your AAC (in this case Znote), which will be in the webserver's www or html folder. The config file name is config.php, it is there, use a text editor to open it, read and modify the files to your needs, There are plenty of questions about this on OTLand, you're more than welcome to use the search function.
After you edited the configuration file of your AAC, move on to the config.lua inside your distribution folder, configurate it right (give the username, password and database name and port which should be 3306 (default) for the SQL connection, just as you've done to your config.php file).
Done with everything? Start the server (I hate to tell you but you might have a bad time due to using windows, I mentioned 1000 times that people shouldn't use this cheap system to host servers, even for testing purposes...) go to the website, create an account and a player, open your client and log in.
Kindest Regards,
