How to make an Apache server public from my own computer IP address?

I've looked everywhere, and have tried many solutions, but have not been able to find the answer to this question.

When I run localhost, I am able to access the default config file in Apache, because the Apache web server is running.

Now what I would like to do, is alter the default config, so that anyone can access the page publicly. I would like to do this with my public ip address, and am not concerned with security, I am more concerned about getting this to work.

What do I have to alter, to achieve this?

The following is my default config file, which is accessed in /etc/apache2/sites-available

<VirtualHost *:80>

#ServerName www.example.com

ServerAdmin webmaster@localhost

DocumentRoot /var/www/html


ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined


</VirtualHost>
