Building a page is not easy for people not familiar with the manual work of the webpage.
Even though I am a toddler in web design, I decided to develop my page by adding a subscription option.
Basically, subscription divides into free and paid subscriptions.
To proceed with your subscription tool, you need to install and activate the “subscription” application from Plugin.
“Plugins” is like an app store to interlock with various applications in WordPress.
Further, if you proceed paid subscription, you need to link and operate with “WooCommerce.”
For a detailed explanation, I recommend you to find the tutorial by typing “how to add subscribe option to your WordPress” on the search box on YouTube.
