Embedding Discord Widget to a WordPress Website

First of all, create a Discord user account and a Discord server.

Go to the Discord website. Login if you have a Discord account or click Open Discord in your browser. Fill in your information and create a Discord server. This option will be proposed to you during the process of registration. Verify your account via email.

Then click an arrow button on the right of your server name to open a dropdown menu. Select Server Settings > Widget. Click Enable Server Widget, scroll down and copy the embed code from a Premade Widget section.

Open your WordPress web-page (that you want to embed a Discord Widget to) for editing, paste the embed code to the Custom HTML block, click Publish or Update to save the changes.
