WordPress Multisite allows users to have multiple sites in a single installation of the WordPress application. The multisite network owner can manage multiple sites from the same WordPress admin panel, including the number of sites, what themes and plugins are active for different websites, users, and website features separately.

WordPress Multisite is best used when you are creating a network of websites that share similar aspects and functionality. This is because all plugins and themes are shared between websites and you can configure everything globally for all websites at the same time. If you plan to have websites with different themes or allow users to manage the theme and plugins of their own websites, WordPress Multisite is not recommended.

Most WordPress themes take the subtitle text from your blog tagline. To edit it, access your WordPress admin panel, go to Settings > General and change the value of the Short Description field.

Please note that advanced WordPress themes may have custom settings pages where you can change these settings.

Once you have installed WordPress, you can start building your blog. First, navigate to the WP login page by entering the admin login URL: www.yourdomain.com/wp-login.php. Make sure you replace yourdomain.com with your actual domain.

There you should enter your access data, the ones you chose during the installation process. You will then be taken to the WordPress administration area.

To start writing posts on your WordPress blog, click Posts > Add New from your desktop. You will be redirected to a page where you can create your new item. Click Publish once it's ready and your post will be immediately visible on your blog's main page.

RSS stands for Really Simple Syndication – a web feed format that publishes frequent updates to your site's content such as news, articles, etc.

Publishers benefit from RSS feeds as this allows them to distribute site content automatically. Readers benefit from feeds by getting timely updates when something new is published on their favorite websites.

WordPress gives you the option to easily add an RSS feed to your website. To do so, follow these steps:

• Access your WordPress dashboard and go to Widgets in the Appearance section.
• Click Add next to the RSS widget.
• In the Current Widgets section on the right, click Edit for the RSS widget.
• Add the RSS feed URL (title is optional) and review the content you want to display.
• Click Done and then save the changes to publish the RSS to the website.
