The Gutenberg plugin is now part of the WordPress core, so it is not necessary to install it separately. However, if you are using an older version of WordPress and want to install the Gutenberg plugin, you can follow these steps:
Log in to your WordPress website.
In the WordPress dashboard, click on "Plugins" in the left-hand menu.
Click on "Add New" button.
In the search bar, type "Gutenberg" and hit enter.
Find the Gutenberg plugin and click on "Install Now" button.
Once the plugin is installed, click on "Activate" button.
The Gutenberg plugin is now installed and activated on your WordPress website.
That's it! You have now successfully installed the Gutenberg plugin on your WordPress website. With Gutenberg, you can create and edit content using a block-based editor that makes it easy to customize your pages and posts.
