As I write and you read this, the WordPress core team is in the process of developing an entirely new content editor for WordPress – Gutenberg – and it is currently scheduled for release at some point in 2018 as part of WordPress 5.0.
When that happens, the way that you write your blog posts in WordPress will drastically change (though you will be able to install a plugin to keep using the current editor, if desired).
It is to help you get ready for the change that I have penned down this post on How To Use The WordPress Gutenberg Editor.
I’ll show you exactly how you can use the new editor to write a blog post so that you are ready for the transition when WordPress 5.0 and Gutenberg get released.
