The plugin automatically adjusts the HTML lang attribute and adding hreflang tags for better SEO and user experience.

Define the language “folder” page and specify the number of pages your website will have (up to four in the Lite version).</li>

To improve your SEO and the accessibility of your content, you must declare changes of language within your content. 
You must also declare translations of your pages to Google to avoid duplicate content.
TinyMCE: For the people still in this old editor, buttons are available to add <code>lang</code> and <code>hreflang</code> attributes on your content, therefore to improve accessibility when screen readers are reading words from different languages than your main page language.
Gutenberg: For Gutenberg users, WordPress already provide the “Language” menu. When selecting a text you can add a specific language. This plugin will enhance this behaviour with its own command, and by remembering the last language code you used. 
This plugin also comes with a hreflang option that you can put on links to tell users “this link lead to a French website” for example.
Example of cases you need this plugin:
<ul>
<li>You translated a blog post in your language from another blog, (hreflang alternate links)</li>
<li>You publish the same article in 2 languages on 2 different websites, (hreflang alternate links)</li>
<li>You use in your content a jargon from another language. (<code>lang</code> attribute)</li>
<li>You link from your post other posts in another language. (<code>hreflang</code> attribute)</li>
<li>Your Menus have some items not translated (<code>lang</code> attributes) or lead to page in another language (<code>hreflang</code>), you can edit those attributes in the Menus admin-menu. (WordPress 5.4 compatibility) If you have a FSE (Full Site Editing) theme, I don’t know how this will work for you, but you can use the Gutenberg commands this plugin put at your disposal.</li>
</ul>
<h3>Features available</h3>
<ul>
<li>Custom <code>hreflang</code> alternate links for posts (page, and custom posts)</li>
<li>Attributes <code>hreflang</code> and <code>lang</code> available and visible in the editor</li>
<li>Attributes <code>hreflang</code> and <code>lang</code> available on your main Menus items. (WordPress 5.4 compatibility)</li>
</ul>
<h3>Known bugs</h3>
In old version of Gutenberg, the <code>hreflang</code> attribute on links is applied, but never save it in database. That is because <code>hreflang</code> is cleaned from WordPress posts. Indeed, it was not well recognized by the WordPress post sanitizing function.
