First thing you need to do is install and activate the Polylang plugin. Upon activation, you need to visit Settings » Languages to configure the plugin.
The language settings page is divided into three tabs. The first tab is labeled‘Languages’. This is where you add the languages you want to use on your site.
You will need to add the default language, as well as select all other languages that users can choose on your site.
After adding the languages, switch to the ‘Strings Translations’ tab. Here you need to translate site title, description, and then choose the date and time format.
Last step in the configuration is the Settings tab. This is where you can choose a default language for your site and other technical settings.
Adding Multilingual Content in WordPress
Polylang makes it super easy to add content in different languages. Simply create a new post/page or edit an existing one. On the post edit screen, you will notice the languages meta box.
Your default language will automatically be selected, so you can first add content in your default language, and then translate it into others.
To translate, you need to click on the + button next to a language and then add content for that language.
