Install the plugin named “Sirvoy Booking Engine” through the WordPress Admin Plugin Search. (Alternatively, download it from this link and upload it using the WordPress Admin Plugin Upload.)
In your Sirvoy account, go to Settings -> Booking engine -> Manage booking engines – > How to install and choose “Booking engine ID to be used in the WordPress plugin” and copy the code in the grey box.
Go back to WordPress and enter the booking engine ID in Settings -> Sirvoy Booking Engine.
Put this short code in the pages or posts where you want to display the booking engine: [sirvoy]
To display the booking engine in a specific language (not using auto-detect), use this format: [sirvoy language="fr"].
Optionally, go to Appearance -> Widgets in WordPress and add the “Sirvoy Hotel Booking Widget” to your sidebar.
