 ========================
 Internet of Things (IoT)
 ========================
 
+Odoo Internet of Things (IoT) allows to connect physical devices such as barcode scanners, receipt
+printers, payment terminals, measurement tools, etc. to an Odoo database using an IoT system.
+
+The following IoT systems are supported:
+
+- :doc:`IoT box <iot/iot_box>`: micro-computer, plug-and-play device (i.e., the Odoo IoT program is
+  pre-installed);
+- :doc:`Windows virtual IoT <iot/windows_iot>`: Odoo IoT program for Windows that can be installed
+  on a Windows computer.
+
+.. note::
+   - :abbr:`MRP (Material Requirement Planning)` devices, including cameras and measurement tools,
+     are not compatible with Windows virtual IoT.
+   - Multiple IoT systems can be used at the same time.
+   - It is also possible to create a Windows Virtual Machine on a MacOS/Linux computer. However,
+     this option is not supported by Odoo, and no troubleshooting assistance will be provided.
+
+.. _iot/iot/iot-subscription:
+
+IoT box subscription
+====================
+
+An IoT box subscription is required for production use of IoT systems. If you have issues related
+to your subscription, contact the database's account manager or Odoo partner for assistance.
+
+.. tip::
+   If the subscription is linked to an `Odoo.com <https://www.odoo.com>`_ portal user, check the
+   information on the portal's subscription page.
