+# Modules
+
+A module is a field-replaceable hardware component installed within a device which houses its own child components. The most common example is a chassis-based router or switch.
+
+Similar to devices, modules are instantiated from module types, and any components associated with the module type are automatically instantiated on the new model. Each module must be installed within a module bay on a device, and each module bay may have only one module installed in it. A module may optionally be assigned a serial number and asset tag.

+## Module Bays
+
+Module bays represent a space or slot within a device in which a field-replaceable module may be installed. A common example is that of a chassis-based switch such as the Cisco Nexus 9000 or Juniper EX9200. Modules in turn hold additional components that become available to the parent device.

+# Module Types
+
+A module type represent a specific make and model of hardware component which is installable within a device and has its own child components. For example, consider a chassis-based switch or router with a number of field-replaceable line cards. Each line card has its own model number and includes a certain set of components such as interfaces. Each module type may have a manufacturer, model number, and part number assigned to it.
+
+Similar to device types, each module type can have any of the following component templates associated with it:
+
+* Interfaces
+* Console ports
+* Console server ports
+* Power ports
+* Power Outlets
+* Front pass-through ports
+* Rear pass-through ports
+
+Note that device bays and module bays may _not_ be added to modules.
+
+## Automatic Component Renaming
+
+When adding component templates to a module type, the string `{module}` can be used to reference the `position` field of the module bay into which an instance of the module type is being installed.
+
+For example, you can create a module type with interface templates named `Gi{module}/0/[1-48]`. When a new module of this type is "installed" to a module bay with a position of "3", NetBox will automatically name these interfaces `Gi3/0/[1-48]`.
+
+Automatic renaming is supported for all modular component types (those listed above).
