 -------------------------
 
 There are two types of enums. ``IntEnum`` is used for a discrete values
-and ``IntFlag`` is used for bit flags. For example, ``DeviceType`` identifies
-a single device type as a device cannot be of multiple types.
-``WifiCapabilities`` shows a particular Wifi device capabilities which it
-can have multiple, for example, supporting both 5GHz and 2.4GHz radio bands.
+and ``IntFlag`` is used for bit flags. For example, :py:class:`DeviceType <sdbus_async.networkmanager.enums.DeviceType>`
+identifies a single device type as a device cannot be of multiple types.
+:py:class:`WifiCapabilitiesFlags <sdbus_async.networkmanager.enums.WifiCapabilitiesFlags>`
+shows a particular Wifi device capabilities which it can have multiple, for example, supporting
+both 5GHz and 2.4GHz radio bands.
 
 Usually ``IntEnum`` is implied unless the enum's name ends with ``Flag``.
 
 Example code using enums:
 
 .. code-block:: python
 
-   from sdbus_async.networkmanager.enums import DeviceType, WifiCapabilities
+   from sdbus_async.networkmanager.enums import DeviceType, WifiCapabilitiesFlags
 
    # Get particular device type from an integer
    DeviceType(2) == DeviceType.WIFI
    # Returns: True
 
    # Check if a specific flag is enabled
-   WifiCapabilities.FREQ_2GHZ in WifiCapabilities(0x00000400 | 0x00000200)
+   WifiCapabilitiesFlags.FREQ_2GHZ in WifiCapabilitiesFlags(0x00000400 | 0x00000200)
    # Returns: True
 
    # Iterate over all enabled flags
-   list(WifiCapabilities(0x00000400 | 0x00000200))
-   # Returns: [<WifiCapabilities.FREQ_2GHZ: 512>, <WifiCapabilities.FREQ_5GHZ: 1024>]
+   list(WifiCapabilitiesFlags(0x00000400 | 0x00000200))
+   # Returns: [<WifiCapabilitiesFlags.FREQ_2GHZ: 512>, <WifiCapabilitiesFlags.FREQ_5GHZ: 1024>]
