 WPS needs the Universally Unique IDentifier (UUID; see RFC 4122) for
 the device. This is configured in the runtime configuration for
-wpa_supplicant:
+wpa_supplicant (if not set, UUID will be generated based on local MAC
+address):
 
 # example UUID for WPS
 uuid=12345678-9abc-def0-1234-56789abcdef0

+Scanning
+--------
+
+Scan results ('wpa_cli scan_results' or 'wpa_cli bss <idx>') include a
+flags field that is used to indicate whether the BSS support WPS. If
+the AP support WPS, but has not recently activated a Registrar, [WPS]
+flag will be included. If PIN method has been recently selected,
+[WPS-PIN] is shown instead. Similarly, [WPS-PBC] is shown if PBC mode
+is in progress. GUI programs can use these as triggers for suggesting
+a guided WPS configuration to the user. In addition, control interface
+monitor events WPS-AP-AVAILABLE{,-PBC,-PIN} can be used to find out if
+there are WPS enabled APs in scan results without having to go through
+all the details in the GUI. These notification could be used, e.g., to
+suggest possible WPS connection to the user.
+
+
+wpa_gui
+-------
+
+wpa_gui-qt4 directory contains a sample GUI that shows an example of
+how WPS support can be integrated into the GUI. Its main window has a
+WPS tab that guides user through WPS registration with automatic AP
+selection. In addition, it shows how WPS can be started manually by
+selecting an AP from scan results.
+
+
+Credential processing
+---------------------
+
+By default, wpa_supplicant processes received credentials and updates
+its configuration internally. However, it is possible to
+control these operations from external programs, if desired.
+
+This internal processing can be disabled with wps_cred_processing=1
+option. When this is used, an external program is responsible for
+processing the credential attributes and updating wpa_supplicant
+configuration based on them.
+
+Following control interface messages are sent out for external programs:
+
+WPS-CRED-RECEIVED  <hexdump of Credential attribute(s)>
+For example:
+<2>WPS-CRED-RECEIVED 100e006f10260001011045000c6a6b6d2d7770732d74657374100300020020100f000200081027004030653462303435366332363666653064333961643135353461316634626637313234333761636664623766333939653534663166316230323061643434386235102000060266a0ee1727
