 Overview of SO Actor
-#############################
+######################
+ONAP Policy Framework enables SO as one of the supported actors.  SO uses a REST-based
+interface.  However, as requests may not complete right away, a REST-based polling
+interface is used to check the status of the request.  The *requestId* is extracted
+from the initial response and is appended to the *pathGet* configuration parameter to
+generate the URL used to poll for completion.
+
+Each operation supported by the actor is associated with its own java class, which is
+responsible for populating the request structure appropriately and sending the request.
+Note: the request may be issued via POST, DELETE, etc., depending on the operation.
+The operation-specific classes are all derived from the *SoOperation* class, which is,
+itself, derived from *HttpOperation*.  The following operations are currently supported:
+
+- VF Module Create
+- VF Module Delete
+
+
+Request
+#######
+
+A number of nested structures are populated within the request.  Several of them are
+populated with data extracted from the A&AI Custom Query response that is retrieved
+using the Target resource ID specified in the *ControlLoopOperationParams*.  The
+following table lists the contents of some of the fields that appear within these
+structures.

+Configuration of the SO Actor

+=============================== ====================    ==================================================================
+clientName                        string                  Name of the HTTP client to use to send the request to the
+                                                          SO REST server.
+timeoutSec                        integer (optional)      Maximum time, in seconds, to wait for a response to be received
+                                                          from the REST server.  Defaults to 90s.
+path                              string                  URI appended to the URL.  This field only applies to individual
+                                                          operations; it does not apply at the actor level.  Note: the
+                                                          *path* should not include a leading or trailing slash.
+maxGets                           integer (optional)      Maximum number of get/poll requests to make to determine the
+                                                          final outcome of the request.  Defaults to 20.
+waitSecGet                        integer (optional)      Time, in seconds, to wait between issuing "get" requests.
+                                                          Defaults to 20s.
+pathGet                           string (optional)       Path to use when polling (i.e., issuing "get" requests).
+                                                          Note: this should include a trailing slash, but no leading
+                                                          slash.
+=============================== ====================    ==================================================================
 
-This is a place-holder for the actor documentation.
+The individual operations are configured using these same field names.  However, all
+of them, except the *path*, are optional, as they inherit their values from the
+corresponding actor-level fields.
