 The General Modeling Network Specification (GMNS) defines a common human and machine readable format for sharing routable road network files.  It is designed to be used in multi-modal static and dynamic transportation planning and operations models.  
 
 How do I use GMNS?
-1.  Read the [__specification reference__](../../wiki) to learn about the GMNS format.
+1.  Read the [__specification reference__](Specification) to learn about the GMNS format.
 2.	Look at our [__small examples__](Small_Network_Examples), including a freeway interchange, a portion of a multimodal city network, and a small city.
 3.	Build and test your own small network. We have basic tools in Python and R for [__conversion__](Conversion_Tools) and [__validation__](Validation_Tools).  
 
+**Note**: Some of the examples, and all of the conversion and validation tools, have not yet been updated to reflect the latest changes to the specification. These are indicated by the following sign :warning: in their respective readme files.

 ## GMNS Overview
-Version 0.80 includes the following features for use in static models:
+Version 0.85 includes the following features for use in static models:
 -	Configuration information and use definitions.
--	Node and road_link files, to establish a routable directed network.
--	A link_geometry file containing the geometry and physical characteristics of links.
+-	Node and link files, to establish a routable network. 
 
 For dynamic models, this version includes the following optional additional features:
--	An offroad_link file, for building undirected routable networks (like sidewalks)
--	A segment file, with information that overrides the characteristics of a portion of a road_link.  
+-	A segment file, with information that overrides the characteristics of a portion of a link.  
 -	A lane file that allocates portions of the right-of-way. Lanes include travel lanes used by motor vehicles. They may also optionally include bike lanes, parking lanes, and shoulders. 
--	A location file, that specifies points along a link (e.g., driveways or GTFS bus stops)
--	A link_TOD file, that allocates usage of links (or lanes) by time-of-day and day-of-week.  
--	Movement and Movement_TOD files that specifies how inbound and outbound lanes connect at an intersection, and time/day restrictions on those movements. 
+-	A segment_lane file that specifies additional lanes, dropped lanes, or changes to lane properties on a segment of a link.
+-	A movement file that specifies how inbound and outbound lanes connect at an intersection
+-	Link, segment, lane and movement time-of-day (TOD) files, that allocates usage of network elements by time-of-day and day-of-week. 
 -	Signal phase and timing files, for basic implementation of traffic signals.

+# Broadway at Ames Street, Cambridge, MA
+
+This example shows the proposed GMNS v0.85 specification around one
+intersection in Cambridge, MA, down the street from the Volpe Center.
+
+There are many interesting features nearby, including:
+
+  - A bike path and pedestrian walkway, to the west of Volpe
+
+  - A mid-block crossing on Broadway, in front of Volpe
+
+  - A floating bus stop and cycletrack on Ames Street
+
+The QGZ file in this folder can be used for visualizing the network; you
+may need to change the filepaths to where GitHub is located on your
+machine.
