 Similar to the JSON sibling directory that provides Perl JSON adapters
 with the LANforge client, this directory provides Python adapters to
-the LANforge client. The LANforge client is the LANforge Java GUI 
+the LANforge client. The LANforge client is the LANforge Java GUI
 package running with the `-http` switch (by default) and possibly in the *headless*
 mode using the `-daemon` switch.

+Follow our [getting started cookbook](http://www.candelatech.com/cookbook.php?vol=cli&book=Querying+the+LANforge+GUI+for+JSON+Data)
 to learn more about how to operate your LANforge client.
 
+## Getting Started ##
+New automation tests and JSON client scripts should go in `../py-scripts`. This directory
+is intended for utility and library scripts. To use this module, make sure your include path
+captures this module by adding it to your `sys.path`. We recommend your scripts in `../py-scripts`
+begin with these imports:
+
+    `if 'py-json' not in sys.path:
+        sys.path.append('../py-json')
+    from LANforge import LFUtils
+    from LANforge import lfcli_base
+    from LANforge.lfcli_base import LFCliBase
+    from LANforge.LFUtils import *
+    import realm
+    from realm import Realm
+
+
 ## These Scripts ##
 
-  * `show_ports.py`: this simple example shows how to gather a digest of ports
+  * `__init__.py`: this is a module header and it defines its relationship to sub-module LANforge,
+                   requiring LFRequest.
+  * `LANforge`: this module is for our json library. Use gain access to these by using:
+                `import LANforge`
+                `from LANforge import LFUtils`
+                `from LANforge import LFRequest`
   * `create_sta.py`: Please follow though `create_sta.py` to see how you can
                      utilize the JSON API provided by the LANforge client. It
                      is possible to use similar commands to create virtual Access points.
+  * `create_wanlink.py`: example that creates a WANlink
+  * `generic_cx.py`: example that creates a cross connect
+  * `realm.py`: module defining the Realm class. `Realm` is a toolbox class that also serves as a facade
+                for finer-grained methods in LFUtils and LFRequest:
+    * `__init__`: our constructor
+    * `load()`: load a test scenario database, as you would find in the GUI Status tab
+    * `cx_list()`: request json list of cross connects
+    * `station_map()`: request a map of stations via `/port/list` and alter the list to name based map of only stations
+    * `station_list()`: request a list of stations
+    * `vap_list()`: request a list of virtual APs
+    * `remove_vlan_by_eid()`: a way of deleting a port/station/vAP
+    * `find_ports_like()`: returns a list of ports matching a string prefix, like:
+      * `sta\*` matches names starting with `sta`
+      * `sta10+` matches names with port numbers 10 or greater
+      * `sta[10..20]` matches a range of stations including the range sta10 -- sta20
+    * `name_to_eid()`: takes a name like `1.1.eth1` and returns it split into an array `[1, 1, "eth1"]`
+    * `parse_time()`: returns numeric seconds when given strings like `1d`, `2h`, or `3m` or `4s`
+    * `parse_link()`:
+    * `new_station_profile()`: creates a blank station profile, configure station properties in this profile
+                               and then use its `create()` method to create a series of stations
+    * `new_l3_cx_profile()`: creates a blank Layer-3 profile, configure this connection profile and
+                             then use its `create()` method to create a series of endpoints and cross connects
+    * `new_l4_cx_profile()`: creates a blank Layer-4 (http/ftp) profile, configure it then call `create()`
+    * `new_generic_cx_profile()`: creates a blank Generic connection profile (for lfping/iperf3/curl-post/speedtest.net)
+                                  then configure and call `create()`
+    * `class L3CXProfile`: this class is the Layer-3 connection profile
+      * `__init__`: should be called by `Realm::new_l3_cx_profile()`
+      * `create()`: pass endpoint-type, side-a list, side-b list, and sleep_time between creating endpoints and connections
+      * Parameters for this profile include:
+        * prefix
+        * txbps
+    * `class L4CXProfile`: this class is the Layer-4 connection profile
+      * `__init__`: should be called by `Realm::new_l4_cx_profile()`
+      * `create()`: pass a list of ports to create endpoints on, note that resulting cross connects are prefixed with `CX_`
+      * Parameters for this profile include:
+        * url
+        * requests_per_ten: number of requests to make in ten minutes
+        *
+  * `show_ports.py`: this simple example shows how to gather a digest of ports
