+A simple tui to explore darkfi ircd network topology.
+
+dnetview displays: 
+
+1. all active nodes
+2. outgoing, incoming and manual sessions
+3. each associated connection and recent messages.
 
 dnetview is based on the design-pattern Model, View, Controller. We
 create a logical seperation between the underlying data structure or
 Model; the ui rendering aspect which is the View; and the Controller or
 game engine that makes everything run.
 
-## Version 0.1
-
-The current data structure or model of dnetview is this: 
-
-### Model
-```
-    Mutex<HashSet<NodeId>>
-    Mutex<HashMap<NodeId, NodeInfo>>
-```
-
-### View
-View is a copy of the model data with additional parameters. We remove
-the Mutex and add 'ListState' and 'Index' that allow us to use IdList
-and InfoList as lists.
-
-```
-    IdList {
-        ListState,
-        HashSet<NodeId>
-    }
-    InfoList {
-        Index,
-        HashMap<NodeId, NodeInfo>
-    }
-```
-
-### Controller
-
-Inside our main function we create two parallel threads: run_rpc and render.
-
-```
-Parallel::new() {
-    run_rpc(model)
-    render(model)
-}
+## install 
 
+```shell
+% git clone https://github.com/darkrenaissance/darkfi 
+% cd darkfi
+% make BINS=dnetview
 ```
 
-run_rpc polls the rpc every 2 seconds. This function updates the
-underlying model which is protected by mutexes, and detaches in the
-background.
+## usage
 
-render takes the latest model data and updates the view in a loop.
+Run dnetview as follows:
 
+```shell
+dnetview -v
 ```
-loop {
-    view = model.update()
-    }
-```
-
-## Version 0.2:
-
-In the first version, we could scroll the list of connected nodes and
-also scroll a corresponding list of NodeInfo. In the lastest version,
-the model is made more generic to allow for many types of selectable
-objects: NodeInfo, SessionInfo, and ConnectInfo.
 
-### Model
+On first run, dnetview will create a config file in .config/darkfi. You
+must manually enter the RPC ports of the nodes you want to connect to
+and title them as you see fit.
 
-The model has 3 types of SelectableObjects which are organized around
-an enum:
+Dnetview creates a logging file in /tmp/dnetview.log. To see json data
+and other debug info, tail the file like so:
 
-```
-enum SelectableObject {
-    Node(NodeId)
-    Session(SessionId)
-    Connect(ConnectId)
-}
-```
-Id is a randomly generated number to correspond to the received info.
-
-We copy all of these values into a info hashmap.
-
-```
-infos = Mutex<Hashmap<u32, SelectableObject>>
-```
-
-We use mutexes to protect the data because we are updating it
-asynchronously.
-
-### View
-
-View is a copy of model without mutex's and with an index that allows the
-objects to be scrollable lists.
-
-We create a IdsList which is a hashset of all the IDs and a ListState.
-This allows us to transform SelectableObject's into a scrollable list.
-
-```
-IdsList = HashSet<Id, ListState>
-```
-
-We also create a function called render() that draws each window.
-
-```
-NodeInfo.render()
-SessionInfo.render()
-ConnectInfo.render()
-```
-
-### Controller
-
-Like the previous version, we have two functions that run in parallel:
-run_rpc() and render().  In run_rpc, we poll the rpc and write the new
-values to the model:
-
-
-```
-    info = NodeInfo::new()...
-    session = SessionInfo::new()...
-    connection = ConnectInfo::new()...
-    model_vec.push(info, session, connection)
-```
-
-We then continuously update the view with the new data from the model.
-
-```
-loop {
-    view = model.update()
-}
+```shell
+tail -f /tmp/dnetview.log
 ```
