 <h2>DESCRIPTION</h2>
 
- at TODO
+<em>Vector Network Analysis Tool</em> is graphical front-end for <tt>v.net*</tt> modules. It allows perform network analysis directly in <em><a href=http://grass.fbk.eu/gdp/html_grass70/wxGUI.html>wxGUI</a></em> without need to use command line. The tool is available from GRASS AddOns repository and needs to be installed to GRASS GIS by command:
+<p> 
+<tt>g.extension -s extension=wx.vnet</tt>
+<p>
+ The tool can be launched from Map Display toolbar submenu of <tt>Analyze Map</tt> button where is <tt>Vector network analysis (experimental, GSoC 2012)</tt> item. 
 
+<p>
+<em>Vector Network Analysis Tool</em> currently allows to:
+
+<ul>
+  <li> perform these network analyses:</li>
+  <ul>
+    <li> Shortest path (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.path.html">v.net.path</a></em>)</li>
+    <li> Salesman (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.salesman.html">v.net.salesman</a></em>)</li>
+    <li> Flow (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.flow.html">v.net.flow</a></em>)</li>
+    <li> Allocate subnets for nearest centers (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.alloc.html">v.net.alloc</a></em>)</li>
+    <li> Steiner tree for the network and given terminals (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.steiner.html">v.net.steiner</a></em>)</li>
+    <li> Find shortest distance via the network (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.distance.html">v.net.distance</a></em>)</li>
+    <li> Splits net by cost isolines (<em><a href="http://grass.fbk.eu/gdp/html_grass70/v.net.iso.html">v.net.iso</a></em>)</li>
+  </ul>
+  <li>show and set all data needed for the analysis (points, attribute tables, compute costs)</li>
+  <li>show analysis results (maps and it's attribute tables)</li>
+  <li>snapping to nodes</li>
+  <li>browse previous analysis results</li>
+</ul>
+
+<h4>TABS</h4>
+The tool is split into tabs. Every Tab represents some functionality:
+
+<ul>
+  <li> <tt>Parameters</tt> tab - It is used for setting vector map and it's layer on which analysis will be done. Also it is possible to set cost values from attribute table connected to particular layer.</li>
+  <li> <tt>Points</tt> tab - It manages points, which are used for analysis.</li>
+  <li> <tt>Output</tt> tab - There is output console, which shows report during analysis. </li>
+  <li> <tt>Input tables</tt> tab - When existing vector map and it's existing layers are set in <tt>Parameters</tt> tab, this tab is dynamically added. It shows attribute tables of node and arc layers, which were chosen for analysis. It is also possible to compute cost values in this tab. This can be done by right mouse button click on column label. Then from pop-up menu choose <tt>Add column</tt>, where new column for cost values can be created. After that  by right mouse button click on the added column label can be chosen item <tt>Field calculator</tt>. This tool allows to compute cost values.</li>
+  <li> <tt>Result tables</tt> tab - Result of vector network analysis is always vector map. Some vector network analysis results can also include attribute tables. If such a table is connected to result map, this tab is showed and allows to browse these data.</li>
+</ul>
+
+<h2>KNOWN ISSUES</h2>
+When some change is done in layer tree of Map Display, temporary vector map representing result of analysis is not rendered anymore.
