+Introduction:
+This tool is a plugin of Draw.io desktop application.
+It can automatically generate ACTN topology JSON data from graph.
+
+Installation and initialization:
+1) Extract the draw.io.7z file
+2) Run draw.io.exe in folder draw.io
+3) Click menu Extras->Plugins… 
+4) Import the plugin file named "ongen.js" 
+5) Click menu Extras->Load Default Settings
+
+Design ACTN multi-domain OTN topology and generate JSON data.
+1) Add network, node, port or link via drag-and-drop or copy-and-paste.
+2) Collapse or expand containers by shortcut "CTRL+J" and "CTRL+K"
+3) Assign the node id of all nodes automatically by clicking the menu Extras->'Auto-assign Node Id'
+4) Export to ACTN JSON data by clicking the menu Extras->'Export as ACTN JSON'.
