+# README
+`micro-daemon` is a respond daemon to fetch information for Freifunk Nodes
+and represent this information with Websocket- and JSON-APIs.
+
+## Issues/Features in the Future
+It will also APIs for manipulate the fetched data
+ and give a access for ansible to push changes to the nodes.
+
+Also it's will push statistic informations to a influxdb.
+
+## Usage
+```
+Usage of ./micro-daemon:
+  -aliases string
+    	path aliases.json file (default "webroot/aliases.json")
+  -collectInterval int
+    	interval for data collections (default 15)
+  -h string
+    	path aliases.json file
+  -output string
+    	path nodes.json file (default "webroot/nodes.json")
+  -p string
+    	path aliases.json file (default "8080")
+  -saveInterval int
+    	interval for data saving (default 60)
+```
+## Development
+### respond
+It send the `gluon-neighbour-info` request and collect them together.
+
+It will send UDP packetes by the multicast group `ff02:0:0:0:0:0:2:1001` and port `1001`.
+
+### modes.Nodes
+It cached the Informations of the Nodes and will save them periodical to a JSON file.
+The current nodes are saved default under `nodes.json`.
+
+
+### websocketserver
+One Instance is running under `/nodes` which send updates or new Nodes,
+ which are collected by respond.
+
+### Issues
+Later there should be also `/aliases` Websocket with Authentification to manage the `aliases.json` with the request for changes.
+
+A Implementation of the connection to influxdb are also needed, maybe log a little bit to `telegraf` from influxdb.
