+node-red-node-discover
+======================
+
+A Node-RED node that uses Bonjour
+ / Avahi to discover local network services such as iTunes libraries, printers, etc.
+
+Prerequisites
+-------------
+
+please read the [install instructions](https://www.npmjs.com/package/mdns) for the underlying npm.
+
+For Debian / Ubuntu this requires installing
+
+ sudo apt-get install libavahi-compat-libdnssd-dev
+
+Install
+-------
+
+Run the following command in the root directory of your Node-RED install
+
+ npm install node-red-node-discover
+
+Usage
+-----
+
+Uses a javascript implenetation of mdns ( mdns-js ) to provide a Bonjour / Avahi
+service discovery capability.
+
+**msg.payload** contains the service object on both arrival and leaving.
+
+**msg.state** contains boolean true or false depending if the service has arrived (true) or gone away (false)..
+
+Within the msg.payload object the most interesting things are:
+
+ * msg.payload.name
+ * msg.payload.interface
+ * msg.payload.port
+ * msg.payload.addresses
+ * msg.payload.txtRecord
+
+For a full list of official service types see [this list](http://www.dns-sd.org/ServiceTypes.html" target="_new).
+
+**Note**: When Node-RED starts you will get a big WARNING message about the Bonjour compatability layer... this is just a warning so don't worry.

+node-red-node-snmp
+==================
+
+A pair of Node-RED nodes that
+fetch either individual oids, or a table oid from a SNMP enabled host.
+
+Install
+-------
+
+Run the following command in the user directory of your Node-RED install.
+( typically ~/.node-red )
+
+ npm install node-red-node-snmp
+
+
+Usage
+-----
+
+###snmp
+
+SNMP oids fetcher. Can fetch a single or comma separated list of oids. Triggered by any input.
+
+**msg.oid** may contain a comma separated list of oids to search for. (no spaces)
+
+The oids confgured in the edit config will override msg.oid. Leave blank if you
+want to use msg.oid to provide input.
+
+Outputs **msg.payload** containing a table of objects. Values depends on the oids being requested.
+
+###snmp-table
+
+Simple SNMP table oid fetcher. Triggered by any input.
+
+**msg.oid** may contain the oid of a single table to search for.
+
+The oid confgured in the edit config will override msg.oid. Leave blank if you
+want to use msg.oid to provide input.
+
+Outputs **msg.payload** containing the table of objects. Values depends on the oids being requested.
