+# Setup the build
+First switch to this application directory:
 
 	cd RIOT/examples/rpl_udp
+
+#### Parameterizing the build
+The build system provides two specific parameters for the RPL module.  
+These parameters are:
+ * `RPL_MAX_ROUTING_ENTRIES` sets the desired maximum number of entries for the RPL routing table. _If this parameter is not provided, a [default](https://github.com/RIOT-OS/RIOT/blob/master/sys/net/include/rpl/rpl_config.h#L130) value is used._
+ * `RPL_NODE_IS_ROOT` indicating the build is specifically for a root node. This parameter is **only required** for using [`RPL_NON_STORING_MODE`](https://github.com/RIOT-OS/RIOT/blob/master/sys/net/include/rpl/rpl_config.h#L31) MOP to initialize a RPL routing table. The parameter is ignored in all other cases. _For non-storing MOP a node does not require to provide a routing table._
+
+#### Compiling the executable
+**example for [`RPL_STORING_MODE_NO_MC`](https://github.com/RIOT-OS/RIOT/blob/master/sys/net/include/rpl/rpl_config.h#L139):**
+
 	make

+builds the project and creates `128` entries for the RPL routing table by default.
+
+	make RPL_MAX_ROUTING_ENTRIES=103
+
+builds the project and creates `103` entries for the RPL routing table **overwriting** the default value.
+
+**example for [`RPL_NON_STORING_MODE`](https://github.com/RIOT-OS/RIOT/blob/master/sys/net/include/rpl/rpl_config.h#L133):**
+
+	make RPL_MAX_ROUTING_ENTRIES=103 RPL_NODE_IS_ROOT=1
+
+builds the project and creates `103` entries for the RPL routing table for the root node.
+
+#### _[native only]_ Set up a bridge for *two* tap devices for communication
 
 	../../cpu/native/tapsetup.sh create 2
 
-# rpl init
+The `2` corresponds to the number of _virtual_ nodes to be started.  
+The tap devices are bound to the _virtual_ native node on starting the created executable `rpl_udp.elf`.  
 
+#### _[native only]_ Starting _virtual_ nodes
 Run the first node
 
 	make term
 
+This starts the executable binding a _virtual_ node to the first tap device `tap0`.  
+
+**Further nodes must be bound to tap devices manually.**  
+For the second node it would be:
+
+	make term PORT=tap1
+
+
+# RPL init
