+# Development / test scripts
+
+## `setup_network.sh`
+
+`setup_network.sh` is used as-is, and as_root :-/
+This little thing adds some LINUX network namespaces in which you can run mycelium 
+U're a dev so deal with it
+
+
+## testing mycelium (`bigmush.sh`)
+This lill skrip will just start $NUMOFNS network namespaces in your LINUX box where you can SUDO (because I __know__ for a fact that you weren't root, of course), start a mycelium daemon in the main namespace and one in each NS.
+
+### Usage :
+
+Start with 
+```bash
+source ./bigmush.sh
+getmycelium
+```
+will get the latest __release__ binary from github
+
+Then
+```bash
+source ./bigmush.sh
+doit
+```
+
+will create and start a 50 node mycelium with one central
+
+```bash
+source ./bigmush
+dropit
+```
+will kill with little mercy mycelium daemons and delete the namespaces
+
+
+```bash
+source ./bigmush.sh
+cleanit
+```
+will do a `dropit` and clean `*.{bin,out}` files
+
+```bash
+showit
+```
+
+will send a USR1 signal to all mycelium daemons that will
+  - send routing tables and peers to stdout
+  - where stdout will be captured in `xx.out` for each NS
+
+### logging
+every namespace has an `xx.out` file that is stout and stderr
+the `xx.bin` file is the namespace daemon's privkey.
+
+### behaviour testing
+
+1) verify if you can reach all mycelium namespaces
+2) also when running another machine in your net, verify if it's automatically detected
