-#Ipfs Testbed
+# IPTB
+iptb is a program used to manage a cluster of ipfs nodes locally on your
+computer. It allows the creation of up to 1000 (limited by poor port choice)
+nodes, and allows for various other setup options to be selected such as
+different bootstrapping patterns. iptb makes testing networks in ipfs
+easy!
 
-##commands:
+### Commands:
+- init
+	- creates and initializes 'n' repos
+	- Options:
+		- -n=[number of nodes]
+		- -f : force overwriting of existing nodes
+		- -bootstrap : select bootstrapping style for cluster choices: star, none
+- start
+	- starts up all testbed nodes
+	- Options:
+		- -wait : wait until daemons are fully initialized
+- stop
+	- kills all testbed nodes
+- restart
+	- kills and then restarts all testbed nodes
 
-### init -n=[number of nodes]
-creates and initializes 'n' repos
+- shell [n]
+	- execs your shell with environment variables set as follows:
+	    - IPFS_PATH - set to testbed node n's IPFS_PATH
+	    - NODE[x] - set to the peer ID of node x
 
-### start 
-starts up all testbed nodes
+### Configuration
+By default, iptb uses `$HOME/testbed` to store created nodes. This path is
+configurable via the environment variables `IPTB_ROOT`.
 
-### stop 
-kills all testbed nodes
 
-### restart
-kills, then restarts all testbed nodes
 
-### shell [n]
-execs your shell with environment variables set as follows:
-- IPFS_PATH - set to testbed node n's IPFS_PATH
-- NODE[x] - set to the peer ID of node x
