+= Integration tests for eth protocol and blockpool 
+
+This is a simple suite of tests to fire up a local test node with peers to test blockchain synchronisation and download. 
+The scripts call ethereum (assumed to be compiled in go-ethereum root). 
+
+To run a test:
+
+    . run.sh 00 02
+
+Without arguments, all tests are run. 
+
+Peers are launched with preloaded imported chains. In order to prevent them from synchronizing with each other they are set with `-dial=false` and `-maxpeer 1` options. They log into `/tmp/eth.test/nodes/XX` where XX is the last two digits of their port. 
+
+Chains to import can be bootstrapped by letting nodes mine for some time. This is done with 
+
+    . bootstrap.sh 
+
+Only the relative timing and forks matter so they should work if the bootstrap script is rerun. 
+The reference blockchain of tests are soft links to these import chains and check at the end of a test run. 
+
+Connecting to peers and exporting blockchain is scripted with JS files executed by the JSRE, see `tests/XX.sh`. 
+
+Each test is set with a timeout. This may vary on different computers so adjust sensibly. 
+If you kill a test before it completes, do not forget to kill all the background processes, since they will impact the result. Use:
+
+    killall ethereum
