+# Fabric deployment notes
+
+## General notes
+Current Fabric deployment uses Fabric test network with some additional helping scripts on top of it.
+This deployment is highly insecure and *shouldn't be used in production* in any case.
+To start the network just run the `raft.sh` from `blockchain/scripts` directory. Use `stop.sh`
+when you need to stop the network.
+
+## Server start preparations
+To run the server it's necessary to copy certificate file
+`fabric-samples/test-network/organizations/peerOrganizations/org1.example.com/ca/ca.org1.example.com-cert.pem`
+to the config folder (replacing the existing one). Also it's necessary to copy `scripts/connection-org1.json`
+file (again, replacing the old one). After copying, it must be edited. First, all `localhost` entrances
+should be replaced with `teraflow.nlehd.de`. Second, `channel` section at the end of the file should be removed.
+This should be done after every restart of the Fabric network.
