-# substrate-poc
-A new SRML-based Substrate node, ready for hacking
+# prototype-chain
 
-## Run inside docker container
+Substrate node implementation for the KILT prototype
+
+## Running a local node that connects to KILT prototype testnet in AWS
+
+There are master boot nodes running in the KILT testnet:
+
+* Alice (bootnode-alice.kilt-prototype.tk)
+* Bob (bootnode-bob.kilt-prototype.tk)
+
+To start a node and connect to Alice you can use the shell script `start-node.sh`:
+
+```
+./start-node.sh --account-name Charly --connect-to Alice
+``` 
+
+You can use any of the accounts declared in the chain spec to connect (Alice, Bob, Charly, Dave, Eve, Ferdie).
+
+Run `./start-node.sh --help` for more information.
+
+### Running a node inside a docker container
+
+Make sure to have the `awscli` installed. Otherwise Install it via `brew install awscli` (Mac).
+You also need to have your docker daemon system running (on mac, just download and install the docker application).
+
+Login to Amazon ECR
+
+```
+ $(aws ecr get-login --no-include-email --region eu-central-1)
+```
+
+Pull the latest image from Amazon ECR
 
 ```
-docker build -t substrate-poc . 
-docker run -p 9933:9933 -p 9944:9944 -p 30333:30333 --publish-all=true -it substrate-poc
+docker pull 348099934012.dkr.ecr.eu-central-1.amazonaws.com/kilt/prototype-chain:latest
 ```
+
+Run the image and pass the command to start a node
+
+```
+docker run 348099934012.dkr.ecr.eu-central-1.amazonaws.com/kilt/prototype-chain ./start-node.sh --account-name Charly --connect-to Alice
+```
+
+The node should be connected to the KILT testnet.
