6. Clone and Build Allora Chain

git clone https://github.com/allora-network/allora-chain.git
cd allora-chain && make all
allorad version

7. Add Wallet Key to Allora Chain

allorad keys add "wallet_name" --recover

8. Clone Basic Coin Prediction Node Project and Create Data Directories

cd $HOME && git clone https://github.com/allora-network/basic-coin-prediction-node
cd basic-coin-prediction-node
mkdir worker-data
mkdir head-data

9. Set Permissions for Data Directories

sudo chmod -R 777 worker-data
sudo chmod -R 777 head-data

10. Generate Keys for Head Data

sudo docker run -it --entrypoint=bash -v ./head-data:/data alloranetwork/allora-inference-base:latest -c "mkdir -p /data/keys && (cd /data/keys && allora-keys)"

11. Generate Keys for Worker Data

sudo docker run -it --entrypoint=bash -v ./worker-data:/data alloranetwork/allora-inference-base:latest -c "mkdir -p /data/keys && (cd /data/keys && allora-keys)"

12. View Identity Key

cat head-data/keys/identity

13. Create and Edit docker-compose.yml

rm -rf docker-compose.yml && nano docker-compose.yml
