- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control.
- Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities.
- Created .gitmodules to include OpenZeppelin contracts as a submodule.
- Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment.
- Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks.
- Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring.
- Created scripts for resource import and usage validation across non-US regions.
- Added tests for CCIP error handling and integration to ensure robust functionality.
- Included various new files and directories for the orchestration portal and deployment scripts.

+
+## Environment Variables
+
+Most scripts support the following environment variables:
+
+- `RESOURCE_GROUP` - Azure resource group name (default: `defi-oracle-mainnet-rg`)
+- `CLUSTER_NAME` - Cluster name (default: `defi-oracle-aks`)
+- `KEY_VAULT_NAME` - Key Vault name (default: `defi-oracle-kv`)
+- `VALIDATOR_COUNT` - Number of validators (default: `2`)
+- `SENTRY_COUNT` - Number of sentries (default: `2`)
+- `RPC_COUNT` - Number of RPC nodes (default: `2`)
+
+## Prerequisites
+
+- Azure CLI installed and configured
+- SSH key pair for VM access
+- Terraform >= 1.0 (for deployment scripts)
+- `jq` for JSON parsing
+- `curl` for HTTP requests
+
+## Examples
+
+### Deploy Network
+
+```bash
+export RESOURCE_GROUP="defi-oracle-mainnet-rg"
+export SSH_PUBLIC_KEY=$(cat ~/.ssh/id_rsa.pub)
+./scripts/vm-deployment/deploy-vm-network.sh
+```
+
+### Monitor Specific VM
+
+```bash
+export VM_IP="20.123.45.67"
+./scripts/vm-deployment/monitor-vm.sh
+```
+
+### Scale RPC VMSS
+
+```bash
+export RESOURCE_GROUP="defi-oracle-mainnet-rg"
+./scripts/vm-deployment/scale-vmss.sh besu-rpc-vmss 5
+```
