# Verify Prerequisites Before Starting
**Verify Tool Installation**
After installing each tool (covered in [Azure Infrastructure Setup and CLI Configuration](https://docs.hivel.ai/self-managed-hivel-deployment/virtual-private-cloud/azure/hivel-on-premises-deployment-guide-azure/azure-infrastructure-setup-and-cli-configuration)), run these commands once to confirm you're on a supported version:
```
docker --version # supported: Docker >= 26.0
docker-compose --version # supported: Docker Compose >= 2.25.0
az --version # any current Azure CLI 2.x
aws --version # any current AWS CLI v2.x
psql --version # client only - server is Azure-managed, see Database Setup
df -h # confirm free disk space meets the specs in Virtual Machine Requirements
```
**Expected Result:** Each command prints a version string with no errors.
**If a Command Fails:** If you see "command not found," the tool is either not installed or not on your PATH. Go to [Azure Infrastructure Setup and CLI Configuration](https://docs.hivel.ai/self-managed-hivel-deployment/virtual-private-cloud/azure/hivel-on-premises-deployment-guide-azure/azure-infrastructure-setup-and-cli-configuration) and complete the installation steps for that tool.
