See `examples/example-certificates.hcl` for a more advanced provisioning file with templates and variables.
## Building the Tool
The repository includes a `build.sh` script to build the CLI tool. It updates the version in `version.go` and builds the binary.
To ignore changes made to `version.go` in Git, you can run:
```bash
git update-index --assume-unchanged version.go
