+## Infrastructure as Code (IaC)
+
+Prowler's Infrastructure as Code (IaC) provider enables you to scan local infrastructure code for security and compliance issues using [Checkov](https://www.checkov.io/). This provider supports a wide range of IaC frameworks and requires no cloud authentication.
+
+### Authentication
+
+The IaC provider does not require any authentication or credentials since it scans local files directly. This makes it ideal for CI/CD pipelines and local development environments.
+
+### Supported Frameworks
+
+The IaC provider leverages Checkov to support multiple frameworks, including:
+
+- Terraform
+- CloudFormation
+- Kubernetes
+- ARM (Azure Resource Manager)
+- Serverless
+- Dockerfile
+- YAML/JSON (generic IaC)
+- Bicep
+- Helm
+- GitHub Actions, GitLab CI, Bitbucket Pipelines, Azure Pipelines, CircleCI, Argo Workflows
+- Ansible
+- Kustomize
+- OpenAPI
+- SAST, SCA (Software Composition Analysis)
+
+### Usage
+
+To run Prowler with the IaC provider, use the `iac` flag. You can specify the directory to scan, frameworks to include, and paths to exclude.
+
+#### Basic Example
+
+```console
+prowler iac --scan-path ./my-iac-directory
+```
+
+#### Specify Frameworks
+
+Scan only Terraform and Kubernetes files:
+
+```console
+prowler iac --scan-path ./my-iac-directory --frameworks terraform kubernetes
+```
+
+#### Exclude Paths
+
+```console
+prowler iac --scan-path ./my-iac-directory --exclude-path ./my-iac-directory/test,./my-iac-directory/examples
+```
