-# SAST (Static Application Security Testing)
 
-Read more about this feature here: https://docs.gitlab.com/ee/user/application_security/sast/
+This project provides components for the use of Static Application Security Testing as well as Infrastructure as Code scanning. 
 
-Configure SAST with CI/CD variables (https://docs.gitlab.com/ee/ci/variables/index.html).
-List of available variables: https://docs.gitlab.com/ee/user/application_security/sast/index.html#available-cicd-variables

-## Usage
+## Static Application Security Testing (SAST)
+
+### Documentation References
+
+Configuration for SAST can be performed through [CI/CD Variables](https://docs.gitlab.com/ee/ci/variables/index.html) or via the definition of [Inputs](https://docs.gitlab.com/ci/inputs/). 
+
+More information about GitLab SAST is available within [GitLab documentation](https://docs.gitlab.com/ee/user/application_security/sast/), along with the [available variables](https://docs.gitlab.com/ee/user/application_security/sast/index.html#available-cicd-variables).

+### Usage
 
 You should add this component to an existing `.gitlab-ci.yml` file by using the `include:`
 keyword.

+## Infrastructure as Code (IaC) Scanning
+
+### Documentation References
+
+Configuration for IaC scanning can be performed through [CI/CD Variables](https://docs.gitlab.com/ee/ci/variables/index.html) or via the definition of [Inputs](https://docs.gitlab.com/ci/inputs/).

+More information about GitLab Infrastructure as Code scanning is available within [GitLab documentation](https://docs.gitlab.com/user/application_security/iac_scanning/). 
+
+### Usage
+
+You should add this component to an existing `.gitlab-ci.yml` file by using the `include:`
+keyword.
+
+```yaml
+include:
+  - component: gitlab.com/components/sast/iac-sast@<VERSION>

+| ----- | ------------- | ----------- | 
+| `stage` | `test`      | The stage where you want the job to be added | 
+| `image_prefix` | `$CI_TEMPLATE_REGISTRY_HOST/security-products` | Define where all Docker image are pulled from | 
+| `image_tag` | `6` | Tag of the Docker image to use | 
+| `image_suffix` | `""` | Suffix added to image. |
+| `excluded_paths` | `"spec, test, tests, tmp"` | Comma separated list of paths to exclude |
+| `search_max_depth` | `4` | Defines how many directory levels the search for programming languages should span |
