+### Scan CI Pipeline (w/ Trivy Config)
+
+```yaml
+name: build
+on:
+  push:
+    branches:
+    - main
+  pull_request:
+jobs:
+  build:
+    name: Build
+    runs-on: ubuntu-20.04
+    steps:
+    - name: Checkout code
+      uses: actions/checkout@v4
+
+    - name: Run Trivy vulnerability scanner in fs mode
+      uses: aquasecurity/trivy-action@0.20.0
+      with:
+        scan-type: 'fs'
+        scan-ref: '.'
+        trivy-config: trivy.yaml
+```
+
+In this case `trivy.yaml` is a YAML configuration that is checked in as part of the repo. Detailed information is available on the Trivy website but an example is as follows:
+```yaml
+format: json
+exit-code: 1
+severity: CRITICAL
+secret:
+  config: config/trivy/secret.yaml
+```
+
+It is possible to define all options in the `trivy.yaml` file. Specifying individual options via the action are left for backward compatibility purposes. Defining the following is required as they cannot be defined with the config file:
+- `scan-ref`: If using `fs, repo` scans.
+- `image-ref`: If using `image` scan.
+- `scan-type`: To define the scan type, e.g. `image`, `fs`, `repo`, etc.
+
+#### Order of preference for options
+Trivy uses [Viper](https://github.com/spf13/viper) which has a defined precedence order for options. The order is as follows:
+- GitHub Action flag
+- Environment variable
+- Config file
+- Default
+
+### Cache
+The action has a built-in functionality for caching and restoring [the vulnerability DB](https://github.com/aquasecurity/trivy-db), [the Java DB](https://github.com/aquasecurity/trivy-java-db) and [the checks bundle](https://github.com/aquasecurity/trivy-checks) if they are downloaded during the scan.
+The cache is stored in the `$GITHUB_WORKSPACE/.cache/trivy` directory by default.
+The cache is restored before the scan starts and saved after the scan finishes.
+
+It uses [actions/cache](https://github.com/actions/cache) under the hood but requires less configuration settings.
+The cache input is optional, and caching is turned on by default.
+
+#### Disabling caching
+If you want to disable caching, set the `cache` input to `false`, but we recommend keeping it enabled to avoid rate limiting issues.
+
+```yaml
+    - name: Run Trivy scanner without cache
+      uses: aquasecurity/trivy-action@0.20.0
+      with:
+        scan-type: 'fs'
+        scan-ref: '.'
+        cache: 'false'
+```
+
+#### Updating caches in the default branch
+Please note that there are [restrictions on cache access](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/caching-dependencies-to-speed-up-workflows#restrictions-for-accessing-a-cache) between branches in GitHub Actions.
+By default, a workflow can access and restore a cache created in either the current branch or the default branch (usually `main` or `master`).
+If you need to share caches across branches, you may need to create a cache in the default branch and restore it in the current branch.
+
+To optimize your workflow, you can set up a cron job to regularly update the cache in the default branch.
+This allows subsequent scans to use the cached DB without downloading it again.
+
+```yaml
+# Note: This workflow only updates the cache. You should create a separate workflow for your actual Trivy scans.
+# In your scan workflow, set TRIVY_SKIP_DB_UPDATE=true and TRIVY_SKIP_JAVA_DB_UPDATE=true.

+          path: ${{ github.workspace }}/.cache/trivy
+          key: cache-trivy-${{ steps.date.outputs.date }}
+```
+
+When running a scan, set the environment variables `TRIVY_SKIP_DB_UPDATE` and `TRIVY_SKIP_JAVA_DB_UPDATE` to skip the download process.
+
+```yaml
+    - name: Run Trivy scanner without downloading DBs
+      uses: aquasecurity/trivy-action@0.20.0
+      with:
+        scan-type: 'image'

 It's also possible to scan your git repos with Trivy's built-in repo scan. This can be handy if you want to run Trivy as a build time check on each PR that gets opened in your repo. This helps you identify potential vulnerablites that might get introduced with each PR.

+### Using Trivy to scan Infrastructure as Code
+It's also possible to scan your IaC repos with Trivy's built-in repo scan. This can be handy if you want to run Trivy as a build time check on each PR that gets opened in your repo. This helps you identify potential vulnerablites that might get introduced with each PR.
+
+If you have [GitHub code scanning](https://docs.github.com/en/github/finding-security-vulnerabilities-and-errors-in-your-code/about-code-scanning) available you can use Trivy as a scanning tool as follows:
+```yaml
+name: build
+on:
+  push:
+    branches:
+      - main
+  pull_request:
+jobs:
+  build:
+    name: Build
+    runs-on: ubuntu-20.04
+    steps:
+      - name: Checkout code
+        uses: actions/checkout@v4
+
+      - name: Run Trivy vulnerability scanner in IaC mode
+        uses: aquasecurity/trivy-action@0.20.0
+        with:
+          scan-type: 'config'
+          hide-progress: true
+          format: 'sarif'
+          output: 'trivy-results.sarif'
+          exit-code: '1'
+          ignore-unfixed: true
+          severity: 'CRITICAL,HIGH'
+
+      - name: Upload Trivy scan results to GitHub Security tab
+        uses: github/codeql-action/upload-sarif@v3
+        with:
+          sarif_file: 'trivy-results.sarif'
+```
+
+### Using Trivy to generate SBOM
+It's possible for Trivy to generate an [SBOM](https://www.aquasec.com/cloud-native-academy/supply-chain-security/sbom/) of your dependencies and submit them to a consumer like [GitHub Dependency Graph](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/about-the-dependency-graph).
+
+The [sending of an SBOM to GitHub](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/using-the-dependency-submission-api) feature is only available if you currently have GitHub Dependency Graph [enabled in your repo](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/configuring-the-dependency-graph#enabling-and-disabling-the-dependency-graph-for-a-private-repository).
+
+In order to send results to GitHub Dependency Graph, you will need to create a [GitHub PAT](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) or use the [GitHub installation access token](https://docs.github.com/en/actions/security-guides/automatic-token-authentication) (also known as `GITHUB_TOKEN`):
+
+```yaml
+---
+name: Pull Request
+on:
+  push:
+    branches:
+    - main
+
+## GITHUB_TOKEN authentication, add only if you're not going to use a PAT
+permissions:
+  contents: write
+
+jobs:
+  build:
+    name: Checks
+    runs-on: ubuntu-20.04
+    steps:
+      - name: Checkout code
+        uses: actions/checkout@v4
+
+      - name: Run Trivy in GitHub SBOM mode and submit results to Dependency Graph
+        uses: aquasecurity/trivy-action@0.20.0
+        with:
+          scan-type: 'fs'
+          format: 'github'
+          output: 'dependency-results.sbom.json'
+          image-ref: '.'
+          github-pat: ${{ secrets.GITHUB_TOKEN }} # or ${{ secrets.github_pat_name }} if you're using a PAT
+```
+
+When scanning images you may want to parse the actual output JSON as Github Dependency doesn't show all details like the file path of each dependency for instance.
+
+You can upload the report as an artifact and download it, for instance using the [upload-artifact action](https://github.com/actions/upload-artifact):
+
+```yaml
+---
+name: Pull Request
+on:
+  push:
+    branches:
+    - main
+
+## GITHUB_TOKEN authentication, add only if you're not going to use a PAT
+permissions:
+  contents: write
+
+jobs:
+  build:
+    name: Checks
+    runs-on: ubuntu-20.04
+    steps:
+      - name: Scan image in a private registry
+        uses: aquasecurity/trivy-action@0.20.0
+        with:
+          image-ref: "private_image_registry/image_name:image_tag"
+          scan-type: image
+          format: 'github'
+          output: 'dependency-results.sbom.json'
+          github-pat: ${{ secrets.GITHUB_TOKEN }} # or ${{ secrets.github_pat_name }} if you're using a PAT
+          severity: "MEDIUM,HIGH,CRITICAL"
+          scanners: "vuln"
+        env:
+          TRIVY_USERNAME: "image_registry_admin_username"
+          TRIVY_PASSWORD: "image_registry_admin_password"
+
+      - name: Upload trivy report as a Github artifact
+        uses: actions/upload-artifact@v4
+        with:
+          name: trivy-sbom-report
+          path: '${{ github.workspace }}/dependency-results.sbom.json'
+          retention-days: 20 # 90 is the default
+```
+
 ### Using Trivy to scan your private registry
 It's also possible to scan your private registry with Trivy's built-in image scan. All you have to do is set ENV vars.
