+# Get Images From Files Action
+
+A reusable Gitea Action, that extracts docker images from selected files in a repository.
+
+The action supports Dockerfiles and Kubernetes manifests. Other files are supported if they have a recognizable image reference.
+
+## Usage
+
+### Basic Usage
+
+```yaml
+- name: Get Images From Files
+  uses: https://gitea.t000-n.de/t.behrendt/trivy-actions/get-images-from-files@0.0.1
+  with:
+    files: |
+        - Dockerfile
+        - k8s/50_deployment.yaml
+        - values/traefik.yaml
+```
+
+### Complete Example
+
+```yaml
+name: Get Images From Files
+on: [push, pull_request]
+
+jobs:
+  get-images-from-files:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: Get Images From Files
+        uses: https://gitea.t000-n.de/t.behrendt/trivy-actions/get-images-from-files@0.0.1

+            files: |
+              - Dockerfile
+              - k8s/50_deployment.yaml
+              - values/traefik.yaml
+```
