+# GitHub Action to update image tag in target Helm values.yaml
+
+This [GitHub Action](https://github.com/actions) checks out target repo, updates image tag in specified target file and pushes the changes.
+
+You can add this action to your GitHub workflow for Ubuntu runners (e.g. `runs-on: ubuntu-latest`) as follows:
+
+```yaml
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    env:
+      DEPLOY_GITOPS_REPO: 'lwitkowski/playground-gitops'
+      DEPLOY_TOKEN: ${{ secrets.DEPLOY_TOKEN }}
+
+    steps:
+      - name: Deploy to test
+        uses: lwitkowski/gitops-deploy-tag-action@master
+        with:
+          target-file: 'sample-service/test/values.yaml'
+
+      - name: Deploy to production
+        uses: lwitkowski/gitops-deploy-tag-action@master
+        with:
+          target-file: 'sample-service/prod/values.yaml'
+```
+
+## Configuration
+
+The action can be configured by the following options.
+
+|Option|Default Value|Description|
+|:-----|:-----:|:----------|
+|`gitops-repo`|`${DEPLOY_GITOPS_REPO}`|Owner and name of target gitops repository name where yaml file is stored. |
+|`target-file`|mandatory|Path to yaml file inside gitops repo to be updated.|
+|`docker-image-tag`|`${GITHUB_SHA::6}`|Docker image tag to be set in target yaml file.|
+|`env.DEPLOY_TOKEN`|mandatory|Github access token with write permission to gitops repo. Should be set as env variable in calling workflow.|
+
+
+Note: Running this action on `pull_request_target` events is [dangerous if combined with code checkout and code execution](https://securitylab.github.com/research/github-actions-preventing-pwn-requests).
