+# Preview Environment
+
+The following document outlines our Github Workflows which faciliate a preview environment deployment pipeline.
+
+## Required Secrets
+
+The following are secrets which are provided by a Skpr platform team member.
+
+* SKPR_PREVIEW_REGISTRY_URL
+* SKPR_PREVIEW_REGISTRY_USERNAME
+* SKPR_PREVIEW_REGISTRY_PASSWORD
+
+## Examples
+
+### Create Preview Environment
+
+Creates a preview environment as part of a pull request workflow.
+
+This workflow will:
+
+* Package the application using the same approach as `skpr package`.
+* Deploy the application onto Preview environment infrastructure.
+* Execute post deploy commands after the preview environment is deployed.
+
+```yaml
+name: Create Preview Environment
+
+on:
+  pull_request:
+    types: [ synchronize, opened, reopened, ready_for_review ]
+
+concurrency:
+  group: preview-${{ github.head_ref }}
+  cancel-in-progress: true
+
+jobs:
+  deploy:
+    uses: skpr/gh-workflows/.github/workflows/preview-create.yml@main
+    secrets:
+      skpr_preview_registry_url: ${{ secrets.SKPR_PREVIEW_REGISTRY_URL }}
+      skpr_preview_username: ${{ secrets.SKPR_PREVIEW_USERNAME }}
+      skpr_preview_password: ${{ secrets.SKPR_PREVIEW_PASSWORD }}
+    with:
+      ref: ${{ github.event.pull_request.head.ref }}
+      eks_cluster_name: NEEDS TO BE CONFIGURED
+      k8s_namespace: NEEDS TO BE CONFIGURED
+      domain: NEEDS TO BE CONFIGURED
+      post_deploy_command: drush deploy
+```
+
+### Delete Preview Environment
+
+Deletes a preview environment when a pull request is closed or moved to a draft state.
+
+```yaml
+name: Delete Preview Environment
+
+on:
+  pull_request:
+    types: [ closed, converted_to_draft ]
+
+concurrency:
+  group: preview-${{ github.head_ref }}
+  cancel-in-progress: true
+
+jobs:
+  deploy:
+    uses: skpr/gh-workflows/.github/workflows/preview-delete.yml@main
+    secrets:
+      skpr_preview_username: ${{ secrets.SKPR_PREVIEW_USERNAME }}
+      skpr_preview_password: ${{ secrets.SKPR_PREVIEW_PASSWORD }}
+    with:
+      ref: ${{ github.event.pull_request.head.ref }}
+      eks_cluster_name: NEEDS TO BE CONFIGURED
+      k8s_namespace: NEEDS TO BE CONFIGURED
+```
