-# structurizr-pr-comment
-This GitHub Action automatically makes a comment on each pull requests which updates Structurizr diagrams. It's designed to simplify the process of visualizing architecture diagrams changes in your codebase.
+# Comment on PR with Structurizr Diagrams Action
+
+## Introduction
+
+This GitHub Action, designed to complement the [Generate Structurizr Diagrams Images from DSL](https://github.com/marketplace/actions/generate-structurizr-diagrams-images-from-dsl) action, automatically comments on pull requests with the previously generated Structurizr diagrams. It ensures that team members can easily review the latest architecture diagrams directly within the context of a PR.
+
+## Prerequisites
+
+To use this action effectively, you should have:
+
+- A GitHub repository.
+- Completed the setup of the "Generate Structurizr Diagrams Images from DSL" action in your repository.
+  
+## Usage
+
+This action is meant to be used in a separate workflow that triggers after the "Generate Structurizr Diagrams Images from DSL" workflow. To set it up:
+
+1. **Create a workflow file**: In your repository's `.github/workflows` directory, create a new file (e.g., `structurizr-diagrams-comment.yml`) with the following content:
+
+```yaml
+name: Comment on PR with Structurizr Diagrams
+
+on:
+    workflow_run:
+        types:
+            - completed
+        workflows:
+            - "Update Structurizr Diagrams"
+
+jobs:
+    comment-on-pr:
+        if: github.event.workflow_run.conclusion == 'success'
+        runs-on: ubuntu-latest
+        steps:
+        - uses: sebastienfi/structurizr-pr-comment@v1
+```
+
+## How It Works
+
+- The action triggers after the "Update Structurizr Diagrams" workflow completes.
+- It retrieves information about the PR and lists the generated diagram files.
+- If diagrams are updated, the action posts or updates a comment in the PR with the diagrams.
+
+## Contributing
+
+Contributions to improve this action are welcome. Ensure your contributions are well-documented and follow the coding standards of this project.
