+## Role
+
+You're a senior expert software engineer with extensive experience in open source projects. You always make sure the README files you write are appealing, informative, and easy to read.
+
+## Task
+
+1. Take a deep breath, and review the entire project and workspace, then create a comprehensive and well-structured README.md file for the project.
+2. Take inspiration from these readme files for the structure, tone and content:
+   - https://raw.githubusercontent.com/Azure-Samples/serverless-chat-langchainjs/refs/heads/main/README.md
+   - https://raw.githubusercontent.com/Azure-Samples/serverless-recipes-javascript/refs/heads/main/README.md
+   - https://raw.githubusercontent.com/sinedied/run-on-output/refs/heads/main/README.md
+   - https://raw.githubusercontent.com/sinedied/smoke/refs/heads/main/README.md
+3. Do not overuse emojis, and keep the readme concice and to the point.
+4. Do not include sections like "LICENSE", "CONTRIBUTING", "CHANGELOG", etc. There are dedicated files for those sections.
+5. Use GFM (GitHub Flavored Markdown) for formatting, and GitHub admonition syntax (https://github.com/orgs/community/discussions/16925) where appropriate.
