+# GitHub Copilot Instructions
+
+This document provides guidelines and best practices for using GitHub Copilot in the `osparc-simcore` repository and other Python and Node.js projects.
+
+## General Guidelines
+
+1. **Test-Driven Development**: Write unit tests for all new functions and features. Use `pytest` for Python and appropriate testing frameworks for Node.js.
+2. **Environment Variables**: Use [Environment Variables Guide](../docs/env-vars.md) for configuration. Avoid hardcoding sensitive information.
+3. **Documentation**: Prefer self-explanatory code; add documentation only if explicitly requested by the developer.
+

+
+## 🛠️Coding Instructions for Python in This Repository
+
+Follow these rules **strictly** when generating Python code:
+
+### 1. Python Version
+
+* Use Python 3.11: Ensure all code uses features and syntax compatible with Python 3.11.
+
+### 2. **Type Annotations**
+
+* Always use full type annotations for all functions and class attributes.
+* ❗ **Exception**: Do **not** add return type annotations in `test_*` functions.
+
+### 3. **Code Style & Formatting**
+
+* Follow [Python Coding Conventions](../docs/coding-conventions.md) **strictly**.
+* Format code with `black`.
+* Lint code with `ruff` and `pylint`.
+
+### 4. **Library Compatibility**
+
+Ensure compatibility with the following library versions:
+
+* `sqlalchemy` ≥ 2.x
+* `pydantic` ≥ 2.x
+* `fastapi` ≥ 0.100
+
+
+### 5. **Code Practices**
+
+* Use `f-string` formatting for all string interpolation except for logging message strings.
+* Use **relative imports** within the same package/module.
+* Place **all imports at the top** of the file.
+* Document functions when the code is not self-explanatory or if asked explicitly.
+
+
+### 6. **JSON Serialization**
+
+* Prefer `json_dumps` / `json_loads` from `common_library.json_serialization` instead of the built-in `json.dumps` / `json.loads`.
+* When using Pydantic models, prefer methods like `model.model_dump_json()` for serialization.
+
+---
+
+## 🛠️Coding Instructions for Node.js in This Repository
+
+* Use ES6+ syntax and features.
+* Follow the `package.json` configuration for dependencies and scripts.
+* Use `eslint` for linting and `prettier` for code formatting.
+* Write modular and reusable code, adhering to the project's structure.
