The hardcoded user-specific path makes this script non-portable. Consider using a relative path or detecting the project root dynamically (e.g., using $PSScriptRoot or looking for a marker file like pyproject.toml in parent directories).

| $projectRoot = "c:\Users\PRAJWAL\OneDrive\Desktop\quantresearch\QuantResearch" | |
| # Determine project root dynamically, prefer directory containing pyproject.toml | |

| $markerFile = "pyproject.toml" | |
| $currentDir = $PSScriptRoot | |
| while ($currentDir -and -not (Test-Path -LiteralPath (Join-Path $currentDir $markerFile))) { | |

The documentation contains hardcoded user-specific paths that won't work for other developers. Replace with relative paths or generic placeholders like '<PROJECT_ROOT>' throughout the documentation.

A real API key appears to be exposed in the documentation. This should be replaced with a placeholder like 'your-finnhub-api-key-here' to prevent potential security issues.

The example JWT_SECRET contains a potentially real development secret. Replace with a generic placeholder like 'your-secret-key-here' to prevent developers from copying insecure secrets into production.

Replace hardcoded user-specific paths with generic placeholders or relative paths to make the documentation portable across different development environments.
