📝 Walkthrough

Walkthrough

The quick-start documentation for isaacteleop now includes guidance to use an isolated Python environment before installation. A new expandable section titled "New to Python environments?" provides a minimal workflow using uv for environment setup. The "More Information" reference section is extended with links to documentation for uv, conda, and Python's venv module to support the newly introduced inline references.
