Open any .plot.json file to see the custom Plot JSON editor\n2. Use Ctrl+Shift+P to access the 'Hello World' command\n3. Check the 'Hello World' view in the Explorer panel\n\n## Python Scripts\n\nPython scripts can be run directly with F5 or using the Run button in VS Code. The environment is pre-configured to use the virtual environment automatically.\n\nAlternatively, you can run scripts manually:\n\n\`\`\`bash\ncd tests\n./venv/bin/python move_point_north_simple.py\n\`\`\`\n\nThis environment includes sample data files for testing the extension features." > /home/coder/workspace/README.md
