Step-by-step instructions

  1. Open the intended practice workspace in Visual Studio Code and confirm its folder name and Workspace Trust state.
  2. Run a small practice script.
  3. Save the relevant files and review the Problems panel, terminal, Source Control view or browser preview as appropriate.
  4. Check filenames, relative paths, console messages, keyboard use, mobile layout and privacy before continuing.
  5. Confirm that you can read basic program flow, then create a clear commit, backup or saved checkpoint.
Ian's practical tip: Work in one named project folder, preview after small changes, read the actual error message and keep a recoverable version before broad edits.
