Web Tutorials: Issues and Improvements

### General Issue with set up instructions

**Issue:** Library file creation instructions (in all tutorials) should specify cd src directory first, or import paths in page.tsx files need adjustment

The issue points to a discrepancy in setup instructions across tutorials. First, locate the tutorial files in the repository, likely under a `src` directory. Check the `page.tsx` files for import paths and compare them with the instructions. The fix involves updating the documentation to either instruct users to `cd src` first or adjust the import paths. Verify the change by following the updated instructions in a fresh environment.
