## Checklist

- [ ] The resource fits the section it is placed in
- [ ] The link opens and the content matches the title
- [ ] Free resources are preferred; a paid one is included only if clearly better than the free options
- [ ] No pile of entries from a single author or creator without a clear reason
- [ ] Advanced material is labeled as such, so beginners are not overwhelmed
