- Add H1 header
- `Read this` ... right alignmements
- Split a bit first paragraph to highlight welcome.
- Introduce Pull Request acronym.
- trademarks / typos: GitHub, YouTube, Pull Request
- Update GitHub links urls. `help`/`guides` subdomain was moved to `docs` so now a 301 Redirect is skipped.
- Details block added, with center align. When clicked, the contributor graphs is toggled.
- Some bolds to highlight common resources formating issues (like in CONTRIBUTING)
- Repo name in monospace font
- Re-worded last part of 4th paragraph to explain that no new PR is needed to open if there are linter errors or changes are requested. Now it's more clear, I thought.
