What

Changes to the docs

Why

1. The link to the CONTRIBUTING.md template didn't actually link to the template.
2. The install line didn't paste well in terminals
3. We now link to CONTRIBUTING.md from Storybook, so devs looking for these docs can more easily find them.

How

By updating the docs
