• Breaking change? (if so, please describe the impact and migration path for existing application instances)

What changes did you make? (Give an overview)

I found some typos while reading the documentation, so I took the time to pass through it. It's possible that I change some sentences and you preferred the previous version. Just tell me and I'll do the changes.

Thanks

Is there anything you'd like reviewers to focus on?
