fix: Improve style and readability of the distribution doc

[m-czernek]

In this PR, I'm providing 2 fixes:

1. When a sentence includes a secondary/inner sentence, it should finish with a single punctuation sign, e.g. and then he asked: 'how are you?' instead and then he asked: 'how are you?'.

2. Simplifying the note, which is a bit awkwardly phrased.

Would you welcome further PRs to fix some nits in your documentation?
