String indexing weirdly worded

[Leafmun-certii]

• I have searched open and closed issues and pull requests for duplicates, using these search terms:
  • 8.2
  • 8-2
  • string slice
• I have checked the latest main branch to see if this has already been fixed, in this file:
  • No

URL to the section(s) of the book with this problem:
https://github.com/rust-lang/book/blob/main/src/ch08-02-strings.md#slicing-strings

Description of the problem:
In the following sentence

If you really need to use indices to create string slices, therefore, Rust asks you to be more specific.
The "therefore" breaks up the flow of the sentence in a way that is confusing.

Suggested fix:
Either therefore at the start of the sentence:

Therefore, if you really need to use indices to create string slices, Rust asks you to be more specific.
Or remove it all together to make the conclusion more impactful:
If you really need to use indices to create string slices, Rust will ask you to be more specific.
