Merge #18170: doc: Minor grammatical changes and flow improvements

7ba9622 doc: Minor grammatical changes and flow improvements (Travin Keith)

Pull request description:

  **Grammar:**

  Line 49: There shouldn't be a period at the end of a phrase.

  Lines 56, 57, 116, 137, and 177: Adding necessary commas

  Lines 103 and 136: Run-on sentence issues fixed.

  Line 176: Fixed punctuation and added necessary conjunction

  Line 178: Singular noun when it should be plural

  **Flow:**

  Line 49: Adding "for" makes it more natural.

  Line 54: Though it's not grammatically incorrect to end a sentence with a preposition in an informal document such as this, the word "followed" is much easier to understand anyway, especially for those who don't have English as their native language.
