More in depth correction of the README.md

[PoorPocketsMcNewHold]

An answer to the nitpicky, but actually true, its correction pull request you’ve done.

Here's the additional corrections I would like to propose :

• Usage of correct quotations marks.

    ”Good morning, Dave,” said HAL.
    ’Good morning, Dave,’ said HAL.

These same systems often drew the grave accent (`, U+0060) as an open quote glyph (actually a high-reversed-9 glyph, to preserve some usability as a grave). Thus, using a grave accent instead of a quotation mark as the opening quote gave a proper appearance of single quotes at the cost of semantic correctness. Nothing similar was available for the double quote, so many people resorted to using two single quotes for double quotes, which would look like the following:

    ‛‛Good morning, Dave,’’ said HAL.
    ‛Good morning, Dave,’ said HAL.

In languages that use the curved “…” quotation marks, they are available[b] in:

    none
[b] : in 1st or 2nd level access, i.e., specific key or using the ⇧ Shift key; not 3rd or 4th level access, i.e., using Alt Gr key or ⌥ Opt key, in conjunction or not with the ⇧ Shift key.

• Useless intensifier replaced by crucial. As an alternative to the over-used intensifier 'extremely', I’ve preferred using crucial, as not only it is extremely used (See that example), but it is currently used with the word 'important' which is defined by the Oxford Dictionary as :

‘important habitats for wildlife’
‘it is important to avoid monosyllabic answers’
[sentence adverb] ‘the speech had passion and, more important, compassion’

Which is in itself, already a strong usage of the word.

• Usage of the capitalized acronym form of CDN. As it is the acronym of Content Delivery Network, or Content Distribution Network. The need of writing it in its capitalized form result of :
  In formal writing for a broad audience, the expansion is typically given at the first occurrence of the acronym within a given text, for the benefit of those readers who do not know what it stands for. The capitalization of the original term is independent of it being acronymized, being lowercase for a common noun such as frequently asked questions (FAQ) but uppercase for a proper noun such as the United Nations (UN) (as explained at Case > Casing of expansions).

• Missing capitalization of 'get your fingerprint' after a point.

• Usage of the capitalized acronym form of URL. As, it is the acronym of Uniform Resource Locator. The need of writing it in its capitalized form result of :
  In formal writing for a broad audience, the expansion is typically given at the first occurrence of the acronym within a given text, for the benefit of those readers who do not know what it stands for.

• Correct orthography of well-known. It is either accepted as 'well known' or 'well-known'.

• Usage of the capitalized acronym form of API. As, it is the acronym of Application Programming Interface. The need of writing it in its capitalized form result of :
  In formal writing for a broad audience, the expansion is typically given at the first occurrence of the acronym within a given text, for the benefit of those readers who do not know what it stands for.

• Missing capitalization of 'Firefox' as it is a proper noun.
