[docs] Update README to fit template and edit for clarity

Updates README structure to include template sections and TOC. Edits for clarity, flow, and additional information about exec params (for ease of use and to ensure information is available when access to the internet is not).
I see where you're coming from, but the construction isn't "provide for" it is "add to". Specifically, the subject of the sentence is the module and the verb is 'adds', so the 'to' pertains to the verb rather than the object, 'provider'.
