Check headers are correct

TLDR; Headers should use the#,## etc to format different levels of headers, and not be underlines using===== or ``-----`, or be psuedo header using bold

Check all headers on the documentation - headers should use the hash style of declaration rather then be underlined with equals or dashes. The more hashes, the more of a subheading. Eg:

• # is equal to<h1>
• ## is equal to<h2>
• ### is equal to<h3>
• #### is equal to<h4>
• ##### is equal to<h5>

Headings should be appropriate for their level in the documentation.

Psuedo headers using bold tags** should be replaced with appropriate level of heading tag.
