I choose to use uncontracted 8 dot braille output because I am generally needing to see the range of characters used in coding that are seldom used in literary work, including {} and \ for example.

We'll worry about that stuff later. Use of the right editor can make conversion faster; we all have our favourites. In general though, people will write a command line that is of the form: "pandoc -s file.md -o file.html" which says take my source file called "file.md" and make the output file "file.html". Even if the editor has a conversion tool linked to it, this command line is what gets done behind the scenes.

> Back to me: I've used plain text characters to do some formatting, and LaTeX users will see the familiar construct for an inline mathematical element as well as an equation that will be on its own line in the document. The use of the number signs (pound or hash to some people) suggests some sort of heading based on the way it appears; in fact this will be put as a <h2> element in HTML which means heading level 2. It looks like I've tried to emphasize the "population mean" using some stars/asterisks; two of them means bold, only one would have been italic, and in a fit of logic, 3 means bold italic!

For example, if I type `mean()` in a document, I am telling my students that the command "mean" is used. I put the () there to make a point, but the use of the backticks (also known as accent grave) turns that element into typewriter font.
