Teach me Markdown basics for my notes

Teaches the eight Markdown marks you need for everyday notes, each with a one-line example and a short practice note to try.

Task: Teach me the Markdown marks I need to write everyday notes, starting from zero. Context: I write [kind of notes, such as meeting notes or study notes] in [editor or app name]. I have never used Markdown and I want to be comfortable within [time, such as 15 minutes]. Rules: - Cover exactly eight marks, chosen for my kind of notes, and say why each earns its place. - Show each mark as a one-line example of what I type and what I should see. - Editors differ in what they support. Tell me which marks to test first in my editor and how to tell if one is not supported. Result: A list of eight entries with the mark, the example and the reason. Then one practice note of at most 6 lines that uses all eight marks, for me to retype.
