Erinnemori piggybacks off of Factor's custom markup language, which works as follows:

Characters * _ ^ ~ and % should be escaped as 

 \* \_ \^ \~ and \%

Italics 

_Italics_

Bold Text 

*Bold Text*

Super scripts and Sub scripts 

^Super^scripts and ~Sub~scripts

Inline Code 

%Inline-Code%

Careful, inline code spans don't automatically escape special characters. 

 Code Blocks

EDIT: There doesn't seem to be a way to properly escape the syntax for these: https://pomf2.lain.la/f/ys199is.gif

A Header 

= A Header =

Any other text, including a space, on the same line as a header will break it.

Custom Links 

 [[https://example.com|Custom Links]]

Images can be inlined as well.

Alt Text

  • Unordered
  • Lists 
- Unordered

  1. Ordered
  2. Lists 
# Ordered
# Lists

No nesting is supported in lists. It's all a bit janky, I might see about fixing some of this stuff later.
