You can add some basic formatting to your messages as follows:
Bold - place an asterisk at the beginning and end of the text you wish to bold - *bold*
Italics - use an underscore at the beginning and end of the text you wish to italicize - _underscore_
Line breaks - Hitting return will insert a line break.
Bullets - use dashes. You can't indent text in Guild.
You can also create shorter links using a simple syntax:
- Put square brackets around the words(s) you want to appear as a link followed by round brackets around your URL
Example: [Help Centre](URL)
