When you are posting a new note or comment you can use Markdown syntax. Since Pumpa version v0.8.4 inline HTML is also allowed as in standard Markdown.

For example:

  • *stars* make the word emphasised, typically italics
  • **double stars** strong emphasis, typically bold
  • surround links with < and > like so: <http://example.com/>
  • link text [like this](http://example.com/)
  • a hash (#) at the start of the line makes an H1 heading, so be careful with hash tags :-)

Enable the Preview below the text editing window to see what the output will be before posting it to pump.io.

For the full Markdown syntax see John Gruber's page.
