This is one of those blog posts which is mainly for my benefit 😀.

To paste Markdown text into Atlassian Confluence wiki:

  1. Use Ctrl-Shift-V (to paste without formatting)
  2. Click on the Paste Options menu in Confluence and select Use Markdown (the default is)

Confluence's Paste Options menu

If you prepared your Markdown in Visual Studio Code (as I often do), then the 'paste without format' is important as by default VS Code copies text with a 'plain text/code' formatting flavour, and this means you don't get offered the paste options menu.
