Markdown is plain text with symbols for formatting. If the place you paste into does not read Markdown, it shows the symbols as they are: **Important** stays two pairs of asterisks, and ## Weekly update keeps its hash marks. The fix is to paste the kind of copy that destination understands.

document.html, which opens in any browser.Paste this into the Editor box. It has the four things that most often break: a heading, bold text, a list and a link.
## Weekly update **Important:** the office is closed Friday. - Payroll runs Thursday - Send receipts by noon [Team calendar](https://example.com/calendar)
Copy it into the destination the way described above. If those four survive, the long document will too.
Even in a Markdown editor, two common things look lost after a paste:

Line one and Line two on consecutive lines render as Line one Line two. Leave a blank line to start a new paragraph, or end the first line with a backslash \ (or two spaces) for a line break inside the paragraph.2. directly under a sentence is read as part of that sentence. Leave a blank line above the list. Starting at 1. is the safest.Some sites, such as GitHub comments, treat a single Enter as a line break anyway. The preview here follows the standard rule, which is what README files and most Markdown documents use.
<p> and <strong> tags: you pasted Copy HTML into a normal editor. Copy from the Preview panel instead.The preview is rendered in your browser and your text is not uploaded. Open the free Markdown Editor.
