Markdown注释和反斜线转义 语法
comment and backslash escapes
Hiding content with comments
We can hide content from the rendered Markdown by placing the content in an HTML comment.
<!-- This content will not appear in the rendered Markdown -->
Ignoring Markdown formatting
We can ignore (or escape) Markdown formatting by using \
before the Markdown character.
Let's rename \*our-new-project\* to \*our-old-project\*.
