坚果之云 Markdown假设您添加一个URL作为到段落的标准URL链接，并且在Markdown中看起来像这样：
In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends
of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to
eat: it was a [hobbit-hole](https://en.wikipedia.org/wiki/Hobbit#Lifestyle “Hobbit lifestyles”), and that means comfort.
尽管它可能指向有趣的附加信息，但显示的URL确实不会给现有的原始文本增加太多，除了使其难以阅读之外。要解决此问题，您可以改为设置网址格式：
In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends
of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to
eat: it was a [hobbit-hole][1], and that means comfort.
[1]: <https://en.wikipedia.org/wiki/Hobbit#Lifestyle> “Hobbit lifestyles”
在上述两种情况下，呈现的输出将相同：
在地上的一个洞里住着一个霍比特人。这不是一个肮脏，肮脏，潮湿的洞，里面充满蠕虫的末端和难闻的气味，也没有一个干燥，裸露，沙质的洞，里面没有东西可以坐下或进食：那是一个霍比特洞，意味着舒适。
链接HTML为：
