Can you tell me how to format an url in rst?<|im_end|>
<|im_start|>assistant
In reStructuredText, URLs are formatted using the standard inline format, which is as follows:

```
`URL name <URL link>`_
```

For example, if you want to link to the Google homepage, the formatting would look like this:

```
`Google <https://www.google.com>`_
```

The _ at the end of the line is important, as it allows the URL to be recognized as an active link by reStructuredText parsers.<|im_end|>

I've not understood it. Can you explain it to me more thoroughly?<|im_end|>
<|im_start|>assistant
Sure. Let's look at the example given:

`Click here to open site <http://www.example.org/>`_

The link starts with ` and ends with `_  to signify the start and the end of the special syntax. You can place the text the reader can click on to reach the external page right after the starting `. You can do this up until the point where you type <, signifying the start of the actual URL. The URL is terminated by >, and the `_ ends the special syntax.

You can use this to offer your reader a more pleasing look for links than plain URLs.<|im_end|>
