Can you tell me how to format an url in rst?
user
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.
