The extractor should handle:

- YAML front matter extraction
- Heading structure
- **Bold text** and *italic text*
- Lists and other formatting

### Code Examples

Here is some inline `code` and a code block:

```java
public class Example {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
```

With a server that holds a certificate and a client that trusts it we have enough for an HTTPS
handshake. The best part of this example is that we don't need to make our test code insecure with a
a fake `HostnameVerifier` or `X509TrustManager`.

Certificate Authorities
-----------------------

The above example uses a self-signed certificate. This is convenient for testing but not

fix. Even if you think it's relatively minor, it's helpful to know what people
are working on. And as mentioned above, API changes should be discussed
thoroughly before moving to code.

Some examples of types of pull requests that are immediately helpful:

  - Fixing a bug without changing a public API.
  - Fixing or improving documentation.
  - Improvements to Maven configuration.

    /**
     * Parses a comma-separated string of pruned tag configurations into an array of PrunedTag objects.
     * Each tag configuration follows the pattern: tagname[attr=value].classname#id
     *
     * Examples:
     * - "div.content" matches div elements with class "content"
     * - "span#header" matches span elements with ID "header"
     * - "p[data-type=ad]" matches p elements with data-type attribute equal to "ad"
     *

      .url(url)
      .post(body)
      .build();
  try (Response response = client.newCall(request).execute()) {
    return response.body().string();
  }
}
```
