# Basic Usage

The `CommonMarkConverter` class provides a simple wrapper for converting Markdown to HTML:

```php
require __DIR__ . '/vendor/autoload.php';

use League\CommonMark\CommonMarkConverter;

$converter = new CommonMarkConverter();
echo $converter->convertToHtml('# Hello World!');

// <h1>Hello World!</h1>
```

Or if you want GitHub-Flavored Markdown:

```php
require __DIR__ . '/vendor/autoload.php';

use League\CommonMark\GithubFlavoredMarkdownConverter;

$converter = new GithubFlavoredMarkdownConverter();
echo $converter->convertToHtml('# Hello World!');

// <h1>Hello World!</h1>
```

**Important:** See the [security](/1.5/security/) section for important details on avoiding security misconfigurations.

[Additional customization](/1.5/customization/overview/) is also possible, and we have many handy [extensions](/1.5/extensions/overview/) to enable additional syntax and features.

## Supported Character Encodings

Please note that only UTF-8 and ASCII encodings are supported.  If your Markdown uses a different encoding please convert it to UTF-8 before running it through this library.
