You can change Showdown's default behavior via options.

Set option

Globally

Setting an option globally affects all Showdown instances.

showdown.setOption('optionKey', 'value');

Locally

Setting an option locally affects the specified Converter object only. You can set local options via:

=== "Constructor"

```js
var converter = new showdown.Converter({optionKey: 'value'});
```

=== "setOption() method"

```js
var converter = new showdown.Converter();
converter.setOption('optionKey', 'value');
```

Get option

Showdown provides both local and global methods to retrieve previously set options:

=== "getOption()"

```js
// Global
var myOption = showdown.getOption('optionKey');

//Local
var myOption = converter.getOption('optionKey');
```

=== "getOptions()"

```js
// Global
var showdownGlobalOptions = showdown.getOptions();

//Local
var thisConverterSpecificOptions = converter.getOptions();
```

Get default options

You can get Showdown's default options with:

var defaultOptions = showdown.getDefaultOptions();
