--- title: Autoformatting category: features --- The {@link module:autoformat/autoformat~Auformat} feature allows you to quickly apply formatting to the content you're writing. This feature is enabled by default in all builds. It is also included in the {@link module:presets/article~Article Article preset}. ## Block formatting * Start a line with `*` or `-` followed by a space to create a bulleted list. * Start a line with `1.` or `1)` followed by a space to create a numbered list. * Start a line with `#` or `##` or `###` followed by a space to create a heading 1, heading 2 or heading 3 (up to heading 6 if {@link module:heading/heading~HeadingConfig#options} defines more headings). * Start a line with `>` followed by a space to create a block quote. ## Inline formatting * Type `**text**` or `__text__` to make "text" bold. * Type `*text*` or `_text_` to make "text" italic. ## Test here Example: 1. Delete all content. 2. Press # and then Space. 3. The current line will be turned into a heading. {@snippet examples/classic-editor} ## Installation To add this feature to your editor install the [`@ckeditor/ckeditor5-autoformat`](https://www.npmjs.com/package/@ckeditor/ckeditor5-autoformat) package: ``` npm install --save @ckeditor/ckeditor5-autoformat ``` And add it to your plugin list: ```js import Autoformat from '@ckeditor/ckeditor5-autoformat/src/autoformat'; ClassicEditor .create( { plugins: [ Autoformat, ... ] } ) .then( ... ) .catch( ... ); ``` If you are using editor build see how to {@linkTODO customize builds}. ## Create your own autoformatters The {@link module:autoformat/autoformat~Auformat} feature bases on {@link module:autoformat/blockautoformatengine~BlockAuformatEngine} and {@link module:autoformat/inlineautoformatengine~InlineAuformatEngine} tools to create the autoformatters mentioned above.
