# prosemirror-markdown [ [**WEBSITE**](http://prosemirror.net) | [**ISSUES**](https://github.com/prosemirror/prosemirror-markdown/issues) | [**FORUM**](https://discuss.prosemirror.net) | [**GITTER**](https://gitter.im/ProseMirror/prosemirror) ] This is a (non-core) module for [ProseMirror](http://prosemirror.net). ProseMirror is a well-behaved rich semantic content editor based on contentEditable, with support for collaborative editing and custom document schemas. This module implements a ProseMirror [schema](https://prosemirror.net/docs/guide/#schema) that corresponds to the document schema used by [CommonMark](http://commonmark.org/), and a parser and serializer to convert between ProseMirror documents in that schema and CommonMark/Markdown text. This code is released under an [MIT license](https://github.com/prosemirror/prosemirror/tree/master/LICENSE). There's a [forum](http://discuss.prosemirror.net) for general discussion and support requests, and the [Github bug tracker](https://github.com/prosemirror/prosemirror/issues) is the place to report issues. We aim to be an inclusive, welcoming community. To make that explicit, we have a [code of conduct](http://contributor-covenant.org/version/1/1/0/) that applies to communication around the project. ## Documentation @schema @MarkdownParser @ParseSpec @defaultMarkdownParser @MarkdownSerializer @MarkdownSerializerState @defaultMarkdownSerializer
