 # Spec Contributions
 
 The specification is first authored as a Microsoft Word (docx) file and then generated into Markdown and PDF formats.
-Due to the binary format of docx files, and the merging difficulties that may come with it, it is preferred that any suggestions or problems found in the spec should be [filed as issues](https://github.com/Microsoft/TypeScript/issues/new) rather than sent as pull requests.
