# How do I add someone who is not on Authorea to my document?

### Adding a coauthor

If a coauthor you want to work with is not on Authorea, when you click **Share** or **Manage Collaborators**, you have a chance to enter their email address. They will receive a notification to complete sign up and immediately collaborate with you on the document. 

You can also add a coauthor to the author list without inviting them to Authorea (they will not receive an email); to do so, simply type their name in the input box and add them as "a name".

### Sharing your document via a link 
To show someone your work and receive comments (even if the article is not public or published), access your document in Edit mode and you can click **Share** and then create a shareable URL, i.e. a secret link which you can share with your colleague.
