This plugins allows you to create documents with WordPress, and to share them with others so they can also read and edit. Just share the unique link, and anyone with that link will be able to read and edit the document. Alternatively, you can restrict access with a list of email addresses.
At the moment this plugin is very simple. The normal post locking system is used, so no collaborative editing yet!
<h3>Security</h3>
Anyone with the link to the document will be able to edit the document, so be careful to whom you send the link!
<h3>Future</h3>
<ul>
<li>Allow posts and pages to be shared in the same way.</li>
<li>There will be option to fine tune permissions. You’ll be able to choose if
<ul>
<li>anyone with the link can read,</li>
<li>anyone with the link can edit,</li>
<li>certain email addresses can read, or</li>
<li>certain email addresses can edit.</li>
</ul>
</li>
<li>As part of the Gutenberg project, we’ll look into collaborative editing.
<ul>
<li>At first improve post locking, so others can still view the document, but 
not edit. (Read only.)</li>
<li>Read only, but live updated.</li>
<li>Lock on a block level, let anyone edit the rest.</li>
<li>Maybe full collaborative editing.</li>
</ul>

DocuPress

Simple to use with a nice looking interface that blends in with the standard WordPress dashboard.

It would be nice if, in future, some extra features, specific for documentation, could be added. For example, an automatically generated index based upon content headings.
