 **mwn** is a modern MediaWiki bot framework in NodeJS, orginally adapted from [mwbot](https://github.com/Fannon/mwbot).
 
-Development status: **Unstable**. Versioning: while mwn is in version 0, changes may be made to the public interface with a change in the minor version number.

 Documentation given below is incomplete. There are a number of additional classes such as `bot.title`, `bot.wikitext`, `bot.page`, etc that provide useful functionality but aren't documented.

-#### Set up a bot password
+#### MediaWiki version
+mwn is written for and tested on the latest version of MediaWiki used on WMF wikis.
 
-To be able to login to the wiki, you have to set up a bot password using the wiki's [Special:BotPasswords](https://en.wikipedia.org/wiki/Special:BotPasswords) page.
+#### Set up a bot password or OAuth credentials
+
+mwn supports authentication via both BotPasswords and via OAuth. Use of OAuth is recommended as it does away the need for separate API requests for logging in, and is also a bit more secure. 
+
+Bot passwords may be a bit easier to set up. To generate one, go to the wiki's [Special:BotPasswords](https://en.wikipedia.org/wiki/Special:BotPasswords) page. 
 
 If you're migrating from mwbot, note that:
 - `edit` in mwbot is different from `edit` in mwn. You want to use `save` instead.
