 This plugin allows users to use their [OpenID](http://openid.net/) to log
 into the wiki.
 
-The plugin needs the [[cpan Net::OpenID::Consumer]] perl module. The
-[[cpan LWPx::ParanoidAgent]] perl module is used if available, for added
-security. Finally, the [[cpan Crypt::SSLeay]] perl module is needed to support
-users entering "https" OpenID urls.
+The plugin needs the [[!cpan Net::OpenID::Consumer]] perl module.
+Version 1.x is needed in order for OpenID v2 to work.
 
-This plugin has a configuration option. You can set `--openidsignup`
-to the url of a third-party site where users can sign up for an OpenID. If
-it's set, the signin page will link to that site.
-
-This plugin supports the
-[myopenid.com affiliate program](http://myopenid.com/affiliate_welcome),
-which can be used to help users sign up for an OpenID and log into your
-site in a single, unified process. When you create the affiliate, specify a
-login url like `http://example.com/ikiwiki.cgi?do=continue`. Once the
-affiliate is created, set `openidsignup` to point to the affiliate's signup
-url.
+The [[!cpan LWPx::ParanoidAgent]] perl module is used if available, for
+added security. Finally, the [[!cpan Crypt::SSLeay]] perl module is needed

 This plugin is enabled by default, but can be turned off if you want to
 only use some other form of authentication, such as [[passwordauth]].
+
+## options
+
+These options do not normally need to be set, but can be useful in
+certain setups.
+
+* `openid_realm` can be used to control the scope of the openid request.
+  It defaults to the `cgiurl` (or `openid_cgiurl` if set); only allowing
+  ikiwiki's [[CGI]] to authenticate. If you have multiple ikiwiki instances,
+  or other things using openid on the same site, you may choose to put them
+  all in the same realm to improve the user's openid experience. It is an
+  url pattern, so can be set to eg "http://*.example.com/"
+
+* `openid_cgiurl` can be used to cause a different than usual `cgiurl`
+  to be used when doing openid authentication. The `openid_cgiurl` must
+  point to an ikiwiki [[CGI]], and it will need to match the `openid_realm`
+  to work.
+
+## troubleshooting
+
+See [[plugins/openid/troubleshooting]] for a number of issues that may
+need to be addressed when setting up ikiwiki to accept OpenID logins reliably.
+
+## delegation
+
+This plugin does not take care of doing the "server" part of the
+OpenID protocol, only the "client" part. In other words, it allows
+users to login to your site through OpenID, but is not in itself an
+OpenID provider.
+
+It is possible, however, to use your Ikiwiki site as a delegation
+point to another OpenID provider. For this, use the
+[[ikiwiki/directive/meta/]] directive with the `openid` parameter.
