+Protect your site with OpenID
+=============================
+You have the option of enabling OpenID authentication to help secure your
+pastes on phorkie.
+Set the ``$GLOBALS['phorkie']['auth']`` values in the
+``data/config.php`` file as desired.
+
+There are two different types of security you can apply.
+First, you can restrict to one of three ``securityLevels``:
+
+- completely open (``0``)
+- protection of write-enabled functions such as add, edit, etc. (``1``)
+- full site protection (``2``)
+
+Additionally, you can restrict your site to ``listedUsersOnly``.
+You will need to add the individual OpenID urls to the
+``$GLOBALS['phorkie']['auth']['users']`` variable.
+
+
+Get information about paste editors
+===================================
+Phorkie stores the user's OpenID or IP address (when not logged in) when
+a paste is edited.
+It is possible to get this information for each single commit::
+
+ // IP / OpenID for the latest commit
+ $ git notes --ref=identity show
+ 127.0.0.1
+
+ // show IP / OpenID for a given commit
+ $ git notes --ref=identity show 29f82a
+ http://cweiske.de/
+
+
+Notifications via webhooks
+==========================
+Depending on how you use phorkie, it might be nice to notify some other service
+when pastes are added or updated.
+Phorkie contains a simply mechanism to post data to a given URL which
+you can then use as needed.
+
+The data are json-encoded POSTed to the URLs contained in the
+``$GLOBALS['phorkie']['cfg']['webhooks']`` setting array, with
+a MIME type of ``application/vnd.phorkie.webhook+json``::
+
+ {
+ 'event': 'create',
+ 'author': {
+ 'name':'Anonymous',
+ 'email': 'anonymous@phorkie',
+ },
+ 'repository': {
+ 'name': 'webhooktest',
+ 'url': 'http://example.org/33',
+ 'description': 'webhooktest',
+ 'owner': {
+ 'name': 'Anonymous',
+ 'email': 'anonymous@phorkie',
+ }
+ }
+ }
+
+The event may be ``create``, ``edit`` or ``delete``.
