 Anonymous allows you to send messages anonymously as the bot. If 
-supybot.plugins.Anonymous.allowPrivateTarget is True, you can send messages in query too.

-One usage example is to identify the bot with NickServ if it fails to identify for some reason.
+## Usage examples
+
+### Identifying to NickServ
+
+One usage example is to identify the bot with NickServ if it fails to 
+identify for some reason.
+
+However this isn't recommended unless you don't use CertFP.
+
+#### SASL
+
+```
+@config networks.<network>.sasl.username NSACCOUNTNAME
+@config networks.<network>.sasl.password NSPASSWORD
+```
+
+Next time when your bot connects it should identify before connecting with 
+SASL.
+
+#### CertFP
+
+For help with generating the certificate [please see this page.](https://mkaysi.github.io/pages/external/identifying.html#certfp)
+
+When you have generated the certificate tell the bot to use it by either 
+of thse two commands (or both). The first tells the bot to use the 
+certificate everywhere and the second only on one network. If you run 
+the first, the second isn't necressary unless you have multiple 
+certificates.
+
+```
+@config protocols.irc.certfile /home/username/bot/bot.pem
+@config networks.<network>.certfile /home/username/bot/bot.pem
+```
+
+### Proving that you are the owner.
+
+When you ask for cloak/vhost for your bot, the network operators will 
+often ask you to prove that you own the bot. You can do this for example 
+with the following method:
+
+```
+@load Anonymous
+@config plugins.anonymous.requirecapability owner
+@config plugins.anonymous.allowprivatetarget True
+@anonymous say <operator nick> Hi, my owner is <your nick> :)
+```
+
+This
+* Loads the plugin.
+* Makes the plugin require that you are the owner
+    * If anyone could send private messages as the bot, they could also 
+    access network services.
+* Allows sending private messages
+* Sends message `Hi, my owner is <your nick> :)` to `operator nick`.
+    * Note that you won't see the messages that are sent to the bot.
