 ### letsencrypt (the library)
 
+There are **NO DEFAULTS**. A number of **constants** (such as LE.stagingServerUrl and LE.configDir)
+are exported for your convenience, but all required options must be specified by the library invoking the call.

+Open an issue if you need a variable for something that isn't there yet.

 Examples
 ========
 
+The simplest example of setting up a webserver appropriately is probably `letsencrypt-cli` (~120 lines of code):

+* [letsencrypt-cli//lib/standalone.js](https://github.com/Daplie/node-letsencrypt-cli/blob/master/lib/standalone.js)

+Similary, `letsencrypt-cli`'s usage of `le.register()` is fairly simple (~75 lines of code):

 ### One-Time Registration
 
 Register a 90-day certificate manually, on a whim
 
+**Note**: We've been running a fast development cycle and this example may be out of date.
+The API *shouldn't* have changed much but, we probably need to come back and update it.
