+le-challenge-memory
+===================
+
+An in-memory strategy for node-letsencrypt for setting, retrieving,
+and clearing ACME challenges issued by the ACME server
+
+* Safe to use on ephemeral services (i.e. AWS)
+* DO NOT use with node cluester (i.e. letsencrypt-cluster)
+
+Install
+-------
+
+```bash
+npm install --save le-challenge-standalone@2.x
+```
+
+Usage
+-----
+
+```bash
+var leChallenge = require('le-challenge-standalone').create({
+, debug: false
+});
+
+var LE = require('letsencrypt');
+
+LE.create({
+  server: LE.stagingServerUrl
+, challenge: leChallenge
+});
+```
+
+NOTE: If you request a certificate with 6 domains listed,
+it will require 6 individual challenges.
+
+Exposed Methods
+---------------
+
+For ACME Challenge:
+
+* `set(opts, domain, key, val, done)`
+* `get(defaults, domain, key, done)`
+* `remove(defaults, domain, key, done)`
+
+For node-letsencrypt internals:
+
+* `getOptions()` returns the user supplied options, if any (no effect)
