+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).

-| [letsencrypt](https://github.com/Daplie/node-letsencrypt) (library)
+An extremely simple reference implementation
-| [letsencrypt-cli](https://github.com/Daplie/letsencrypt-cli)
+of an ACME (Let's Encrypt) dns-01 challenge strategy.

-le-challenge-dns
+This generic implementation can be adapted to work with any node.js ACME client,
-================
+although it was built for [Greenlock](https://git.rootprojects.org/root/greenlock-express.js)
-
+and [ACME.js](https://git.rootprojects.org/root/acme-v2.js).
-A dns-based strategy for node-letsencrypt for setting, retrieving,
-and clearing ACME DNS-01 challenges issued by the ACME server
-
-It creates a subdomain record for `_acme-challenge` wich `challenge`
-to be tested by the ACME server.
 
 ```
 _acme-challenge.example.com   TXT   xxxxxxxxxxxxxxxx    TTL 60
 ```
 
-* Safe to use with node cluster
+- Prints the ACME challenge DNS Host and DNS Key Authorization Digest to the terminal
-* Safe to use with ephemeral services (Heroku, Joyent, etc)
+  - (waits for you to hit enter before continuing)
+- Let's you know when the challenge as succeeded or failed, and is safe to remove.
 
-Install
+Other ACME Challenge Reference Implementations:
--------
+
+- [acme-http-01-cli](https://git.rootprojects.org/root/acme-http-01-cli.js.git)
+- [acme-http-01-fs](https://git.rootprojects.org/root/acme-http-01-webroot.js.git)
+- [**acme-dns-01-cli**](https://git.rootprojects.org/root/acme-dns-01-cli.js.git)
+
+## Install
 
 ```bash
-npm install --save le-challenge-dns@2.x
+npm install --save acme-dns-01-cli@3.x
 ```
 
-Usage
+If you have `greenlock@v2.6` or lower, you'll need the old `le-challenge-dns@2.x` instead.
------
 
-```bash
+## Usage
-var leChallengeDns = require('le-challenge-dns').create({
-  email: 'john.doe@example.com'
-, refreshToken: '...'
-, ttl: 60
 
-, debug: false
+```js
-});
+var Greenlock = require('greenlock');
 
-var LE = require('letsencrypt');
+Greenlock.create({
-
+  challenges: {
-LE.create({
+    'http-01': require('acme-http-01-fs'),
-  server: LE.stagingServerUrl                               // Change to LE.productionServerUrl in production
+    'dns-01': require('acme-dns-01-cli').create({ debug: true }),
-, challengeType: 'dns-01'
+    'tls-alpn-01': require('acme-tls-alpn-01-cli')
-, challenges: {
-    'dns-01': leChallengeDns
   }
-, approvedDomains: [ 'example.com' ]
+  // ...
 });
 ```
 
+You can also switch between different implementations by
+overwriting the default with the one that you want in `approveDomains()`:
+
+```js
+function approveDomains(opts) {
+  // ...
+  if (!opts.challenges) { opts.challenges = {}; }
+  opts.challenges['dns-01'] = acmeDns01Cli;
+
+  return Promise.resolve({ ... });
+}
+```
+
 NOTE: If you request a certificate with 6 domains listed,
 it will require 6 individual challenges.
 
-Exposed Methods
+## Exposed (Promise) Methods
----------------
 
 For ACME Challenge:
 
-* `set(opts, domain, challange, keyAuthorization, done)`
+- `set(opts)`
-* `get(defaults, domain, challenge, done)`
+- `remove(opts)`
-* `remove(defaults, domain, challenge, done)`
 
-Note: `get()` is a no-op for `dns-01` and although `dns-01` does not use `keyAuthorization`,
+The `dns-01` strategy supports wildcards (whereas `http-01` does not).
-it must be passed in as `null` to keep the correct method signature.
 
-For node-letsencrypt internals:
+The options object has whatever options were set in `approveDomains()`
+as well as the `challenge`, which looks like this:
 
-* `getOptions()` returns the internal defaults merged with the user-supplied options
+```json
-* `loopback(defaults, domain, challange, keyAuthorization, done)` should test, by external means, that the ACME server's challenge server will succeed
+{
-* `test(opts, domain, challange, keyAuthorization, done)` runs set, loopback, remove, loopback
+  "challenge": {
+    "identifier": { "type": "dns", "value": "example.com" },
+    "wildcard": true,
+    "altname": "*.example.com",
+    "type": "dns-01",
+    "token": "xxxxxx",
+    "keyAuthorization": "xxxxxx.abc123",
+    "dnsHost": "_acme-challenge.example.com",
+    "dnsAuthorization": "xyz567",
+    "expires": "1970-01-01T00:00:00Z"
+  }
+}
+```
+
+For greenlock.js internals:
+
+- `options` stores the internal defaults merged with the user-supplied options
+
+Optional:
+
+- `get(limitedOpts)`
+
+Note: Typically there wouldn't be a `get()` for DNS because the NameServer (not Greenlock) answers the requests.
+It could be used for testing implementations, but that's about it.
+(though I suppose you could implement it if you happen to run your DNS and webserver together... kinda weird though)
+
+If there were an implementation of Greenlock integrated directly into
+a NameServer (which currently there is not), it would probably look like this:
+
+```json
+{
+  "challenge": {
+    "type": "dns-01",
+    "identifier": { "type": "dns", "value": "example.com" },
+    "token": "abc123",
+    "dnsHost": "_acme-challenge.example.com"
+  }
+}
