Then you can use it with any compatible ACME library, such as Greenlock.js or ACME.js.
## Greenlock.js
```js
var Greenlock = require('greenlock-express');
var greenlock = Greenlock.create({
challenges: {
'dns-01': dns01
// ...
}
});
```
See [Greenlock Express](https://git.rootprojects.org/root/greenlock-express.js) and/or [Greenlock.js](https://git.rootprojects.org/root/greenlock.js) documentation for more details.
## ACME.js
```js
// TODO
```
See the [ACME.js](https://git.rootprojects.org/root/acme-v2.js) for more details.
## Build your own
There are only 5 methods:
-`init(config)`
-`zones(opts)`
-`set(opts)`
-`get(opts)`
-`remove(opts)`
```js
dns01
.set({
identifier: { value: 'foo.example.co.uk' },
wildcard: false,
dnsZone: 'example.co.uk',
dnsPrefix: '_acme-challenge.foo',
dnsAuthorization: 'xxx_secret_xxx'
})
.then(function() {
console.log('TXT record set');
})
.catch(function() {
console.log('Failed to set TXT record');
});
```
See acme-dns-01-test for more implementation details.
