+
+Login to your account at:
+https://account.gandi.net/
+
+Under the Security section, click the link next to 'Production API key' to generate a token.
+
+Usage
+First you create an instance with your credentials:
+
+var dns01 = require('acme-dns-01-gandi').create({
+	baseUrl: 'https://dns.api.gandi.net/api/v5/', // default
+	token: 'xxxx'
+});
+Then you can use it with any compatible ACME library, such as Greenlock.js or ACME.js.
+
+Greenlock.js
+var Greenlock = require('greenlock-express');
+var greenlock = Greenlock.create({
+	challenges: {
+		'dns-01': dns01
+		// ...
+	}
+});
+See Greenlock Express and/or Greenlock.js documentation for more details.
+
+ACME.js
+// TODO
+See the ACME.js for more details.
+
+Build your own
+There are only 5 methods:
+
+init(config)
+zones(opts)
+set(opts)
+get(opts)
+remove(opts)
+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');
+	});
