+# BIN/IIN look up
+
+This module uses the https://binlist.net service to return information about a
+card by it's BIN number.
+
+## What is a BIN?
+
+The BIN is the first 4-8 characters of a card number: `xxxx xxxx ...`. You can
+pass any range of 4-8 numbers. More numbers will return more information.
+
+## Use
+
+```js
+// paid plan
+var b = require('binlookup')('my-api-key');
+
+// free plan
+var b = require('binlookup')();
+
+b('457173', function( err, data ){
+	if (err)
+		return console.error(err);
+
+	console.log(data);
+});
+```
+
+An example of the `data` variable:
+
+```js
+{
+	bin: "45717360",
+	brand: "VISA",
+	sub_brand: "DANKORT",
+	country_code: "DK",
+	country_name: "Denmark",
+	bank: "Jyske Bank",
+	card_type: "DEBIT",
+	card_category: "CLASSIC",
+	latitude: "56",
+	longitude: "10",
+	query_time: "352.309µs",
+}
+```
+
+If you're using their free plan, just leave out the api key.
