+## paystack-node
+
+A Nodejs API wrapper for [Paystack](https://paystack.co/).
+
+### Installation
+
+```
+npm install paystack-node
+```
+
+### Usage
+
+```js
+// Require the library
+var paystack = require('./index')('secret_key');
+
+// Make a call to the resource/method
+// paystack.{resource}.{method}
+paystack.customer.list(function(error, body) {
+  console.log(error);
+  console.log(body);
+});
+```
+
+The resource method accepts an optional callback as the last argument. The callback returns two JSON objects - `error`, which will be null for successful calls, and `body`, the response from the API call.
+
+For resource methods that use POST or PUT, the JSON body can be passed as the first argument.
+
+```js
+paystack.plan.create({
+  name: 'API demo',
+  amount: 10000,
+  interval: 'monthly'
+},function(error, body) {
+  console.log(error);
+  console.log(body);
+});
+```
+
+For GET, you can pass the required ID as string and optional parameters as an optioal object argument.
+
+```js
+paystack.plan.get(90, function(error, body) {
+  console.log(error);
+  console.log(body);
+});
+```
+
+```js
+paystack.transactions.list({
+  perPage: 20
+}, function(error, body) {
+  console.log(error);
+  console.log(body);
+});
+```
+
