 =============
+
+Node library for querying the [Clearbit](https://clearbit.co) business intelligence APIs. Currently supports:
+
+* [Person API](https://clearbit.co/docs#person-api)
+* [Company API](https://clearbit.co/docs#company-api)
+
+# Setup
+```bash
+$ npm install clearbit
+```
+```js
+var clearbit = require('clearbit')('api_key');
+// or 
+var Client   = require('clearbit').Client;
+var clearbit = new Client({key: 'api_key'});
+```
+
+## Person
+
+#### `Person.find(options)` -> `Promise`
+  * `email` *String*: The email address to look up **(required)**
+  * `webhook_id` *String*: Custom identifier for the webhook request
+  * `subscribe` *Boolean*: Set to `true` to subscribe to the changes
+  * `company` *Boolean*: Set to `true` to include a company lookup on the email’s domain name in the response
+  * `stream` *Boolean*: Set to `true` to use the [streaming API](https://clearbit.co/docs?shell#streaming) instead of webhooks 
+
+```js
+var Person = clearbit.Person;
+Person.find({email: 'email@domain.com'})
+  .then(function (person) {
+    if (!person.pending()) {
+      console.log('Name: ', person.name.fullName);
+    }
+  })
+  .catch(Person.NotFoundError, function (err) {
+    console.log(err); // Person could not be found
+  })
+  .catch(function (err) {
+    console.log('Bad/invalid request, unauthorized, Clearbit error, or failed request');
+  });
+```
+
+#### `person.pending()` -> `Boolean`
+If Clearbit responds with a `202` status indicating that lookup has been queued, `person.pending` returns `true`.
+
+## Company
+
+#### `Company.find(options)` -> `Promise`
+  * `domain` *String*: The company domain to look up **(required)**
+  * `webhook_id` *String*: Custom identifier for the webhook request
+  * `stream` *Boolean*: Set to `true` to use the [streaming API](https://clearbit.co/docs?shell#streaming) instead of webhooks 
+
+```js
+var Company = clearbit.Company;
+Company.find({domain: 'www.uber.com'})
+  .then(function (company) {
+    if (!company.pending()) {
+      console.log('Name: ', company.name);
+    }
+  })
+  .catch(Company.NotFoundError, function (err) {
+    console.log(err); // Company could not be found
+  })
+  .catch(function (err) {
+    console.log('Bad/invalid request, unauthorized, Clearbit error, or failed request');
+  });
+```
+
+#### `company.pending()` -> `Boolean`
+If Clearbit responds with a `202` status indicating that lookup has been queued, `company.pending` returns `true`.
