 1.  Identify the third party scripts on the web that have the greatest performance cost.
 1.  Give developers the information they need to make informed decisions about which third parties to include on their sites.
 1.  Incentivize responsible third party script behavior.
+1.  Make this information accessible and useful.
 
 ## Methodology
 
 [HTTP Archive](https://httparchive.org/) is an inititiave that tracks how the web is built. Twice a month, ~4 million sites are crawled with [Lighthouse](https://github.com/GoogleChrome/lighthouse) on mobile. Lighthouse breaks down the total script execution time of each page and attributes the execution to a URL. Using [BigQuery](https://cloud.google.com/bigquery/), this project aggregates the script execution to the origin-level and assigns each origin to the responsible entity.
 
+## NPM Module
+
+The entity classification data is available as an NPM module.
+
+```js
+const { getEntity } = require("third-party-web");
+const entity = getEntity("https://d36mpcpuzc4ztk.cloudfront.net/js/visitor.js");
+console.log(entity);
+//   {
+//     "name": "Freshdesk",
+//     "homepage": "https://freshdesk.com/",
+//     "categories": ["customer-success"],
+//     "domains": ["d36mpcpuzc4ztk.cloudfront.net"]
