 JSON Browse is build using [`next.js`](https://github.com/zeit/next.js/), [`styled-components`](https://github.com/styled-components/styled-components) and
 easily deployable using [`now`](https://zeit.co/now/).
 
+## Dependencies
+
+JSON Browse's all external requests are proxied with [jsonbrowse-proxy](https://github.com/jorilallo/jsonbrowse-proxy)
+which only adds CORS headers (no logging is performed). Local requests are made directly so calling `localhost`
+is possible.
