+https-proxy-agent
+================
+### An HTTP(s) proxy `http.Agent` implementation for HTTPS
+
+This module provides an `http.Agent` implementation that connects to a specified
+HTTP or HTTPS proxy server, and can be used with the built-in `https` module.
+
+Specifically, this `Agent` implementation connects to an intermediary "proxy"
+server and issues the [CONNECT HTTP method][CONNECT], which tells the proxy to
+open a direct TCP connection to the destination server.
+
+Since this agent implements the CONNECT HTTP method, it also works with other
+protocols that use this method when connecting over proxies (i.e. WebSockets).
+See the "Examples" section below for more.
+
+Examples
+--------
+
+#### `https` module example
+
+```ts
+import * as https from 'https';
+import { HttpsProxyAgent } from 'https-proxy-agent';
+
+const agent = new HttpsProxyAgent('http://168.63.76.32:3128');
+
+https.get('https://example.com', { agent }, (res) => {
+  console.log('"response" event!', res.headers);
+  res.pipe(process.stdout);
+});
+```
+
+#### `ws` WebSocket connection example
+
+```ts
+import WebSocket from 'ws';
+import { HttpsProxyAgent } from 'https-proxy-agent';
+
+const agent = new HttpsProxyAgent('http://168.63.76.32:3128');
+const socket = new WebSocket('ws://echo.websocket.org', { agent });
+
+socket.on('open', function () {
+  console.log('"open" event!');
+  socket.send('hello world');
+});
+
+socket.on('message', function (data, flags) {
+  console.log('"message" event! %j %j', data, flags);
+  socket.close();
+});
+```
+
+API
+---
+
+### new HttpsProxyAgent(proxy: string | URL, options?: HttpsProxyAgentOptions)
+
+The `HttpsProxyAgent` class implements an `http.Agent` subclass that connects
+to the specified "HTTP(s) proxy server" in order to proxy HTTPS and/or WebSocket
+requests. This is achieved by using the [HTTP `CONNECT` method][CONNECT].
+
+The `proxy` argument is the URL for the proxy server.
+
+The `options` argument accepts the usual `http.Agent` constructor options, and
+some additional properties:
+
+ * `headers` - Object containing additional headers to send to the proxy server
+   in the `CONNECT` request.
+
