 ## Methods
 
-### `net.request`
+The `net` module has the following methods:
+
+### `net.request(options)`
+
+Create a `ClientRequest` instance using the provided `options` object.
+
+Returns `ClientRequest`
 
 ## Class: ClientRequest
 
+### `new ClientRequest(options)`
+
+* `options` Object or String - If `options` is a String, it is interpreted as the request URL. If it is an object, it is expected to fully specify an HTTP request via the following properties:
+  * `method` String (optional) - The HTTP request method. Defaults to the GET method.
+  * `url` String (required) - The request URL. Must be provided in the absolute form with the protocol scheme specified as http or https.
+  * `protocol` String (optional) - The protocol scheme in the form 'scheme:'. Current supported values are 'http:' or 'https:'. Defaults to 'http:'.
+  * `host` String (optional) - The server host provided as a concatenation of a hostname and a port number 'hostname:port'
+  * `hostname` String (optional) - The server host name.
+  * `port` Integer (optional) - The server's listening port number.
+  * `path` String (optional) - The path part of the request URL. 
+  
+`options` properties `protocol`, `host`, `hostname`, `port` and `path` strictly follow the Node.js model as described in the [URL](https://nodejs.org/api/url.html) module.
+
 ### Instance Events
 
 #### Event: 'response'
 
+Returns:
+
+* `response` IncomingMessage - An object representing the HTTP response message.
+
 #### Event: 'login'
 
+Returns:
+
+* `callback` Function
+
+Emitted when an authenticating proxy is asking for user credentials.
+
+The `callback` function is expected to be called back with user credentials:
+
+* `usrename` String
+* `password` String
+
+Providing empty credentials will cancel the request.
+
 #### Event: 'finish'
 
+Emitted just after the last chunk of the `request`'s data has been written into the `request` object.
+
 #### Event: 'abort'
 
+Emitted when the `request` is aborted. The abort event will not be fired if the `request` is already closed.
+
 #### Event: 'error'
 
+Returns:
+
+* `error` Error - an error object providing some information about the failure.
+
+Emitted when the `net` module fails to issue a network request. Typically when the `request` object emits an error event, a close event will subsequently follow and no response object will be provided.
+
 #### Event: 'close'
 
+Emitted as the last event in the HTTP request-response transaction. The close event indicates that no more events will be emitted on either the `request` or `response` objects.
+
 ### Instance Methods
 
 #### `request.setHeader(name, value)`
 
+* `name` String - An extra header name.
+* `value` String - An extra header value.
+
+Adds an extra HTTP header. The header name will issued as it is without lowercasing.
+
 #### `request.getHeader(name)`
 
+* `name` String - Specify an extra header name.
+
+Returns String - The value of a previously set extra header name.
+
 #### `request.removeHeader(name)`
 
-#### `request.write(chunk, [encoding], [callback])`
+* `name` String - Specify an extra header name.
+
+Removes a previously set extra header name. 
+
+#### `request.write(chunk, [encoding, callback])`
+
+* `chunk` String or Buffer - A chunk of the request body' data. If it is a string, it is converted into a Buffer object using the specified encoding.
+* `encoding` String (optional) - Used to convert string chunks into Buffer objects. Defaults to 'utf-8'.
+* `callback` Function (optional) - Called after the write operation ends.
+
+Adds a chunk of data to the request body. Generally, the first write operation causes the request headers to be issued on the wire. 
+After the first write operation, it is not allowed to add or remove a custom header.
 
-#### `request.end(chunk, [encoding], [callback])`
+#### `request.end([chunk, encoding, callback])`
+
+* `chunk` String or Buffer (optional)
+* `encoding` String (optional)
+* `callback` Function (optional)
+
+Sends the last chunk of the request data. Subsequent write or end operations will not be allowed. The finish event is emitted just after the end operation.
 
 #### `request.abort()`
 
+Cancels an ongoing HTTP transaction. If the request has already closed, the abort operation will have no effect. 
+Otherwise an ongoing event will emit abort and close events. Additionally, if there is an ongoing response object,
+it will emit the aborted event.
