-## Install
+---
 
-`npm install ftp-srv --save`
+> Looking for v2? Check the [v2](#v2) branch.
 
-`yarn add ftp-srv`
+# Installation
 
-## Usage
-- [Options](#options)
-- [Events](#events)
-- [File System](#file-system)
-
-```js
-const FtpSvr = require('ftp-srv');
-const ftpServer = new FtpSvr([url], { [options] ... });
-
-ftpServer.on('...', (data, resolve, reject) => { ... })
-
-ftpServer.listen()
-.then(() => { ... });
+```
+$ yarn install
 ```
 
-### Options
-__url__ : `ftp://127.0.0.1:21`
-> Host and port to listen on and make passive connections to.  
-Set the hostname to "0.0.0.0" to fetch the external IP automatically: `ftp://0.0.0.0:21`
-
-__pasv_range__ : `22`
-> Minimum port or range to use for passive connections.  
-Provide either a starting integer (`1000`) or a range (`1000-2000`).
-
-__anonymous__ : `false`
-> Set whether a valid username or password combination is required.  
-If true, will not require the `PASS` command to be sent for login.
-
-__blacklist__ : `[]`
-> Commands listed will not be allowed.  
-`['RMD', 'RNFR', 'RNTO']`
-
-__whitelist__ : `[]`
-> If set, no other commands are allowed except for those explicitly listed.  
-`['USER', 'PASS', 'PWD']`
-
-__file_format__ : `ls`
-> Format to use for [file stat](https://nodejs.org/api/fs.html#fs_class_fs_stats) responses (such as with the `LIST` command).  
-Possible values:  
- `ls` : [bin/ls format](https://cr.yp.to/ftp/list/binls.html)  
- `ep` : [Easily Parsed LIST format](https://cr.yp.to/ftp/list/eplf.html)  
- `function` : pass in your own format function, returning a string:  
-`function (fileStats) { ... }`
-
-__log__ : `bunyan`
-> A [bunyan logger](https://github.com/trentm/node-bunyan) instance.
-
-### Events
-All events emit the same structure: `({data object}, resolve, reject)`
-
-__login__ : `{connection, username, password}`
-> Occurs after `PASV` (or `USER` if `options.anonymous`)  
-```
-resolve({
-  fs, // [optional] custom file system class
-  cwd, // [optional] initial working directory (if not using custom file system),
-  blacklist, // [optional] commands to forbid for this connection only
-  whitelist // [optional] if set, only these commands are allowed for this connection only
-})
-```  
-
-### File System
-The file system can be overridden to use your own custom class. This an allow for interacting with files without actually writing them.  
-
-*Anytime a [file stat](https://nodejs.org/api/fs.html#fs_class_fs_stats) object is used, it must have added `name` property with the file's name.*
