+## Directory Structure
+
+Code is organised into modules which contain one-or-more components. This a great way to ensure maintainable code by encapsulation of behavior logic. A component is basically a self contained app usually in a single file or a folder with each concern as a file: style, template, specs, e2e, and component class. Here's how it looks:
+```

+<!--[CN_GITFLOW_PROCESS]-->
+# GitFlow Development Process
+
+This project uses the [GitHub Flow](https://guides.github.com/introduction/flow/index.html) workflow.
+
+## Create a branch
+When you're working on a project, you're going to have a bunch of different features or ideas in progress at any given time – some of which are ready to go, and others which are not. Branching exists to help you manage this workflow.
+
+When you create a branch in your project, you're creating an environment where you can try out new ideas. Changes you make on a branch don't affect the `master` branch, so you're free to experiment and commit changes, safe in the knowledge that your branch won't be merged until it's ready to be reviewed by someone you're collaborating with.
+
+###ProTip
+
+Branching is a core concept in Git, and the entire GitHub Flow is based upon it. There's only one rule: anything in the `master` branch is always deployable.
+
+Because of this, it's extremely important that your new branch is created off of `master` when working on a feature or a fix. Your branch name should be descriptive (e.g., `refactor-authentication`, `user-content-cache-key`, `make-retina-avatars`), so that others can see what is being worked on.
+
+## Add commits
+Once your branch has been created, it's time to start making changes. Whenever you add, edit, or delete a file, you're making a commit, and adding them to your branch. This process of adding commits keeps track of your progress as you work on a feature branch.
+
+Commits also create a transparent history of your work that others can follow to understand what you've done and why. Each commit has an associated commit message, which is a description explaining why a particular change was made. Furthermore, each commit is considered a separate unit of change. This lets you roll back changes if a bug is found, or if you decide to head in a different direction.
+
+###ProTip
+
+Commit messages are important, especially since Git tracks your changes and then displays them as commits once they're pushed to the server. By writing clear commit messages, you can make it easier for other people to follow along and provide feedback.
+
+## Open a pull request
+
+Pull Requests initiate discussion about your commits. Because they're tightly integrated with the underlying Git repository, anyone can see exactly what changes would be merged if they accept your request.
+
+You can open a Pull Request at any point during the development process: when you have little or no code but want to share some screenshots or general ideas, when you're stuck and need help or advice, or when you're ready for someone to review your work. By using GitHub's @mention system in your Pull Request message, you can ask for feedback from specific people or teams, whether they're down the hall or ten time zones away.
+
+###ProTip
+
+Pull Requests are useful for contributing to open source projects and for managing changes to shared repositories. If you're using a Fork & Pull Model, Pull Requests provide a way to notify project maintainers about the changes you'd like them to consider. If you're using a Shared Repository Model, Pull Requests help start code review and conversation about proposed changes before they're merged into the `master` branch.
+
+## Discuss and review your code
+Once a Pull Request has been opened, the person or team reviewing your changes may have questions or comments. Perhaps the coding style doesn't match project guidelines, the change is missing unit tests, or maybe everything looks great and props are in order. Pull Requests are designed to encourage and capture this type of conversation.
+
+You can also continue to push to your branch in light of discussion and feedback about your commits. If someone comments that you forgot to do something or if there is a bug in the code, you can fix it in your branch and push up the change. GitHub will show your new commits and any additional feedback you may receive in the unified Pull Request view.
+
+###ProTip
+
+Pull Request comments are written in Markdown, so you can embed images and emoji, use pre-formatted text blocks, and other lightweight formatting.
+
+## Merge to `master`
+
+Once your PR has passed any the integration tests and received approval to merge, it is time to merge your code into the `master` branch.
+
+Once merged, Pull Requests preserve a record of the historical changes to your code. Because they're searchable, they let anyone go back in time to understand why and how a decision was made.
+
+###ProTip
+
+By incorporating certain keywords into the text of your Pull Request, you can associate issues with code. When your Pull Request is merged, the related issues are also closed. For example, entering the phrase Closes #32 would close issue number 32 in the repository. For more information, check out our help article.

+<!--[CN_CHANGING_BUILD_TOOL_CONFIG]-->
+## Changing build-tool configuration
+
+There are 3 ways you can change the build-tool configuration for this project:
+
+1. BEST: Modify the Confit configuration file ([confit.yml](confit.yml)) by hand, then re-run `yo confit` and tell it to use the existing configuration.
+1. OK: Re-run `yo confit` and provide new answers to the questions. **Confit will attempt to overwrite your existing configuration (it will prompt for confirmation), so make sure you have committed your code to a source control (e.g. git) first**.
+  There are certain configuration settings which can **only** be specified by hand, in which case the first approach is still best.
+1. RISKY: Modify the generated build-tool config by hand. Be aware that if you re-run `yo confit` it will attempt to overwrite your changes. So commit your changes to source control first.
+
+Additionally, the **currently-generated** configuration can be extended in the following ways:
+
+- The task configuration is defined in [package.json](package.json). It is possible to change the task definitions to add your own sub-tasks.
+You can also use the `pre...` and `post...` script-name prefixes to run commands before (pre) and after (post) the generated commands.
+
+- The `entryPoint.entryPoints` string in [confit.yml](confit.yml) is designed to be edited manually. It represents the starting-point(s) of the application (like a `main()` function). A NodeJS application has one entry point. E.g. `src/index.js`

+## Overview
+`ftp-srv` is a modern and extensible FTP server designed to be simple yet configurable.
+
+## Features
+- Extensible [file systems](#file-system) per connection
+- Passive and active transfers
+- [Explicit](https://en.wikipedia.org/wiki/FTPS#Explicit) & [Implicit](https://en.wikipedia.org/wiki/FTPS#Implicit) TLS connections
+
+## Install
+`npm install ftp-srv --save`  
+
+## Usage
+
+```js
+// Quick start
+
+const FtpSvr = require('ftp-srv');
+const ftpServer = new FtpSvr('ftp://0.0.0.0:9876', { options ... });
+
+ftpServer.on('login', (data, resolve, reject) => { ... });
+...
+
+ftpServer.listen()
+.then(() => { ... });
+```
+
+## API
+
+### `new FtpSrv(url, [{options}])`
+#### url
+[URL string](https://nodejs.org/api/url.html#url_url_strings_and_url_objects) indicating the protocol, hostname, and port to listen on for connections.  
+Supported protocols:
+- `ftp` Plain FTP
+- `ftps` Implicit FTP over TLS  
+
+_Note:_ The hostname must be the external IP address to accept external connections. Setting the hostname to `0.0.0.0` will automatically set the external IP.  
+__Default:__ `"ftp://127.0.0.1:21"`
+
+#### options
+
+##### `pasv_range`
+A starting port (eg `8000`) or a range (eg `"8000-9000"`) to accept passive connections.  
+This range is then queried for an available port to use when required.  
+__Default:__ `22`
+
+##### `greeting`
+A human readable array of lines or string to send when a client connects.  
+__Default:__ `null`
+
+##### `tls`
+Node [TLS secure context object](https://nodejs.org/api/tls.html#tls_tls_createsecurecontext_options) used for implicit (`ftps` protocol) or explicit (`AUTH TLS`) connections.  
+__Default:__ `false`
+
+##### `anonymous`
+If true, will allow clients to authenticate using the username `anonymous`, not requiring a password from the user.  
+Can also set as a string which allows users to authenticate using the username provided.  
+The `login` event is then sent with the provided username and `@anonymous` as the password.  
+__Default:__ `false`
+
+##### `blacklist`
+Array of commands that are not allowed.  
+Response code `502` is sent to clients sending one of these commands.  
+__Example:__ `['RMD', 'RNFR', 'RNTO']` will not allow users to delete directories or rename any files.  
+__Default:__ `[]`
+
+##### `whitelist`
+Array of commands that are only allowed.  
+Response code `502` is sent to clients sending any other command.  
+__Default:__ `[]`
+
+##### `file_format`
+Sets the format to use for file stat queries such as `LIST`.  
+__Default:__ `"ls"`  
+__Allowable 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 () {}` A custom function returning a format or promise for one.
+    - Only one argument is passed in: a node [file stat](https://nodejs.org/api/fs.html#fs_class_fs_stats) object with additional file `name` parameter
+
+##### `log`
+A [bunyan logger](https://github.com/trentm/node-bunyan) instance. Created by default.
+
+## Events
+
+The `FtpSvr` class extends the [node net.Server](https://nodejs.org/api/net.html#net_class_net_server). Some custom events can be resolved or rejected, such as `login`.
+
+### `login`
+```js
+on('login', {connection, username, password}, resolve, reject) => { ... }
+```
+
+Occurs when a client is attempting to login. Here you can resolve the login request by username and password.
+
+`connection` [client class object](src/connection.js)  
+`username` string of username from `USER` command  
+`password` string of password from `PASS` command  
+`resolve` takes an object of arguments:
+- `fs`
+  - Set a custom file system class for this connection to use.
+  - See [File System](#file-system) for implementation details.
+- `root`
+  - If `fs` is not provided, this will set the root directory for the connection.
+  - The user cannot traverse lower than this directory.
+- `cwd`
+  - If `fs` is not provided, will set the starting directory for the connection
+  - This is relative to the `root` directory.
+- `blacklist`
+  - Commands that are forbidden for only this connection
+- `whitelist`
+  - If set, this connection will only be able to use the provided commands
+
+`reject` takes an error object
+
+### `client-error`
+```js
+on('client-error', {connection, context, error}) => { ... }
+```
+
+Occurs when an error arises in the client connection.
+
+`connection` [client class object](src/connection.js)  
+`context` string of where the error occured  
+`error` error object
+
+## Supported Commands
+
+See the [command registry](src/commands/registration) for a list of all implemented FTP commands.
+
+## File System
+The default [file system](src/fs.js) can be overwritten to use your own implementation.  
+This can allow for virtual file systems, and more.  
+Each connection can set it's own file system based on the user.  
+
+The default file system is exported and can be extended as needed:
+```js
+const {FtpSrv, FileSystem} = require('ftp-srv');
+
+class MyFileSystem extends FileSystem {
+  constructor() {
+    super(...arguments);
+  }
+
+  get(fileName) {
+    ...
+  }
+}
+```
+
+Custom file systems can implement the following variables depending on the developers needs:

-## Overview
-`ftp-srv` is a modern and extensible FTP server designed to be simple yet configurable.
-
-## Features
- Extensible [file systems](#file-system) per connection
- Passive and active transfers
- [Explicit](https://en.wikipedia.org/wiki/FTPS#Explicit) & [Implicit](https://en.wikipedia.org/wiki/FTPS#Implicit) TLS connections
- Promise based API
-
-## Install
-`npm install ftp-srv --save`
-
-## Usage
-
-```js
-// Quick start
-
-const FtpSrv = require('ftp-srv');
-const ftpServer = new FtpSrv({ options ... });
-
-ftpServer.on('login', (data, resolve, reject) => { ... });
-...
-
-ftpServer.listen()
-.then(() => { ... });
-```
-
-## API
-
-### `new FtpSrv({options})`
-#### url
-[URL string](https://nodejs.org/api/url.html#url_url_strings_and_url_objects) indicating the protocol, hostname, and port to listen on for connections.
-Supported protocols:
- `ftp` Plain FTP
- `ftps` Implicit FTP over TLS
-
-_Note:_ The hostname must be the external IP address to accept external connections. `0.0.0.0` will listen on any available hosts for server and passive connections.  
-__Default:__ `"ftp://127.0.0.1:21"`
-
-#### `pasv_url`
-The hostname to provide a client when attempting a passive connection (`PASV`). This defaults to the provided `url` hostname.
-
-_Note:_ If set to `0.0.0.0`, this will automatically resolve to the external IP of the box.  
-__Default:__ `"127.0.0.1"`
-
-#### `pasv_min`
-Tne starting port to accept passive connections.  
-__Default:__ `1024`
-
-#### `pasv_max`
-The ending port to accept passive connections.  
-The range is then queried for an available port to use when required.  
-__Default:__ `65535`
-
-#### `greeting`
-A human readable array of lines or string to send when a client connects.  
-__Default:__ `null`
-
-#### `tls`
-Node [TLS secure context object](https://nodejs.org/api/tls.html#tls_tls_createsecurecontext_options) used for implicit (`ftps` protocol) or explicit (`AUTH TLS`) connections.  
-__Default:__ `false`
-
-#### `anonymous`
-If true, will allow clients to authenticate using the username `anonymous`, not requiring a password from the user.  
-Can also set as a string which allows users to authenticate using the username provided.  
-The `login` event is then sent with the provided username and `@anonymous` as the password.  
-__Default:__ `false`
-
-#### `blacklist`
-Array of commands that are not allowed.  
-Response code `502` is sent to clients sending one of these commands.  
-__Example:__ `['RMD', 'RNFR', 'RNTO']` will not allow users to delete directories or rename any files.  
-__Default:__ `[]`
-
-#### `whitelist`
-Array of commands that are only allowed.  
-Response code `502` is sent to clients sending any other command.  
-__Default:__ `[]`
-
-#### `file_format`
-Sets the format to use for file stat queries such as `LIST`.  
-__Default:__ `"ls"`  
-__Allowable 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 () {}` A custom function returning a format or promise for one.
-    - Only one argument is passed in: a node [file stat](https://nodejs.org/api/fs.html#fs_class_fs_stats) object with additional file `name` parameter
-
-#### `log`
-A [bunyan logger](https://github.com/trentm/node-bunyan) instance. Created by default.
-
-#### `timeout`
-Sets the timeout (in ms) after that an idle connection is closed by the server  
-__Default:__ `0`
-
-## CLI
-
-`ftp-srv` also comes with a builtin CLI.
-
-```bash
-$ ftp-srv [url] [options]
-```
-
-```bash
-$ ftp-srv ftp://0.0.0.0:9876 --root ~/Documents
-```
-
-#### `url`
-
-Set the listening URL.
-
-Defaults to `ftp://127.0.0.1:21`
-
-#### `--root` / `-r`
-
-Set the default root directory for users.
-
-Defaults to the current directory.
-
-#### `--credentials` / `-c`
-
-Set the path to a json credentials file.
-
-Format:
-
-```js
-[
-  {
-    "username": "...",
-    "password": "...",
-    "root": "..." // Root directory
-  },
-  ...
-]
-```
-
-#### `--username`
-
-Set the username for the only user. Do not provide an argument to allow anonymous login.
-
-#### `--password`
-
-Set the password for the given `username`.
-
-## Events
-
-The `FtpSrv` class extends the [node net.Server](https://nodejs.org/api/net.html#net_class_net_server). Some custom events can be resolved or rejected, such as `login`.
-
-### `login`
-```js
-ftpServer.on('login', ({connection, username, password}, resolve, reject) => { ... });
-```
-
-Occurs when a client is attempting to login. Here you can resolve the login request by username and password.
-
-`connection` [client class object](src/connection.js)  
-`username` string of username from `USER` command  
-`password` string of password from `PASS` command  
-`resolve` takes an object of arguments:  
- `fs`
-  - Set a custom file system class for this connection to use.
-  - See [File System](#file-system) for implementation details.
- `root`
-  - If `fs` is not provided, this will set the root directory for the connection.
-  - The user cannot traverse lower than this directory.
- `cwd`
-  - If `fs` is not provided, will set the starting directory for the connection
-  - This is relative to the `root` directory.
- `blacklist`
-  - Commands that are forbidden for only this connection
- `whitelist`
-  - If set, this connection will only be able to use the provided commands
-
-`reject` takes an error object
-
-### `client-error`
-```js
-ftpServer.on('client-error', ({connection, context, error}) => { ... });
-```
-
-Occurs when an error arises in the client connection.
-
-`connection` [client class object](src/connection.js)  
-`context` string of where the error occurred  
-`error` error object
-
-### `RETR`
-```js
-connection.on('RETR', (error, filePath) => { ... });
-```
-
-Occurs when a file is downloaded.
-
-`error` if successful, will be `null`  
-`filePath` location to which file was downloaded
-
-### `STOR`
-```js
-connection.on('STOR', (error, fileName) => { ... });
-```
-
-Occurs when a file is uploaded.
-
-`error` if successful, will be `null`  
-`fileName` name of the file that was uploaded
-
-### `RNTO`
-```js
-connection.on('RNTO', (error, fileName) => { ... });
-```
-
-Occurs when a file is renamed.
-
-`error` if successful, will be `null`  
-`fileName` name of the file that was renamed
-
-## Supported Commands
-
-See the [command registry](src/commands/registration) for a list of all implemented FTP commands.
-
-## File System
-The default [file system](src/fs.js) can be overwritten to use your own implementation.  
-This can allow for virtual file systems, and more.  
-Each connection can set it's own file system based on the user.  
-
-The default file system is exported and can be extended as needed:  
-```js
-const {FtpSrv, FileSystem} = require('ftp-srv');
-
-class MyFileSystem extends FileSystem {
-  constructor() {
-    super(...arguments);
-  }
-
-  get(fileName) {
-    ...
-  }
-}
-```
-

-# Migration Guide - v2 to v3
-
-The `FtpServer` constructor has been changed to only take one object option. Combining the two just made sense.
-
-### From:
-
-```js
-const server = new FtpServer('ftp://0.0.0.0:21');
-```
-
-### To:
-
-```js
-const server = new FtpServer({
-  url: 'ftp://0.0.0.0:21'
-});
-```
-
----
-
-The `pasv_range` option has been changed to separate integer variables: `pasv_min`, `pasv_max`.
-
-### From:
-
-```js
-const server = new FtpServer(..., {
-  pasv_range: '1000-2000'
-});
-```
-
-### To:
-
-```js
-const server = new FtpServer({
-  pasv_min: 1000,
-  pasv_max: 2000
-})
-```
-
----
-
-The default passive port range has been changed to `1024` - `65535`

-  AUTHENTICATION/SECURITY MECHANISM (AUTH)
-
-  The argument field is a Telnet string identifying a supported
-  mechanism.  This string is case-insensitive.  Values must be
-  registered with the IANA, except that values beginning with "X-"
-  are reserved for local use.
-
-  If the server does not recognize the AUTH command, it must respond
-  with reply code 500.  This is intended to encompass the large
-  deployed base of non-security-aware ftp servers, which will
-  respond with reply code 500 to any unrecognized command.  If the
-  server does recognize the AUTH command but does not implement the
-  security extensions, it should respond with reply code 502.
-
-  If the server does not understand the named security mechanism, it
-  should respond with reply code 504.
-
-  If the server is not willing to accept the named security
-  mechanism, it should respond with reply code 534.
-
-  If the server is not able to accept the named security mechanism,
-  such as if a required resource is unavailable, it should respond
-  with reply code 431.
-
-  If the server is willing to accept the named security mechanism,
-  but requires security data, it must respond with reply code 334.
-
-  If the server is willing to accept the named security mechanism,
-  and does not require any security data, it must respond with reply
-  code 234.
-
-  If the server is responding with a 334 reply code, it may include
-  security data as described in the next section.
-
-  Some servers will allow the AUTH command to be reissued in order
-  to establish new authentication.  The AUTH command, if accepted,
-  removes any state associated with prior FTP Security commands.
-  The server must also require that the user reauthorize (that is,
-  reissue some or all of the USER, PASS, and ACCT commands) in this
-  case (see section 4 for an explanation of "authorize" in this
-  context).

-  PROTECTION BUFFER SIZE (PBSZ)
-
-  The argument is a decimal integer representing the maximum size,
-  in bytes, of the encoded data blocks to be sent or received during
-  file transfer.  This number shall be no greater than can be
-  represented in a 32-bit unsigned integer.
-
-  This command allows the FTP client and server to negotiate a
-  maximum protected buffer size for the connection.  There is no
-  default size; the client must issue a PBSZ command before it can
-  issue the first PROT command.
-
-  The PBSZ command must be preceded by a successful security data
-  exchange.
-
-  If the server cannot parse the argument, or if it will not fit in
-  32 bits, it should respond with a 501 reply code.
-
-  If the server has not completed a security data exchange with the
-  client, it should respond with a 503 reply code.
-
-  Otherwise, the server must reply with a 200 reply code.  If the
-  size provided by the client is too large for the server, it must
-  use a string of the form "PBSZ=number" in the text part of the
-  reply to indicate a smaller buffer size.  The client and the
-  server must use the smaller of the two buffer sizes if both buffer
-  sizes are specified.
