+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at info@jyxon.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

+# Ulrack Command
+
+This package supplies command routing for PHP applications.
+
+## Installation
+
+To install the package run the following command:
+
+```
+composer require ulrack/command
+```
+
+## Usage
+
+### [Command configuration](src/Dao/CommandConfiguration.php)
+Command configuration is done through an object.
+The main command configuration should be an empty instance of this class.
+This main object can then be supplied to the [router](src/Common/Router/RouterInterface.php).
+
+All sub-commands can be added to their respective command configuration instance.
+This can be infinitely deep.
+All command configuration instances have the `no-interaction` and `help` flag configured by default.
+Sub-commands of a parent command can be executed by separating them by a space.
+
+### [Router](src/Component/Router/CommandRouter.php)
+The command router performs the routing of commands.
+It creates an instance of the `service` and executes it.
+This service object must implement the [CommandInterface](src/Common/Command/CommandInterface.php).
+
+To find out more about how services work, see the `ulrack/services` package.
+
+### Input and Output
+The [input](src/Component/Command/Input.php) is an object which provides the input to the implementation of the command.
+The [output](src/Component/Command/Output.php) provides a standard set of methods for displaying output to the user of the application.
+The input instance can be created by providing the `$argv` to the `create` method of the [InputFactory](src/Factory/InputFactory.php).
+
+### Standard commands
+The package contains two standard commands for displaying a command [list](src/Command/ListCommandsCommand.php)
+and showing a command [explanation](src/Command/HelpCommand.php).
+
+## Examples
+
+An example can be found in the [examples](examples) directory.
+
+## Change log
+
+Please see [CHANGELOG](CHANGELOG.md) for more information on what has changed recently.
+
+## Contributing
+
+Please see [CONTRIBUTING](CONTRIBUTING.md) and [CODE_OF_CONDUCT](CODE_OF_CONDUCT.md) for details.
