+# 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 sascha.muellner@gmail.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.

+
+## Requirements
+
+The latest version of MultiUser requires:
+
+- Swift 5+
+- iOS 13+
+- Xcode 11+
+
+## Installation
+
+### Swift Package Manager
+Using SPM add the following to your dependencies
+
+``` 'MultiUser', 'master', 'https://github.com/smuellner/MultiUser-for-swift.git' ```
+
+### CocoaPods
+Using CocoaPods add the following to your Podfile:
+
+```pod 'MultiUser-for-Swift', '~> 1.0.1'```
+
+### What?
+This is a **Swift** package with support for iOS/macOS/tvOS/watchOS that allows to store user releated data for multiple users of an application.
+
+### How to use?
+
+#### Service
+
+The **UserService** cares for the whole user handling and implements the **UserServiceProtocol**.
+To allow for access throughout your application place the **UserService** in a shared instance like the Application Delegate or use a dependency injection framework like **Swinject**.
+
+
+```swift
+
+let userService = UserService()
+
+
+```
+
+
+#### User
+
+Retrieve a list of all users:
+
+```swift
+
+let userService = UserService()
+
+print(userService.allUsers)
+//
+
+```
+
+
+Create a user
+
+```swift
+
+let user = userService.createUser()
+user.username = ""
+user.firstname = ""
+user.lastname = ""
+
+userService.saveUser(user)
+
+```
