+# 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, gender identity and expression, level of experience, 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 any of the code of conduct enforcers: [Andreas Mehlsen](mailto:[email protected]). 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.
+
+## Attribution
+
+This Code of Conduct is adapted from the Contributor Covenant, version 1.4, available at http://contributor-covenant.org/version/1/4/

+
+## What is this?
+
+A lightweight web component to trap focus within a DOM node. A focus trap ensures that `tab` and `shift + tab` keys will cycle through the focus trap's tabbable elements but will not leave the focus trap. This is great for making [accessible modals](https://www.w3.org/TR/wai-aria-practices/examples/dialog-modal/dialog.html). Check out the demo at [https://appnest-demo.firebaseapp.com/focus-trap/](https://appnest-demo.firebaseapp.com/focus-trap/).

+<img src="https://raw.githubusercontent.com/andreasbm/focus-trap/master/assets/demo.gif" width="400">
+
+**Features**
+
+* Does one things very very well - it traps the focus!
+* Pierces through the shadow roots when looking for focusable elements.
+* Works right out of the box (just add it to your markup)
+* Created using only vanilla js - no dependencies and framework agnostic!
+
+## Installation
+
+```javascript
+npm i @appnest/elements
+```
+
+## Usage
+
+Import `@appnest/elements` somewhere in your code and you're ready to go! Simply add the focus trap to your `html` and it'll be working without any more effort from your part.
+
+```html
+<focus-trap>
+  <button>Focus 1</button>
+  <button>Focus 2</button>
+  <button>Focus 3</button>
+  <button>Focus 4</button>
+  <button>Focus 5</button>
+</focus-trap>
+```
+
+## API
+
+The `focus-trap` element implements the following interface.
+
+```typescript
+interface IFocusTrap {
+  // Returns whether or not the focus trap is inactive.
+  inactive: boolean;
+
+  // Returns whether the focus trap currently has focus.
+  readonly focused: boolean;
+
+  // Focuses the first focusable element in the focus trap.
+  focusFirstElement: (() => void);
+
+  // Focuses the last focusable element in the focus trap.
+  focusLastElement: (() => void);
+
+  // Returns a list of the focusable children found within the element.
+  getFocusableChildren: (() => HTMLElement[]);
+}
+```
