+# 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 the project team at hello@lord.io. The project team will review and investigate all complaints, and will respond in a way that it deems 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][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

+
+Slate helps you create beautiful, intelligent, responsive API documentation.
+
+
+
+The example above was created with Slate. Check it out at slatedocs.github.io/slate .
+
+Features
+------------
+
+* **Clean, intuitive design** — With Slate, the description of your API is on the left side of your documentation, and all the code examples are on the right side. Inspired by [Stripe's](https://stripe.com/docs/api) and [PayPal's](https://developer.paypal.com/webapps/developer/docs/api/) API docs. Slate is responsive, so it looks great on tablets, phones, and even in print.
+
+* **Everything on a single page** — Gone are the days when your users had to search through a million pages to find what they wanted. Slate puts the entire documentation on a single page. We haven't sacrificed linkability, though. As you scroll, your browser's hash will update to the nearest header, so linking to a particular point in the documentation is still natural and easy.
+
+* **Slate is just Markdown** — When you write docs with Slate, you're just writing Markdown, which makes it simple to edit and understand. Everything is written in Markdown — even the code samples are just Markdown code blocks.
+
+* **Write code samples in multiple languages** — If your API has bindings in multiple programming languages, you can easily put in tabs to switch between them. In your document, you'll distinguish different languages by specifying the language name at the top of each code block, just like with GitHub Flavored Markdown.
+
+* **Out-of-the-box syntax highlighting** for [over 100 languages](https://github.com/rouge-ruby/rouge/wiki/List-of-supported-languages-and-lexers), no configuration required.
+
+* **Automatic, smoothly scrolling table of contents** on the far left of the page. As you scroll, it displays your current position in the document. It's fast, too. We're using Slate at TripIt to build documentation for our new API, where our table of contents has over 180 entries. We've made sure that the performance remains excellent, even for larger documents.
+
+* **Let your users update your documentation for you** — By default, your Slate-generated documentation is hosted in a public GitHub repository. Not only does this mean you get free hosting for your docs with GitHub Pages, but it also makes it simple for other developers to make pull requests to your docs if they find typos or other problems. Of course, if you don't want to use GitHub, you're also welcome to host your docs elsewhere.
+
+* **RTL Support** Full right-to-left layout for RTL languages such as Arabic, Persian (Farsi), Hebrew etc.
+
+Getting started with Slate is super easy! Simply press the green "use this template" button above and follow the instructions below. Or, if you'd like to check out what Slate is capable of, take a look at the [sample docs](https://slatedocs.github.io/slate/).
