 ## Adding a new icon
 
 It's easy to update or add a new icon because SVGs are automatically converted to React components. See [this documentation](./icons.md) for more information.

+# Contributing to the docs
+
+Thank you for your interest in contributing to the Orbit docs.
+It's efforts like yours that help keep our docs useful.
+
+## Table of Contents
+
+- [Location](#location)
+- [Running the docs locally](#running-the-docs-locally)
+- [Code style](#code-style)
+- [Prose style](#prose-style)
+
+## Location
+
+Our docs live mostly in two places.
+
+Basic details (props tables and such) for each component
+live in ReadMe files next to the component
+([example button ReadMe](https://github.com/kiwicom/orbit/blob/master/packages/orbit-components/src/Button/README.md)).
+
+More general guidelines and anything more complex lives in the [docs folder](../../docs),
+mostly in MDX files in the [documentation folder](../../docs/src/documentation).
+The structure of that folder matches the structure on [our built docs site](https://orbit.kiwi).
+
+## Running the docs locally
+
+Our docs site is based on [Gatsby](https://www.gatsbyjs.com/docs/).
+
+To run the site locally, start by cloning this repository.
+
+```shell
+git clone git@github.com:kiwicom/orbit.git
+```
+
+Navigate to the created directory.
+
+```shell
+cd orbit
+```
+
+Install all the necessary packages:
+
+```shell
+yarn
+```
+
+And start the site.
+
+```shell
+yarn dev:docs
+```
+
+Your site is now running at `http://localhost:8000`.
+
+Now you can make a change to a file in `docs/src/` (such as the docs in `docs/src/documentation/`)
+and your site updates automatically.
+
+## Code style
+
+To keep the files used to build our docs clear, we enforce standard Markdown code styling.
+
+We use [ESLint](https://eslint.org/) to enforce the style for our MDX files
+(just as we do for our JavaScript and TypeScript files).
+The specific rules are part of an extension for `eslint-plugin-mdx`,
+which you can find in [our ESLint settings](../../.eslintrc.js)
+(look for the rules that extend `plugin:mdx/recommended`).
+
+To fix any problems that can be fixed automatically,
+you can use an ESLint plugin for your IDE
+or run `yarn eslint:docs` from a terminal.
+
+### Line length
+
+In addition to the automatic fixes,
+we also prefer it when lines are no longer than 80 characters.
+This helps ensure the code is readable even in narrow spaces.
+
+But we don't enforce a strict limit to line length.
+If we did, automatic tools would rearrange lines at any change.
+Then reviews would be more difficult:
+`git diff` would show changes based on formatting rather than meaning.
+
+So we try to break lines at semantic breaks.
+This means having new sentences on new lines.
+This should help keep the differences for review about semantics,
+and not formatting.
+
+## Prose style
+
+In addition to the linting for code style in our docs,
+we also lint to ensure the docs follow our [style guide](https://orbit.kiwi/content/voice-tone/)
+as much as possible.
+
+For this, we use [Vale](https://docs.errata.ai/vale/about).
+Our specifics can be found in the [styles directory](../styles),
+with rules in the `Kiwi` folder and accepted spellings in [accept.txt](../styles/Vocab/Kiwi/accept.txt).
+
+To check your prose yourself, [install Vale](https://docs.errata.ai/vale/install).
+Or you can create a pull request
+and the Vale GitHub Action adds comments pointing out places that could be improved.
+
+The rules aren't perfect at detecting problems,
+so feel free to ignore any suggestions that seem wrong.
+
+## Checking links
+
+It's important for working documentation to have working links.
+
+To achieve this, after building the site, we check all built HTML for working links.
+Any broken link prevents a pull request from being merged.
+
+To check for yourself,
+run `yarn check-links` from a terminal at the root of this repository.
+Note that you need to have built the site first (run `yarn orbit-kiwi build`).
