+# Contributing to dash-core-components
+
+## Getting Started
+
+Refer to the [readme](README.md) for installation and development instructions.
+
+## Contributions
+
+[Dash Core Components][] consist of pluggable components for creating interactive user interfaces. For generic HTML5 elements, see [Dash HTML Components][]. Contributions are welcome! This repository's open [issues][] are a good place to start. Another way to contribute is to [write your own components][] using the [Dash Components Archetype][].
+
+## Coding Style
+
+Please lint any additions to react components with `npm run lint`. Rules defined in [.eslintrc](.eslintrc) are inherited from [`dash-components-archetype`](https://github.com/plotly/dash-components-archetype)'s [eslintrc-react.json][]
+
+## Pull Request Guidelines
+
+Use the [GitHub flow][] when proposing contributions to this repository (i.e. create a feature branch and submit a PR against the master branch).

+## Publishing New Components/Features
+
+For now, multiple steps are necessary for publishing to NPM and PyPi,
+respectively. TODO:
+[#5](https://github.com/plotly/dash-components-archetype/issues/5) will roll up publishing steps into one workflow.
+
+1. Create a pull request and tag the Plotly team (`@plotly/dash`) as well as an appropriate reviewer (frequent [contributors][] are a safe bet).
+2. After a review has been done and your changes have been approved, create a prerelease and comment in the PR. Version numbers should follow [semantic versioning][]. To create a prerelease:
+    * Add `rc1` to `version.py` (`./dash_core_components/version.py`) e.g. `0.13.0rc1`
+    * Add `-rc1` to `package.json` e.g. `0.13.0-rc1`
+    * Update the `unpkg` link in `./dash_core_components/__init__.py`, replacing `__version__` with your release candidate (e.g. `"0.13.0-rc1"`)
+    * Run `npm run publish-all`.
+        - If needed, ask @chriddyp to get NPM / PyPi package publishing access.
+        - If the `publish-all` script fails on the `twine` command, try running
+            ```sh
+            twine upload dist/dash_core_components-X.X.X.tar.gz # where xx.x.x is the version number
+            ```
+3. Comment in the PR with the prerelease version
+4. Update the top-level comment to include info about how to install, a summary of the changes, and a simple example. For a good example, see the [Confirmation Modal component][].
+    * This makes it easier for a community member to come in and try it out. As more folks review, it's harder to find the installation instructions deep in the PR
+    * Keep this top-level comment updated with installation instructions (e.g. the `pip install` command)
+5. Make a post in the [Dash Community Forum][]
+    * Title it `":mega: Announcement! New <Your Feature> - Feedback Welcome"`
+    * In the description, link to the PR and any relevant issue(s)
+    * Pin the topic so that it appears at the top of the forum for two weeks
+    * For a good example, see the [Confirmation Modal announcement][]
