+# Contributing Guidelines
+
+Contributions welcome!
+
+**Before spending lots of time on something, ask for feedback on your idea first!**
+
+Please search issues and pull requests before adding something new to avoid duplicating
+efforts and conversations.
+
+This project welcomes non-code contributions, too! The following types of contributions
+are welcome:
+
+- **Ideas**: participate in an issue thread or start your own to have your voice heard.
+- **Writing**: contribute your expertise in an area by helping expand the included docs.
+- **Copy editing**: fix typos, clarify language, and improve the quality of the docs.
+- **Formatting**: help keep docs easy to read with consistent formatting.
+
+## Code Style
+
+[![standard][standard-image]][standard-url]
+
+This repository uses [`standard`][standard-url] to maintain code style and consistency,
+and to avoid style arguments. `npm test` runs `standard` automatically, so you don't have
+to!
+
+[standard-image]: https://cdn.rawgit.com/feross/standard/master/badge.svg
+[standard-url]: https://standardjs.com
+
+## Project Governance
+
+Individuals making significant and valuable contributions are given commit-access to the
+project to contribute as they see fit. This project is more like an open wiki than a
+standard guarded open source project.
+
+### Rules
+
+There are a few basic ground-rules for contributors:
+
+1. **No `--force` pushes to master** or modifying history in any way. Rebasing and force pushing your own PR branch is fine.
+2. **Non-master branches** should be used for ongoing work.
+3. **Significant modifications** like API changes should be subject to a **pull request**
+   to solicit feedback from other contributors.
+4. **Pull requests** are *encouraged* for all contributions to solicit feedback, but left to
+   the discretion of the contributor.
+
+### Releases
+
+Declaring formal releases remains the prerogative of the project maintainer.
+
+### Changes to this arrangement
+
+This is an experiment and feedback is welcome! This document may also be subject to pull-
+requests or changes by contributors where you believe you have something valuable to add
+or change.
+
+## Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+- (a) The contribution was created in whole or in part by me and I have the right to
+  submit it under the open source license indicated in the file; or
+
+- (b) The contribution is based upon previous work that, to the best of my knowledge, is
+  covered under an appropriate open source license and I have the right under that license
+  to submit that work with modifications, whether created in whole or in part by me, under
+  the same open source license (unless I am permitted to submit under a different
+  license), as indicated in the file; or
+
+- (c) The contribution was provided directly to me by some other person who certified
+  (a), (b) or (c) and I have not modified it.
+
+- (d) I understand and agree that this project and the contribution are public and that a
+  record of the contribution (including all personal information I submit with it,
+  including my sign-off) is maintained indefinitely and may be redistributed consistent
+  with this project or the open source license(s) involved.
+
+## Release Procedure
+
+### 1. Create a new version
+
+- Update `AUTHORS`
+
+  ```
+  npm run update-authors
+  ```
+
+  Commit if necessary. The commit message should be "authors".
+
+- Write the changelog
+
+  You can use `git log --oneline <last version tag>..HEAD` to get a list of changes.
+
+  Summarize them concisely in `CHANGELOG.md`. The commit  message should be "changelog".
+
+- Update the version
+
+  ```
+  npm version [major|minor|patch]
+  ```
+
+  This creates both a commit and a git tag.
+
+- Make a PR
+
+  Once the PR is reviewed, merge it:
+
+  ```
+  git push origin <branch-name>:master
+  ```
+
+  This makes it so that the commit hash on master matches the commit hash of the version tag.
+
+  Finally, run:
+
+  ```
+  git push --tags
+  ```
+
+### 2. Create the release binaries
+
+- On a Mac:
+
+  ```
+  npm run package -- darwin --sign
+  npm run package -- linux --sign
+  ```
+
+- On Windows, or in a Windows VM:
+
+  ```
+  npm run package -- win32 --sign
+  ```
+
+- Then, upload the release binaries to Github:
+
+  ```
+  npm run gh-release
+  ```
+
+  Follow the URL to a newly created Github release page. Manually upload the binaries from
+  `webtorrent-desktop/dist/`. Open the previous release in another tab, and make sure that you
+  are uploading the same set of files, no more, no less.
+
+### 3. Test it
+
+**This is the most important part.**
+
+ - Manually download the binaries for each platform from Github.
+
+  **Do not use your locally built binaries.** Modern OSs treat executables differently if they've
+  been downloaded, even though the files are byte for byte identical. This ensures that the
+  codesigning worked and is valid.
+
+- Smoke test WebTorrent Desktop on each platform.
+
+  See Smoke Tests below for details. Open DevTools
+  on Windows and Mac, and ensure that the auto updater is running. If the auto updater does not
+  run, users will successfully auto update to this new version, and then be stuck there forever.
+
+### 4. Ship it
+
+- Update the website
+
+  Create a pull request in [webtorrent.io](https://github.com/webtorrent/webtorrent.io). Update
+  `config.js`, updating the desktop app version.
+
+  As soon as this PR is merged, Jenkins will automatically redeploy the WebTorrent website, and
+  hundreds of thousands of users around the world will start auto updating. **Merge with care.**
+
+## Smoke Tests
+
+Before a release, check that the following basic use cases work correctly:
+
+1. Click "Play" to stream a built-in torrent (e.g. Sintel)
+  - Ensure that seeking to undownloaded region works and plays immediately.
+  - Ensure that sintel.mp4 gets downloaded to `~/Downloads`.
+
+2. Check that the auto-updater works
+  - Open the console and check for the line "No update available" to indicate
+
+3. Add a new .torrent file via drag-and-drop.
+  - Ensure that it gets added to the list and starts downloading
+
+4. Remove a torrent from the client
+  - Ensure that the file is removed from `~/Downloads`
+
+5. Create and seed a new a torrent via drag-and-drop.
+  - Ensure that the torrent gets created and seeding begins.

-
-  ```
-  npm run gh-release
-  ```
-
-  Follow the URL to a newly created Github release page. Manually upload the binaries from
-  `webtorrent-desktop/dist/`. Open the previous release in another tab, and make sure that you
-  are uploading the same set of files, no more, no less.
-
-### 3. Test it
-
-**This is the most important part.**
-
- - Manually download the binaries for each platform from Github.
-
-  **Do not use your locally built binaries.** Modern OSs treat executables differently if they've
-  been downloaded, even though the files are byte for byte identical. This ensures that the
-  codesigning worked and is valid.
-
-- Smoke test WebTorrent Desktop on each platform.
-
-  See Smoke Tests below for details. Open DevTools
-  on Windows and Mac, and ensure that the auto updater is running. If the auto updater does not
-  run, users will successfully auto update to this new version, and then be stuck there forever.
-
-### 4. Ship it
-
-- Update the website
-
-  Create a pull request in [webtorrent.io](https://github.com/webtorrent/webtorrent.io). Update
-  `config.js`, updating the desktop app version.
-
-  As soon as this PR is merged, Jenkins will automatically redeploy the WebTorrent website, and
-  hundreds of thousands of users around the world will start auto updating. **Merge with care.**
-
-## Smoke Tests
-
-Before a release, check that the following basic use cases work correctly:
-
-1. Click "Play" to stream a built-in torrent (e.g. Sintel)
-  - Ensure that seeking to undownloaded region works and plays immediately.
-  - Ensure that sintel.mp4 gets downloaded to `~/Downloads`.
-
-2. Check that the auto-updater works
-  - Open the console and check for the line "No update available" to indicate that the auto-updater is working.
-
-3. Add a new .torrent file via drag-and-drop.
-  - Ensure that it gets added to the list and starts downloading.
-
-4. Remove a torrent from the client
-  - Ensure that the file is removed from `~/Downloads`
-
-5. Create and seed a new a torrent via drag-and-drop.
-  - Ensure that the torrent gets created and seeding begins.
