-## 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.**
-
