-# Preparing release notes
+Releasing is a 3-step process.
+
+# 1. Create a release branch
+
+1. Bump a version to the new `-post` version and land a `chore: cut vX.Y.Z-post version` commit
+  - `./utils/update_version.js vX.Y.Z-post`
+1. On your local machine, create a new branch `release-X.Y` based off the "cutting" commit and land a `chore: mark vX.Y.Z` in the local branch:
+  - `git checkout master`
+  - `git checkout -b release-X.Y`
+  - `./utils/update_version.js vX.Y`
+  - `npm run doc`
+  - `git commit -am 'chore: mark vX.Y.Z'`
+1. Push branch to the upstream
+  - `git push upstream release-X.Y`
+
+Once release branch is pushed, it's last commit will be picked up by our CI/CD:
+- make sure commit passes all the bots. If there are any failures, carefully inspect failures to see if these are flakes.
+- the [`publish_canary`](../../.github/workflows/publish_canary.yml) workflow will publish a `@next` version for the commit - this will be our **release candidate**. Go manually to it's page on NPM   to see what it looks like. Try installing locally.
+
+# 2. Prepare release notes
 
 1. Use ["draft new release tag"](https://github.com/microsoft/playwright/releases/new).
 1. Version starts with "v", e.g. "vX.Y.Z".
-1. Fill "Raw notes".
-    - `git fetch --tags upstream`
-    - `git log --pretty="%h - %s" $(git describe --tags --abbrev=0)..HEAD`
-1. Fill "Bug fixes".
-    - `git log $(git describe --tags --abbrev=0)..HEAD`
-    - Manually look for `#1234` references in commit messages.
-1. Fill "Current status".
-    - `node utils/print_versions.js`
-    - Copy tests status from [IsPlaywrightReady](https://aslushnikov.github.io/isplaywrightready/).
+1. Fill "Browser versions".
+    - `./utils/print_versions.js`
 1. Fill "Highlights" if any.
     - Be creative.
-1. Fill "Breaking API Changes" if any.
-    - `git diff $(git describe --tags --abbrev=0):docs/api.md docs/api.md`
 1. Fill "New APIs" if any.
-    - `git diff $(git describe --tags --abbrev=0):docs/api.md docs/api.md`
+    - `git diff $(git describe --tags $(git rev-list --tags --max-count=1)):docs/api.md docs/api.md`
+1. Fill "Breaking API Changes" if any.
+    - `git diff $(git describe --tags $(git rev-list --tags --max-count=1)):docs/api.md docs/api.md`
+1. Fill "Bug fixes".
+    - `git log $(git describe --tags $(git rev-list --tags --max-count=1))..HEAD`
+    - Manually look for `#1234` references in commit messages.
+1. Fill "Raw notes".
+    - `git fetch --tags upstream`
 1. When making links to the API, copy actual links from [GitHub](https://github.com/microsoft/playwright/blob/master/docs/api.md), and not from `api.md` source - these might be incorrect.
     - Before publishing, replace `blob/master/docs` with `blob/vX.Y.Z/docs` in all the links.
 1. Use "Save Draft", not "Publish".
 
-# Releasing to npm
+# 3. Publish Release
+
+1. Hit "publish release"
+
+Once release is published, the [`publish_release`](../../.github/workflows/publish_release.yml) will kick in and publish package version on NPM.
 
-1. Announce `PSA: release vX.Y.Z in progress. Please do not commit anything.`
-    - **Important**: no other commits should land in-between release commit and bump commit.
-1. Mark a new version.
-    - `node utils/update_version.js vX.Y.Z && npm run doc`.
-    - Send a PR titled `chore: mark version vX.Y.Z`.
-    - Make sure the PR passes all required checks and merge it.
-1. Publish to npm.
-    - `npm login`
-    - `utils/publish_all_packages.sh --release`
-1. Click 'Publish release' button on the prepared release notes.
-1. Mark post release.
-    - `node utils/update_version.js vX.Y.Z-post && npm run doc`.
-    - Merge a PR titled `chore: bump version to vX.Y.Z-post`.
-1. Announce `PSA: release vX.Y.Z is out.`
