 # Release Process
 
-Releases are mostly automated using
-[release-it](https://github.com/release-it/release-it/) and
-[lerna-changelog](https://github.com/lerna/lerna-changelog/).
+Releases in this repo are mostly automated using [release-plan](https://github.com/embroider-build/release-plan/). Once you label all your PRs correctly (see below) you will have an automatically generated PR that updates your CHANGELOG.md file and a `.release-plan.json` that is used prepare the release once the PR is merged.
 
 ## Preparation
 
-Since the majority of the actual release process is automated, the primary
-remaining task prior to releasing is confirming that all pull requests that
-have been merged since the last release have been labeled with the appropriate
-`lerna-changelog` labels and the titles have been updated to ensure they
-represent something that would make sense to our users. Some great information
-on why this is important can be found at
-[keepachangelog.com](https://keepachangelog.com/en/1.0.0/), but the overall
-guiding principle here is that changelogs are for humans, not machines.
-
-When reviewing merged PR's the labels to be used are:
-
-- breaking - Used when the PR is considered a breaking change.
-- enhancement - Used when the PR adds a new feature or enhancement.
-- bug - Used when the PR fixes a bug included in a previous release.
-- documentation - Used when the PR adds or updates documentation.
-- internal - Used for internal changes that still require a mention in the
-  changelog/release notes.
-
-## Release
-
-Once the prep work is completed, the actual release is straight forward:
-
-- First, ensure that you have installed your projects dependencies:
-
-```sh
-pnpm install
-```
+Since the majority of the actual release process is automated, the remaining tasks before releasing are: 
 
-- Second, ensure that you have obtained a
-  [GitHub personal access token][generate-token] with the `repo` scope (no
-  other permissions are needed). Make sure the token is available as the
-  `GITHUB_AUTH` environment variable.
+-  correctly labeling **all** pull requests that have been merged since the last release
+-  updating pull request titles so they make sense to our users
 
-  For instance:
-
-  ```bash
-  export GITHUB_AUTH=abc123def456
-  ```
-
-[generate-token]: https://github.com/settings/tokens/new?scopes=repo&description=GITHUB_AUTH+env+variable
-
-- Test that the release will succeed. Make sure your `origin` git remote is using SSH (or you are authorized via your protocol of choice)
-
-  ```sh
-  npx release-it --dry-run
-  ```
-
-  If you've changed your origin from https to ssh, be sure to set the upstream:
+Some great information on why this is important can be found at [keepachangelog.com](https://keepachangelog.com/en/1.1.0/), but the overall
+guiding principle here is that changelogs are for humans, not machines.
 
-  ```sh 
-  git push --set-upstream origin main
-  ```
+When reviewing merged PR's the labels to be used are:
 
-- And last (but not least 😁) do your release.
+* breaking - Used when the PR is considered a breaking change.
+* enhancement - Used when the PR adds a new feature or enhancement.
+* bug - Used when the PR fixes a bug included in a previous release.
+* documentation - Used when the PR adds or updates documentation.
+* internal - Internal changes or things that don't fit in any other category.
 
-  ```sh
-  npx release-it
-  ```
+**Note:** `release-plan` requires that **all** PRs are labeled. If a PR doesn't fit in a category it's fine to label it as `internal`
 
-[release-it](https://github.com/release-it/release-it/) manages the actual
-release process. It will prompt you to to choose the version number after which
-you will have the chance to hand tweak the changelog to be used (for the
-`CHANGELOG.md` and GitHub release), then `release-it` continues on to tagging,
-pushing the tag and commits, etc.
+## Release
 
-If prompted for a username/password by `release-it`, the `GITHUB_AUTH` environment
-variable was not detected. Enter your username, and use your personal access token
-as the password, and the release should succeed.
+Once the prep work is completed, the actual release is straight forward: you just need to merge the open [Plan Release](https://github.com/embroider-build/addon-blueprint/pulls?q=is%3Apr+is%3Aopen+%22Prepare+Release%22+in%3Atitle) PR
