-## Changesets
-
-Changesets are a way to manage changes to the codebase that are not yet released. Here are a few things to keep in mind when you create a changeset:
-
-- Following semantic versioning, select between: major, minor and patch
-  - **MAJOR** version when you make incompatible API changes
-  - **MINOR** version when you add functionality in a backwards compatible manner
-  - **PATCH** version when you make backwards compatible bug fixes.
-- When describing the change, try to answer the following:
-  - **WHAT** the change is
-  - **WHY** the change was made

-### Preparing a Release
+## Release Please
 
-After every PR with a changeset is merged, a changesets CI job will create or update a "Version Packages" PR, which contains the release version and information about the changes.
+This repo uses [Release Please](https://github.com/googleapis/release-please) to manage releases. Do not run `pnpm changeset` or add changeset files for releases.
 
-### How to Release
+Release Please determines the next release from Conventional Commit messages on `main`. Because PR titles are linted, use a Conventional Commit title that describes the user-visible impact of the change:
 
-1. Approve or request approval to merge the "Version Packages" PR.
-2. Merge the "Version Packages" PR.
-3. This will trigger the release workflow, automatically releasing a new version and pushing a tag for the version. Check the [release view](https://github.com/smartcontractkit/mcms/releases) to confirm the latest release.
+- `feat: add support for new deployment workflow` for backwards-compatible features
+- `fix: handle missing workflow artifacts` for backwards-compatible bug fixes
+- `perf: reduce datastore lookup latency` for performance improvements
+- `feat!: remove deprecated workflow input` or a commit body with `BREAKING CHANGE:` for incompatible API changes
+
+Other types such as `docs`, `test`, `ci`, `chore`, `build`, `style`, and `refactor` are allowed, but they are hidden from the changelog by the current Release Please configuration and usually do not create a release by themselves.
+
+When writing the PR title and description, make it clear:
+
+- **WHAT** the change is
+- **WHY** the change was made
+- Whether the change is breaking or requires downstream action
+
+## Semantic Versioning
+
+Release Please follows semantic versioning when choosing the next version:
+
+- **MAJOR** version when you make incompatible API changes
+- **MINOR** version when you add functionality in a backwards-compatible manner
+- **PATCH** version when you make backwards-compatible bug fixes
+
+## Preparing a Release
+
+The `release-please` workflow runs after changes are merged to `main`. When Release Please finds releasable changes, it opens or updates a release PR that includes the version bump, changelog updates, and `.release-please-manifest.json` changes.
+
+## How to Release
+
+1. Review the Release Please PR and confirm the changelog and version are correct.
+2. Approve or request approval to merge the Release Please PR.
+3. Merge the Release Please PR into `main`.
+4. The `release-please` workflow will create the GitHub release and push the version tag automatically.
