 Assuming you have a [local version of PostHog](https://posthog.com/docs/developing-locally) running, you can run `python3 example.py` to see the library in action.
 
-### Releasing Versions
-
-Updates are released automatically using GitHub Actions when `version.py` is updated on `master`. After bumping `version.py` in `master` and adding to `CHANGELOG.md`, the [release workflow](https://github.com/PostHog/posthog-python/blob/master/.github/workflows/release.yaml) will automatically trigger and deploy the new version.

-If you need to check the latest runs or manually trigger a release, you can go to [our release workflow's page](https://github.com/PostHog/posthog-python/actions/workflows/release.yaml) and dispatch it manually, using workflow from `master`.

 ### Testing changes locally with the PostHog app
 
 You can run `make prep_local`, and it'll create a new folder alongside the SDK repo one called `posthog-python-local`, which you can then import into the posthog project by changing pyproject.toml to look like this:

 This'll let you build and test SDK changes fully locally, incorporating them into your local posthog app stack. It mainly takes care of the `posthog -> posthoganalytics` module renaming. You'll need to re-run `make prep_local` each time you make a change, and re-run `uv sync --active` in the posthog app project.

+## Releasing
+
+This repository uses [Sampo](https://github.com/bruits/sampo) for versioning, changelogs, and publishing to crates.io.
+
+1. When making changes, include a changeset: `sampo add`
+2. Create a PR with your changes and the changeset file
+3. Add the `release` label and merge to `main`
+4. Approve the release in Slack when prompted — this triggers version bump, crates.io publish, git tag, and GitHub Release
+
+You can also trigger a release manually via the workflow's `workflow_dispatch` trigger (still requires pending changesets).
