 1. To kick off a release run `npm run release-draft *.*.*|major|minor|patch` on the main branch. This will run the [release draft script](https://github.com/mongodb-js/vscode/blob/main/scripts/release-draft.js) which creates a new tag for the release.
-1. When that tag has been created, a GitHub action for building the extension is automatically started: https://github.com/mongodb-js/vscode/blob/main/.github/workflows/test-and-build.yaml This creates the `.vsix` artifact for that release version and creates a draft GitHub release, with the .vsix artifact attached. At this point you can look in https://github.com/mongodb-js/vscode/releases and see the draft release.
-1. Now is a good time to download the built artifact and ensure it works smoothly.
-1. Update the [release notes](https://github.com/mongodb-js/vscode/releases) in github, documenting user facing changes. Once you’re happy with the changes you can publish the release.
