+# Releasing
+
+We use [Changesets](https://github.com/changesets/changesets) to version and release our packages.
+
+When you're ready to cut a release, start by versioning the packages:
+
+```
+npx changeset version
+```
+
+This will consume the changesets in [`.changeset`](../.changeset) and update the [changelog](../CHANGELOG.md) and [`package.json`](../package.json):
+
+```
+% git status --short
+ M CHANGELOG.md
+ M package.json
+```
+
+Based on the versions implications declared by the changesets, the package version will be updated to the next patch, minor, or major:
+
+```diff
+   "name": "@browserbasehq/stagehand",
+-  "version": "1.3.0",
++  "version": "1.3.1",
+```
+
+Since we updated the `package.json`, we should also update the lockfile ([`package-lock.json`](../package-lock.json)) for tidiness:
+
+```
+npm install
+```
+
+Now the lockfile should be updated:
+
+```
+% git status --short
+ M CHANGELOG.md
+ M package-lock.json
+ M package.json
+```
+
+The diff will look something like this:
+
+```diff
+ {
+   "name": "@browserbasehq/stagehand",
+-  "version": "1.3.0",
++  "version": "1.3.1",
+   "lockfileVersion": 3,
+   "requires": true,
+   "packages": {
+     "": {
+       "name": "@browserbasehq/stagehand",
+-      "version": "1.3.0",
++      "version": "1.3.1",
+```
+
+At this point we're ready to commit our changes.
+It's probably a good idea to have some consistency around the name of this commit message:
+
+```
+git commit -am 'Version Packages'
+```
+
+Ok, now it's time to publish the release.
+Before we do, we have to build the artifacts that comprise the tarball.
+Let's clean our working directory first so that we don't accidentally include anything in the tarball that shouldn't be there:
+
+```
+% git clean -fxd -e .env
+Removing dist/
+Removing lib/dom/build/
+Removing node_modules/
+```
+
+Let's reinstall dependencies and build the artifacts:
+
+```
+npm install && npm run build
+```
+
+Now we're ready to publish to NPM. You have to be logged in via the `npm` CLI and have to be part of the `@browserbasehq` org:
+
+```
+npx changeset publish
+```
+
+Congratulations! You just published a new version of `@browserbasehq/stagehand`. 🤘
+
+In the process of publishing, Changesets created an [annotated git tag](https://git-scm.com/book/en/v2/Git-Basics-Tagging):
+
+```
+🦋  Creating git tag...
+🦋  New tag:  v1.3.1
+```
+
+Let's push the commit and tag to GitHub for posterity:
+
+```
+git push --follow-tags
+```
