+# Creating a release
+
+Only collaborators in npm for node-addon-api can create releases.
+If you want to be able to do releases ask one of the existing
+collaborators to add you.  If necessary you can ask the build
+Working Group who manages the Node.js npm user to add you if
+there are no other active collaborators.
+
+These are the steps to follow to create a new release:
+
+* Open an issue in the node-addon-api repo documenting
+  the intent to create a new release.  Give people some
+  time to comment or suggest PRs that should land first.
+
+* Validate all tests pass by running npm test on master.
+
+* Use https://ci.nodejs.org/view/x%20-%20Abi%20stable%20module%20API/job/node-test-node-addon-api/
+  to validate tests pass for latest 9, 8, 6, 4 releases
+  (note there are still some issues on smartos and
+   windows in the testing).
+
+* Update the version in package.json appropriately.
+
+* Add any new contributors to the "contributors" section in
+  the package.json
+
+* Do a clean checkout of node-add-api.
+
+* Login and then run `npm publish`.
+
+* Create a release in github (look at existing releases for an example).
+
+* Validate that you can run `npm install node-addon-api` successfully
+  and that the correct version is installed.
+
+* Comment on the issue opened in the first step that the
+  release has been created and close the issue.
+
+* Tweet that the release has been created.
