 Releasing the Provider
 ---------------------------
 
-As of Terraform 2.0.0 and 3.0.0, the provider is tied to Rancher minor releases but can be released 'out of band' within that minor version. For example, 4.0.0 will be released 1-2 weeks after Rancher 2.8.x and fixes and features in the 4.0.0 release will be supported for clusters provisioned via Terraform on Rancher 2.8.x. A critical bug fix can be released 'out of band' as 4.0.1 and backported to `release/v3` as 3.0.1. A new feature can also be released 'out of band' as 4.1.0 but not backported.
-
-The [RKE provider](https://github.com/rancher/terraform-provider-rke) should be released after every RKE or KDM release. For example, if upstream RKE 1.3.15 was released, bump the RKE version to 1.3.15 and release the provider.

 To release the provider
 
-* Create a draft of the [release](https://github.com/rancher/terraform-provider-rancher2/releases) and select create new tag for the version you are releasing
-* Create release notes by clicking `Generate release notes`
-* Copy the release notes to the CHANGELOG and update to the following format
-
-```
-# <tag version> (Month Day, Year)
-FEATURES:
-ENHANCEMENTS:
-BUG FIXES:
-```
+* Make sure that the various QA teams have approved the rc versions, see [test process](./docs/test-process.md) for more information.
+* Update the `CHANGELOG.md` with the release notes
+* Push a tag to the release branch (`release/v2`, `release/v3`, or `master`) which does not have a `-rc` suffix
+* The CI will build the provider and generate a release on GitHub
+* Make sure to validate that the release is picked up by the Terraform registry, you may need to find the "resync" button to accomplish this.
 
-* Create a PR to update CHANGELOG
-* Copy the updated notes back to the draft release and save (DO NOT release with just the generated notes. Those are just a template to help you)
-* Undraft the release, which creates the tag and builds the release
-* If necessary - create a followup PR to edit [`./docs/compatibility-matrix.md`](https://github.com/rancher/terraform-provider-rancher2/blob/master/docs/compatibility-matrix.md) with the new version information
