 ## Releasing
 
-To cut a release, push a new tag (versioning discussed below).
-
-### Tagging a release
-
-1. Run `make changes` to review the changes since the last
-   release. Based on the changes, decide what kind of release you are
-   doing (bugfix, feature or breaking).
+1. Use [github-changelog-generator](https://github.com/digitalocean/github-changelog-generator) 
+   to list the changes since the last release 
+   and decide what kind of release you are doing (bugfix, feature or breaking).
    `doctl` follows [semantic versioning](https://semver.org), ask if you aren't sure.
 
-1. Tag the release using `BUMP=(bugfix|feature|breaking) make tag`.
-   (Bugfix, feature and breaking are aliases for semver's patch, minor and major.
-   BUMP will also accept `patch`, `minor` and `major`, if you prefer). The command
-   assumes you have a remote repository named `origin` pointing to this
-   repository. If you'd prefer to specify a different remote repository, you can
-   do so by setting `ORIGIN=(preferred remote name)`.
-
-The new tag triggers the release.
-
-### Snap
-
-Snap packages are automatically built and uploaded as part of the GitHub Actions
-release workflow.
-
-To build a snap package locally for testing, first install `snapcraft`.
-
-On Ubuntu, run:
-
-    sudo snap install snapcraft --classic
-
-Or on MacOS, run:
-
-    brew install snapcraft
-
-Finally, build the package by running:
-
-    make snap
-
-More details about the snap package can be found in the `snap/snapcraft.yaml` file.
-
-### Updating Homebrew
+1. Synchronize your local repository with all the tags that have been created or updated on the remote main branch
+    ```bash
+    git checkout main
+    git pull --tags
+    ```
 
-Using the url and sha from the github release, update the
-[homebrew formula](https://github.com/Homebrew/homebrew-core/blob/master/Formula/doctl.rb).
-You can use `brew bump-formula-pr doctl`, or
+1. Creates a new tag and push the tag to the remote repository named origin
+    ```bash
+    git tag <new-tag> # Example: git tag v1.113.0
+    git push origin tag <new-tag> # Example: git push origin tag v1.113.0
+    ```
 
-1. fork `homebrew-core`
-1. create a branch named `doctl-<version>`
-1. update the url and the sha256 using the values for the archive in the github release
-1. commit your changes
-1. submit a PR to homebrew
