-The tool has an `release` command which creates new minor version release structure and files.
-The tool has an `update` command which updates upstream supported versions for new patch releases.
+`update` Update new patch version(s) of EKS Go
+
+Work In Progress:
+`patch` Cherrypick a patch to version(s) of EKS Go
 
-The `release` command accepts a EKS Go release version via the flag `eksGoRelease`. 
-For example to release a new version of eksGo `1.21.0`
-you would run the following:
 
 ```shell
-eksGoRelease release --eksGoReleases=1.21.0
+eksGoRelease new --eksGoReleases=1.21.0
 ```
 
 The `update` command accepts a comma-seperated list of EKS Go release versions via the flag `eksGoRelease`. 
 Updates are run for each given release version. For example, to run updaters for the EKS Go release `1.20.2` & `1.19.3`, 
-you would run the following:
-
 ```shell
 eksGoRelease update --eksGoReleases=1.20.2,1.19.3
 ```

+The `release` command accepts a comma-seperated list of EKS Go release versions via the flag `eksGoRelease`. 
+This command is to be run after post-submits and builds pass. This command updates the README and when merged 
+runs the prowjob triggering the sns message.
+```shell
+eksGoRelease release --eksGoReleases=1.20.2,1.19.3
+```
