+### Helm Verison Bumps
+
+**Chart Version :** When bumping the chart version follow semantic versioning https://semver.org/<br />
+**App Version :** When bumping the app version you will also need to bump the chart verison too. Again, follow semantic verisoning when bumping the chart.
+
+To determine if you need tp bump the MAJOR, MINOR or PATCH versions you will need to review the changes between the previous app version and the new app verison and / or ask for a maintainer to advise.

-# Alternatives
 
-The following is a list of alternative solutions that may better fit you depending on your use-case:
-
-- <https://github.com/evryfs/github-actions-runner-operator/>
-- <https://github.com/philips-labs/terraform-aws-github-runner/>
-
-Although the situation can change over time, as of writing this sentence, the benefits of using `actions-runner-controller` over the alternatives are:
-
-- `actions-runner-controller` has the ability to autoscale runners based on number of pending/progressing jobs (#99)
-- `actions-runner-controller` is able to gracefully stop runners (#103)
-- `actions-runner-controller` has ARM support
-- `actions-runner-controller` has GitHub Enterprise support (see [GitHub Enterprise support](#github-enterprise-support) section for caveats)
