 In the same way that [brew](https://brew.sh) uses git and Makefiles to compile applications for your Mac, `arkade` uses upstream [helm](https://helm.sh) charts and `kubectl` to install applications to your Kubernetes cluster. arkade exposes strongly-typed flags for the various popular options for helm charts, and enables easier discovery through `arkade install --help` and `arkade install APP --help`.
 
+### Is arkade suitable for production use?
+
+If you consider helm suitable, and `kubectl` then yes, arkade by definition uses those tools and the upstream artifacts of OSS projects.

 ### What is in scope for `arkade get`?
 
 Generally speaking, tools that are used with the various arkade apps or with Kubernetes are in scope. If you want to propose a tool, raise a GitHub issue.
