 #### Multi Architecture
-Images are built primarily for `amd64` architecture, and may also include builds for `arm/v6`, `arm/v7`, `arm64` and others. These variants are all unsupported. Consider [sponsoring](https://github.com/sponsors/tiredofit) my work so that I can work with various hardware. To see if this image supports multiple architecures, type `docker manifest (image):(tag)`
