+### Distroless Docker Images
+
+> [!CAUTION]
+> This image comes without a shell, and external filtering and actions relying on `exec` will therefore not work with anything but compiled static binaries.
+> 
+> To clarify: **`BASH` and `SH` shell scripts WILL NOT WORK!**
+>
+> Use the standard image if you rely on this functionality.
+
+For users who prioritize container security, one of the longterm maintainers offer alternative Docker images built on [Distroless](https://github.com/GoogleContainerTools/distroless). Specifically the `distroless/static-debian12:nonroot` base image.
+
+Distroless images do not contain a package manager or shell, thereby reducing the potential attack surface and making them a more secure option. These stripped-back images contain only the application and its runtime dependencies.
+
+The repository for these builds can be found here: [https://github.com/s0up4200/autobrr-distroless](https://github.com/s0up4200/autobrr-distroless)
