+# static
+
+The [static image](https://gitea.elara.ws/Elara6331/-/packages/container/static/latest) is a basic image with just enough iles to run static binaries. It's meant to be used as a base image and is useless outside of that.
+
+This image will only run static binaries (i.e. Go binaries with `CGO_ENABLED=0`) as it doesn't include musl or glibc
