+alpine-x86_64-glibc
+===================
+
+This repository contains a dockerfile to add a `pre-built glibc`_ to an
+otherwise emtpy alpine container. This is necessary for some software
+that is shipped precompiled and linked against glibc only. `Alpine Linux`_
+itself uses the much smaller and faster `musl libc`_ (which is also considered
+often as a more secure replacement for the glibc).
+
+Usage
+-----
+
+To use this image you need the base alpine image (either from a registry, then
+you need to edit the Dockerfile, or -- preferred -- self-build as alpine-x86_64)
+and podman or docker installed. Then simply build the image based on the
+dockerfile:
+
+.. code:: shell
+
+   podman build . -t alpine-glibc-x86_64:3.11.6_2.31-r0
+
+The tag is a suggestion to include both the alpine and the glibc version.
