 The simplest and fastest way to get S6 supervisor in your image
 
+This docker image packages s6 supervisor overlay based on https://github.com/just-containers/s6-overlay releases.
+
+
+NOTE: GitHub Actions builds are currently broken. Images are, however manually built, so you should be still getting latest version.
+
 ### Usage
 ```Docker
-COPY --from=nlss/s6-rootfs:latest ["/", "/"]
+COPY --from=ghcr.io/n0rthernl1ghts/s6-rootfs:latest ["/", "/"]
 ```
 or with fixed version:
 ```Docker
-COPY --from=nlss/s6-rootfs:3.1.2.1 ["/", "/"]
+COPY --from=ghcr.io/n0rthernl1ghts/s6-rootfs:3.2.0.2 ["/", "/"]
 ```
 
 That's it!
 
+Note: We have moved to `ghcr.io`. Docker hub `docker.io/nlss/s6-rootfs` builds are discontinued.<br/>
