+### steamcmd-docker
+Extended version of [CM2Walki/steamcmd] (https://www.github.com/CM2Walki/steamcmd)  
+
+Based on Fedora 35, a newer/more familiar OS (for me).  Runs `steamcmd` once on build to update the client from the archive.  No other notable changes.
+
+Some bootstrap utilities left around for convenience (eg: `wget`, `less`, `find`), at the cost of size.  That is *not* a priority for this image, nearing 500MB.
