 # Container
 
+__Docker__ and __Podman__ are different implementations of an OCI container runtime. There are distinct differences (see below) although their usage is more or less the same. The usage is mutual exclusive, i.e. __you cannot use/install both at the same time!__
+
+One very confusing fact is, that if you installed _Podman_ you still have a command called `docker` available. Therefore you might experience differences in behaviour by executing the very exact commmand on different systems (which either have Podman or Docker installed).
+
+
 !!! warning
     Although we enable you to use both container runtimes Podman and Docker it is important to note that only Podman is supported by RedHat. So if you have a critical application and need/want to also rely on Redhat third level support you'd have to use Podman!
