 * If you specify `BASH_ENV`, then all your `#!/bin/bash` scripts
 do not need to call `scl enable`.
 * If you specify `PROMPT_COMMAND`, then on execution of the
-`docker exec ... /bin/bash` command, the collection will be automatically enabled.
+`podman exec ... /bin/bash` command, the collection will be automatically enabled.
 
 *Note*:
 Executables in Software Collections packages (e.g., `ruby`)
 are not directly in a directory named in the `PATH` environment variable.
 This means that you cannot do:
 
-    $ docker exec <cid> ... ruby
+    $ podman exec <cid> ... ruby
 
 but must instead do:
 
-    $ docker exec <cid> ... /bin/bash -c ruby
+    $ podman exec <cid> ... /bin/bash -c ruby
 
 The `/bin/bash -c`, along with the setting the appropriate environment variable,
 ensures the correct `ruby` executable is found and invoked.
 
+Note: while the examples in this README are calling `podman`, you can replace any such calls by `docker` with the same arguments
