-### Testing using Docker environment 
+### Testing using a Container environment
+
+Note: The example commands below use `podman`, but you can replace it with a
+compatible tool, such as `docker`.
 
 A containerized development environment can be built using the local
-Dockerfile. You can build it with the following command:
+Containerfile. You can build it with the following command:
 
 ```bash
-docker build -t webdev .
+podman build -t webdev -f Containerfile .
 ```
 
 This action will produce a `webdev` image, with all the website's build
-prerequisites preinstalled. When a container is run from this image, it
-will perform a `jekyll serve` command with the polling option enabled,
-so that changes you make locally will be immediately reflected after
-reloading the page in your browser.
-
-When you run a container using the webdev image, your current working
-directory will be mounted, so that any changes made by the build inside
-the container will be reflected in your local workspace. This is done with
-the `-v` flag. To run the container, execute the following command:
+prerequisites preinstalled. When a container is run from this image, it will
+perform a `jekyll serve` command with the polling option enabled, so that
+changes you make locally will be immediately reflected after reloading the page
+in your browser. To run the container, execute the following command:
 
 ```bash
-docker run -d -v "$PWD":/mnt/workdir -p 4000:4000 webdev
+podman run -i -t --rm -v "$(pwd)":/mnt/workdir:Z -p 4000:4000 webdev
 ```
 
+Flags used in this command are as follows:
+
+* `-i` : run interactively, to send keyboard commands to the process
+* `-t` : allocate a psuedo-TTY, to send signals like with Ctrl-C to exit
+* `--rm` : clean up the container resources after exiting
+* `-v "$(pwd)":/mnt/workdir:Z` : mount your current working directory, so that
+  any changes made by the build inside the container will be reflected in the
+  local workspace on the host; `:Z` causes the host files to be labeled for
+  SELinux, so the container can access them; the most recent container running
+  will relabel for its own access; use lower-case `:z` instead, if you need the
+  directory to be shared across multiple running containers at the same time;
+  restore any labels to their system defaults with `restorecon -RFv .`.
+* `-p 4000:4000` : forward port TCP from the container to the host, so you can
+  view the served Jekyll site in a browser on the host
+
 While this container is running, you will be able to review the rendered website
 in your local browser at [http://127.0.0.1:4000/](http://127.0.0.1:4000/).
 
 Shell access can be obtained by overriding the default container command.
