 # How to use this image
 
-Since no two users of irssi are likely to configure it exactly alike, this
-image does not come with any default configuration.
-
-Please refer to [upstream's excellent (and comprehensive)
-documentation](http://irssi.org/documentation) on the subject of
-configuring irssi for your needs.
+Because it is unlikely any two irssi users have the same configuration
+preferences, this image does not include an irssi configuration. To configure
+irssi to your liking, please refer to [upstream's excellent (and comprehensive)
++documentation](http://irssi.org/documentation).
 
 Be sure to also checkout the [awesome
 scripts](https://github.com/irssi/scripts.irssi.org) you can download to
 customize your irssi configuration.

 ## Directly via bind mount
 
-    docker run -it --name my-running-irssi -e TERM \
-        -u $(id -u):$(id -g) -v $HOME/.irssi:/home/user/.irssi:ro \
-        -v /etc/localtime:/etc/localtime:ro \
-        irssi
+On a Linux system, build and launch a container named `my-running-irssi` like
+this:
 
-    # in Docker 1.5 you can use the --read-only flag
-    docker run -it --name my-running-irssi -e TERM \
-        -u $(id -u):$(id -g) -v $HOME/.irssi:/home/user/.irssi --read-only \
-        -v /etc/localtime:/etc/localtime \
-        irssi
+    docker run -it --name my-running-irssi -e TERM \ -u $(id -u):$(id -g) -v
+    $HOME/.irssi:/home/user/.irssi:ro \ -v /etc/localtime:/etc/localtime:ro \
+    irssi
 
+On a Mac OS X system, run the same image using:
+
+	docker run -it --name my-running-irssi -e TERM -u $(id -u):$(id -g) \ -v
+	$HOME/.irssi:/home/user/.irssi:ro  irssi
+
+You omit `/etc/localtime` on Mac OS X because `boot2docker` doesn't use this
+file.
+
+Of course, you can name your image anything you like. In Docker 1.5 you can also
+use the `--read-only` mount flag. For example, on Linux:
+
+    docker run -it --name my-running-irssi -e TERM \ -u $(id -u):$(id -g) -v
+    $HOME/.irssi:/home/user/.irssi --read-only \ -v
+    /etc/localtime:/etc/localtime \ irssi
