 # Configuring Docker on various distributions
 
-After successfully installing the Docker daemon on a distribution, it runs with it's default

-Docker can be configured by passing the config flags to the daemon directly if the daemon

+## Direct Configuration

+If you're running the `docker` daemon directly by running `docker -d` instead of using a process manager,
+you can append the config options to the run command directly.
+
+
+Here is a an example of running the `docker` daemon with config options:
+
+    docker -d -D --tls=false -H tcp://0.0.0.0:2375

+These options :

+- Enable `-D` (debug) mode 
+- Set `tls` to false
+- Listen for connections on `tcp://0.0.0.0:2375`

 ### Configuring Docker
 
-Docker options can be configured by editing the file `/etc/default/docker`. If this file does not 
-exist, it needs to be createdThis file contains a variable named `DOCKER_OPTS`. All the 
-config options need to be placed in this variable. For example
+You configure the `docker` daemon in the `/etc/default/docker` file on your
+system.  You do this by specifying values in a `DOCKER_OPTS` variable. 
+To configure Docker options:
+
+1. Log into your system as a user with `sudo` or `root` privileges.
+
+2. If you don't have one, create the `/etc/default/docker` file in your system. 
+
+	Depending on how you installed Docker, you may already have this file.
+
+3. Open the file with your favorite editor.
 
-    DOCKER_OPTS=" --dns 8.8.8.8 -D --tls=false -H tcp://0.0.0.0:2375 "
+		$ sudo vi /etc/default/docker

+4. Add a `DOCKER_OPTS` variable with the following options. These options are appended to the
+`docker` daemon's run command.
 
-The above daemon options : 
+	``` 
+	 DOCKER_OPTS=" --dns 8.8.8.8 --dns 8.8.4.4 -D --tls=false -H tcp://0.0.0.0:2375 "
+	```

+These options : 
 
-1. Set dns server for all containers
+- Set `dns` server for all containers
+- Enable `-D` (debug) mode 
+- Set `tls` to false
+- Listen for connections on `tcp://0.0.0.0:2375`
+  
+5. Save and close the file.
 
-2. Enable Debug mode 
+6. Restart the `docker` daemon.
 
-3. Set tls to false
+ 		 $ sudo restart docker
 
-4. Make the daemon listen for connections on `tcp://0.0.0.0:2375`
+7. Verify that the `docker` daemon is running as specified wit the `ps` command.
 
-After saving the file, restart docker using `sudo restart docker`. Verify that the daemon is
-running with the options specified by running `ps aux | grep docker | grep -v grep`
