 here's the command:
 
 ```cli
-docker run -d -p 80:80 docker/getting-started
+docker run -d -p 9080:80 docker/getting-started
 ```
 
 You'll notice a few flags being used. Here's some more info on them:
 
 - `-d` - run the container in detached mode (in the background)
-- `-p 80:80` - map port 80 of the host to port 80 in the container
+- `-p 9080:80` - map port 9080 of the host to port 80 in the container
 - `docker/getting-started` - the image to use
 
+!!! info "Deep Dive"
+    One thing you may come across if you already have development environments
+    set-up is that you may be using ports already. Port 80 is frequently blocked
+    by IIs in Windows. By using port 9080 there's a good chance nothing will conflict. 
+    
+    If you have port 9080 used by another process, you can change to another port by 
+    changing the -p argument. E.g. to use port 9999
+    ```
+    docker run -d -p 9999:80 docker/getting-started
+    ```
+

 !!! info "Pro tip"
     You can combine single character flags to shorten the full command.
     As an example, the command above could be written as:
     ```
-    docker run -dp 80:80 docker/getting-started
+    docker run -dp 9080:80 docker/getting-started
     ```
