+2. This file is sensible to white spaces. Therefore, make sure there isn't an additional white space at the end of the key, otherwise it won't work.

-In order to display plots in the docker container, we need to configure our XServer.  Users familiar with Docker can just set the DISPLAY variable in their file described above.
+Users familiar with Docker and X-Server can set the `DISPLAY` variable in the file [setenv](/docker/setenv) described above. If you use this approach remember to add `:0` at the end of your inet address. E.g. `DISPLAY=192.168.1.155:0`.
+
+### X-Server
 
 For help setting up the X-Server, I will go through this now:
 
-### Setting up X Quartz/X11
+#### Setting up X Quartz/X11
 
 0. Install X Quartz from  https://www.xquartz.org/
 1. With X Quartz open: go to Preferences -> Security and make sure both options are enabled.

-### Adding the display for Docker
+#### Adding the display for Docker
 
 From the command prompt or terminal, run the following to add your local configuration to the list of allowed access control:
 ```bash
-IP=$(ifconfig en1 | grep inet | awk '$1=="inet" {print $2}')
+IP=$(ifconfig | grep inet | grep -v -e "127.0.0.1" | awk '$1=="inet" {print $2}')
 xhost + $IP
 ```
 
 Now we can run the docker container, adding the display to the environment:
 ```bach
-docker run -it --rm --env-file=path/to/file -e DISPLAY=$IP:0 ghcr.io/gamestonkterminal/gst-poetry:latest
+docker run -it --rm --env-file=path/to/setenv -e DISPLAY=$IP:0 ghcr.io/gamestonkterminal/gst-poetry:latest
 ```
+
 This container will be able to display all the same plots as the terminal interface.
