-## Setup: </br>
-Although not required, it is recommended to give Zoraxy a dedicated location on the host to mount the container. That way, the host/user can access them whenever needed. A volume will be created automatically within Docker if a location is not specified. </br>
+## Usage
 
-You may also need to portforward your 80/443 to allow http and https traffic. If you are accessing the interface from outside of the local network, you may also need to forward your management port. If you know how to do this, great! If not, find the manufacturer of your router and search on how to do that. There are too many to be listed here. </br>
+If you are attempting to access your service from outside your network, make sure to forward ports 80 and 443 to the Zoraxy host to allow web traffic. If you know how to do this, great! If not, find the manufacturer of your router and search on how to do that. There are too many to be listed here. Read more about it from [whatismyip](https://www.whatismyip.com/port-forwarding/).
 
-The examples below are not exactly how it should be set up, rather they give a general idea of usage.
+In the examples below, make sure to update `/path/to/zoraxy/config/`. If a path is not provided, a Docker volume will be created at the location but it is recommended to store the data at a defined host location or a named Docker volume.
+
+Once setup, access the webui at `http://<host-ip>:8000` to configure Zoraxy. Change the port in the URL if you changed the management port.

-
-| Operator | Need | Details |
-|:-|:-|:-|
-| `-d` | Yes | will run the container in the background. |
-| `--name (container name)` | No | Sets the name of the container to the following word. You can change this to whatever you want. |
-| `-p (ports)` | Yes | Depending on how your network is setup, you may need to portforward 80, 443, and the management port. |
-| `-v (path to storage directory):/opt/zoraxy/config/` | Recommend | Sets the folder that holds your files. This should be the place you just chose. By default, it will create a Docker volume for the files for persistency but they will not be accessible. |
-| `-v /var/run/docker.sock:/var/run/docker.sock` | No | Used for autodiscovery. |
-| `-e (flag)="(value)"` | No | Arguments to run Zoraxy with. They are simply just capitalized Zoraxy flags. `-docker=true` is always set by default. See examples below. |
-| `zoraxydocker/zoraxy:latest` | Yes | The repository on Docker hub. By default, it is the latest version that is published. |

+
+### Building
+
+To build the Docker image:
+  - Check out the repository/branch.
+  - Copy the Zoraxy `src/` directory into the `docker/` (here) directory.
+  - Run the build command with `docker build -t zoraxy_build .`
+  - You can now use the image `zoraxy_build`
+    - If you wish to change the image name, then modify`zoraxy_build` in the previous step and then build again.
