+# Prusaslicer noVNC Docker Container
+
+## Overview
+
+This is a super basic noVNC build using supervisor to serve Prusaslicer in your favorite web browser. This was primarily built for users using the [popular unraid NAS software](https://unraid.net), to allow them to quickly hop in a browser, slice, and upload their favorite 3D prints.
+
+A lot of this was branched off of dmagyar's awesome [prusaslicer-vnc-docker](https://hub.docker.com/r/dmagyar/prusaslicer-vnc-docker/) project, but I found it to be a bit complex for my needs and thought this approach would simplify things a lot.
+
+## How to use
+
+**In unraid**
+
+If you're using unraid, open your Docker page and under `Template repositories`, add `https://github.com/helfrichmichael/unraid-templates` and save it. You should then be able to Add Container for prusaslicer-novnc. For unraid, the template will default to 6080 for the noVNC web instance.
+
+**Outside of unraid**
+
+To run this image, you can run the following command: `docker run --detach --volume=prusaslicer-novnc-data:/configs/ -p 8080:8080 -e SSL_CERT_FILE="/etc/ssl/certs/ca-certificates.crt" 
+--name=prusaslicer-novnc prusaslicer-novnc`
+
+This will bind `/configs/` in the container to a local volume on my machine named `prusaslicer-novnc-data`, it will bind port `8080` to `8080`, and finally, it will provide an environment variable to keep Prusaslicer happy by providing an `SSL_CERT_FILE`.
