 # Static browser server
 
 A simple service worker used for the static template in sandpack, allowing users to develop websites like they would locally in the browser.
+
+# Docker Build
+
+Build docker image using the follow build command
+
+```
+docker buildx build --platform linux/amd64 -t static-browser-server:0.1.0 .
+```
+
+Run the docker image as follows
+```
+docker run --rm -p 8080:80 athenaintel/sandpack-static-server:0.1.0
+```
+
+Test by visiting the following address, you should see some HTML.
+```
+curl http://localhost:8080
+```
+
+In production you need to put this service behind a wildcard DNS record so dynamic URLs can be generated, that is beyond the scope of this doc.
