 # sculpin-talk-demo
 
+A demonstration [Sculpin](https://sculpin.io) website, generated from my [Sculpin Skeleton](https://github.com/opdavies/sculpin-skeleton) project.
+
+## Running locally
+
+The easiest way to run the site locally is by using my [Sculpin Serve docker image](https://github.com/opdavies/docker-image-sculpin-serve):
+
     docker run --rm -it \
         -p 8000:8000 \
         -v $(pwd):/app \
         --name sculpin-demo \
         opdavies/sculpin-serve
+
+This will install the Composer dependencies, generate and serve the site at http://localhost:8000, and automatically re-generate the site if any changes are made.
