In a container

The editor can also run from a container, for a server on your own network or to run it locally:

docker run --rm -p 8080:80 ghcr.io/scm-js/scm-js:latest

then open http://localhost:8080. The image is the same editor as the numbered release it is tagged with, and carries no game data, so it asks for the graphics like the hosted editor. To serve graphics you have already extracted instead, see game-data.md.

Each release also has scmJS-web.zip, the same editor as plain files. Unpack it at the root of any static web server.
