You can run ledder with docker or directly with NodeJS.
Go the the cloned reposity.
If you run it the first time, or did an update:
npm install
npm run build
Installing/building takes long, but after that starting will be fast:
npm start
It will automatically create a new displayconf.js
Go to http://localhost:3000

If you cloned the repository, create a displayconf.js file and do:
docker-compose up --build
Takes a while, since it has to render the previews the first time.
It will use the presets directory from the repository, so presets you safe will be permanent.
Go to http://localhost:3000
We also have official docker images. (we also use them on the Raspberry Pi)
Create a displayconf.js and run:
docker run --name ledder -p 3000:3000 -v ./displayconf.js:/app/displayconf.js psy0rz/ledder
To update etc just do the regular docker things or create a docker-compose.js to make life easier :)
