The prerequisite is that docker is installed and running correctly.
Create a folder, open a prompt in it, run the command:
docker run -v ./:/output ghcr.io/d-fens/tstomirror:main
Download the docker-compose.yml file into an empty directory.
Run docker compose run mirror in a command prompt in the same folder.
Check the folder contains the folder oct2018-4-35-0-uam5h44a.tstodlc.eamobile.com and a log file of the run called debug.log. If run from the same folder it will refresh the content.
A number of older files will be missing from the output and have a WARNING message in the logs.
