Hi, first of all thanks for this super-handy script!! I successfully installed docker on my DS418 NAS using this gist

If you are interested I have made some improvements in my fork: https://gist.github.com/DaveMDS/c35d77e51e0186a4fe2e577f51a5b09a

The main change I have made is to install compose in a more simple and modern way (installed as a CLI plugin), also made a small change to the group creation command to not fail if the group already exists. And updated docker version to latest available.

You can see the diff at: https://gist.github.com/DaveMDS/c35d77e51e0186a4fe2e577f51a5b09a/revisions

Thanks again for your work!

This way compose doesnt get installed here. ds218. How can i turn this to the old way? So i can install the latest compose?
