Set up on the computer with `wget https://git.navidsassan.ch/navid.sassan/computercraft/raw/branch/master/get get`. Make sure to enable the http API in the computercraft config file on the server. Then use `get README.md` for example, to download the `README.md`. You can store scripts in `resourcepacks/assets/computercraft/lua/rom/programs/` on the server for them to be available on all turtles.
