What is it?
yadm is a software, which essentially bundles git to be used for dotfiles management. This is its website.
How I use it?
I use it instead of git to upload my dotfiles to my Forgejo instance. It doesn’t need to have .git folder in $HOME directory and it nicely packages git for this purpose.
Once I make changes, I can just run yadm add <file>, yadm commit -m <message> and yadm push.
On other machines, one can just do yadm clone or yadm pull and you are good to go.
