# mkdir dir
# echo foo > dir/bar

# nix store add ./dir
/nix/store/6pmjx56pm94n66n4qw1nff0y1crm8nqg-dir

Title: nix store add Command

Summary

The `nix store add` command copies a specified path into the Nix store and prints the resulting store path. A critical warning notes that the generated store path is not registered as a garbage collector root, making it susceptible to deletion before manual registration. An example demonstrates adding a directory to the store and verifying its contents through the new store path.
