Enabling direnv would greatly enhance the development experience. Once enabled, all dependencies will be installed, and the shell will be augmented according to the specifications in flake.nix whenever you enter the project directory from your shell. The initial setup might take a bit longer when entering the project directory for the first time.
direnv can be enabled or disabled using direnv allow and direnv deny respectively. If you're new to direnv, it is also recommended to integrate it with your shell first.
