To initialize (where ${ENV} is listed in the table below):

nix flake init --template github:the-nix-way/dev-templates#${ENV}

Here's an example (for the rust template):

# Initialize in the current project
nix flake init --template github:the-nix-way/dev-templates#rust

# Create a new project
nix flake new --template github:the-nix-way/dev-templates#rust ${NEW_PROJECT_DIRECTORY}

Once your preferred template has been initialized, you can use the provided shell in two ways:

1. If you have nix-direnv installed, you can initialize the environment by running direnv allow.
2. If you don't have nix-direnv installed, you can run nix develop to open up the Nix-defined shell.

The sections below list what each template includes. In all cases, you're free to add and remove packages as you see fit; the templates are just boilerplate.
