+## Flake-based development shell for Nix
+
+
+### Instructions
+
+- Make sure you have installed Nix and have [enabled Nix flakes](https://nixos.wiki/wiki/Flakes) in your local environment.
+
+- Fork project as template.
+
+- Then `git clone` on your project fork
+
+- After putting your dependencies in `shell.nix`, run `flake develop` to initialize project (if you have `direnv`, then run `direnv allow` and thereafter the project will be initialized automatically when you `cd` into that directory)
+
+### Nix package source
+
+I have this flake pinned to my fork of `nixpkgs`, but you are free to change the `nixpkgs` to the original `NixOS` `nixpkgs`, or any other fork or commit that you wish. The settingi to change is `inputs.nixpkgs.url` (same applies to my fork of `flake-utils`, which is this project's only dependency outside of Nix itself).
+
+### Dependencies
+
+The template only has `jq` as a project dependency, but you are free to use any project dependency that is available in recent `nixpkgs`.
+
+### License
+
+Dual-licensed under MIT or the UNLICENSE.
