+# Toki's Nix Flake Template Repository
+
+This is my personal collection of Nix flake templates for various programming
+languages and build systems.
+
+## Motivation
+
+There already exists a [semi-official repository of flake
+templates](https://github.com/NixOS/templates), so why make my own?
+
+I have a few different reasons:
+
+- **Comprehensiveness:** The official template repository is rather small and
+  doesn't have most of the templates I would actually want to use.
+- **Consistency:** The templates in the official repository are contributed by
+  community members, and there's very little stylistic or structural consistency
+  between them.
+- **Preference:** The structure of a flake can be very opinionated, and most of
+  the official flake templates are rather poorly constructed by my standards,
+  often not bothering to follow established best practices.
+
+## Usage
+
+Flake templates are used with the `nix flake init` command:
+
+```sh
+nix flake init -t git+https://git.tokinanpa.dev/toki/templates#<template>
+```
+
+Replace `<template>` with the template you want to use. In the simplest case,
+this is just the name of the programming language you want to use; the
+repository will pick a recommended default template for that language.
+
+If you want more control over the generated repository, you may select a
+specific template instead. Templates names are organized by underscore-separated
+*fields*; the number of fields may very depending on the language, but typically
+there are three or four:
+
+1. The programming language
+2. The build system used to compile/package the repository
+3. The Nix library/evaluation system used in the flake itself
+4. (Optional) Additional differences in project structure
+
+For example, the `python_pyproject_nixpkgs_cli` template generates a Python
+repository packaged in Pyproject format where the flake uses Nixpkgs' standard
+derivation builders (`buildPythonPackage`) and the repository exposes a CLI application.
