+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official email address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+contact@mfgames.com. All complaints will be reviewed and investigated promptly
+and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.

+# MfGames Project Setup Flake
+
+_An opinionated setup for projects using Nix flakes._
+
+According to Larry Wall, there are
+[three virtues of a great coder](https://thethreevirtues.com/): laziness,
+impatience, and hubris.
+
+Over the years, the complexity of being a developer has only increased.
+Fortunately (or unfortunately depending the mood), we have embraced laziness and
+developed tools to help automate some of the more tedious tasks to ensure
+everything is formatted correctly and properly recorded. This has resulted in
+libraries such as:
+
+- [EditorConfig](https://editorconfig.org/)
+- [Conform](https://github.com/siderolabs/conform)
+- [Lefthook](https://github.com/evilmartians/lefthook)
+- [Prettier](https://prettier.io/)
+- [Rustfmt](https://rust-lang.github.io/rustfmt/)
+- [Treefmt](https://numtide.github.io/treefmt/)
+
+In addition, we need to document policies that guide our projects:
+
+- [Contributor Convenant](https://www.contributor-covenant.org/)
+- [Developer Certificate of Origin](https://developercertificate.org/)
+
+But, like the rest of the development world, all of these tools change and
+evolve. New tools become useful to ensure formatting while others are taken over
+by successors. Not to mention opinions and aesthetics change and what works
+yesterday doesn't always look right today.
+
+## Nix
+
+This project is intended to be used with [Nix](https://nixos.wiki/wiki/Flakes)
+flakes and can be used directly as an input.
+
+```nix
+{
+  inputs.mfgames-project-setup.url = "git+https://src.mfgames.com/nixos-contrib/mfgames-project-setup-flake.git";
+}
+```
+
+This flake provides a function in `mfgames-project-setup.lib.mkConfig` that
+creates a shell hook and the various tools required to run those hooks (because
+programs like `lefthook` assume that the program is in the `PATH`).
+
+```nix
+config = mfgames-project-setup.lib.mkConfig {
+    inherit system pkgs;
+    # Options go here.
+};
+```
+
+Of course, this being Nix, there are many ways of creating a devShell. This is
+one way of using the config inside the shell.
+
+```nix
+devShells = forEachSupportedSystem ({ system, pkgs }:
+let
+    config = inputs.mfgames-project-setup.lib.mkConfig {
+        inherit system pkgs;
+        conform.scopes = [ "cli" "website" ];
+        rust.enable = false;
+    };
+in
+{
+    default = pkgs.mkShell {
+        # Add in the required packages for the configuration.
+        packages = [] ++ config.packages;
+
+        # Add in the
+        shellHook = ''
+            ${config.shellHook}
+        '';
+    };
+});
+```
+
+## Options
+
+This is definately opinionated, mainly by the virtue that is primarily used by a
+single developer. Internally, this uses
+[Nixago](https://github.com/nix-community/nixago) (including a little hacking
+for text files).
+
+### conform.scopes
+
+Controls which scope is allowed inside the
+[Conventional Commit](https://www.conventionalcommits.org/en/v1.0.0/).
+
+Defaults to `[]`. An example would be `["cli" "infra"]`.
+
+### contributorCovenant.enable
+
+If set to true, then a `CODE_OF_CONDUCT.md` will be created using information
+from `contributorCovenant.contact` for the contact information. If the contact
+is missing, this will assert.
+
+Defaults to `false`.
+
+### contributorCovenant.contact
+
+Set this to the value for the contact information inside the
+`CODE_OF_CONDUCT.md` file. This can be an email or a website.
+
+### developerCertificateOfOrigin.enable
+
+If set to true, then a `DCO.md` will be created using the boilerplate text from
+https://developercertificate.org/.
+
+Defaults to `false`.
+
+### rust.enable
+
+If set to true, then `rustfmt.toml` will be created.
