+# Aux Foundation
+
+Aux Foundation provides a set of foundational packages which are required for bootstrapping
+a larger package set.
+
+## Usage
+
+Packages can be imported both with and without Nix Flakes. To import them using Nix Flakes,
+add this repository as an input.
+
+```nix
+inputs.foundation.url = "https://git.auxolotl.org/auxolotl/labs/archive/main.tar.gz?dir=foundation";
+```
+
+To import this library without using Nix Flakes, you will need to use `fetchTarball` and
+import the library entrypoint.
+
+```nix
+let
+    labs = builtins.fetchTarball {
+        url = "https://git.auxolotl.org/auxolotl/labs/archive/main.tar.gz";
+        sha256 = "<sha256>";
+    };
+    foundation = import "${labs}/foundation" {
+        # Specifying a system is optional. By default it will use the current system.
+        system = "i686-linux";
+    };
+in
+    # ...
+```
+
+## Development
+
+This foundational package set is created using modules. Each builder and package is separated
+accordingly and can be found in their respective directories. In addition, packages are grouped
+into the different stages of the bootstrapping process.
+
+### Inputs
+
+Due to the fundamental nature of this project, the only accepted input is `lib` which itself
+has no dependencies. _Everything_ else must be built from scratch in the package set.
+
+### Formatting
+
+> **Note**
+> To keep this flake light and keep its inputs empty we do not include a package
+> set which would provide a formatter. Instead please run `nix run nixpkgs#nixfmt-rfc-style`
+> until an improved solution is available.
+
+All code in this project must be formatted using the provided formatter in the `flake.nix`
+file. You can run this formatter using the command `nix fmt` (not currently available).
+
+### Code Quality
+
+In order to keep the project approachable and easy to maintain, certain patterns are not allowed.
+In particular, the use of `with` and `rec` are not allowed. Additionally, you should prefer the
+fully qualified name of a variable rather than creating intermediate ones using `inherit`.
+
+### Builders
+
+Builders are wrappers around `builtins.derivation` and provide additional functionality via
+abstraction. They can be found in [`./src/builders`](./src/builders). Each builder specifies
+its own `build` function which can be called elsewhere in the package set to construct packages.
+
+For example, here is a module that makes use of the `kaem` builder:
+
+```nix
+{config}: let
+    builders = config.aux.foundation.builders;
+    stage0 = config.aux.foundation.stages.stage0;
+
+    package = builders.kaem.build {
+        name = "my-package";
+
+        deps.build.host = [
+            stage0.mescc-tools.package
+            stage0.mescc-tools-extra.package
+        ];
+
+        script = ''
+            mkdir ''${out}/bin
+            cp ${./my-binary} ''${out}/bin/my-package
+            chmod 555 ''${out}/bin/my-package
+        '';
+    };
+in
+    # ...
+```
+
+### Stages
+
+The bootstrapping process is broken up into different stages which focus on different goals.
+Each stage can be found in [`./src/stages`](./src/stages).
+
+#### Stage 0
+
+This stage is responsible for starting with a single binary seed and producing the tools
+necessary to compile (simple) C code. This stage will then compile the original tools it
+used from C sources.
+
+#### Stage 1
+
+This stage is responsible for building up to a recent version of `gcc`. Along with the
+compiler, this stage provides things like `bash`, `coreutils`, `gnumake`, and several
+other important tools.
+
+#### Stage 2
+
+This stage refines the existing packages by building static binaries as well as the most recent
+versions of the tools. In addition, certain load-bearing packages such as `patchelf` and `glibc`
+are built.

+Subject: [PATCH 1/2] No impure bin sh
+
+default_shell is used to populuate default shell used to execute jobs.
+Unless SHELL is set to a different value this would be /bin/sh.
+Our stdenv provides sh in form of bash anyway. Having this value not
+hard-coded has some advantages:
+
+- It would ensure that on all systems it uses sh from its PATH rather
+  than /bin/sh, which helps as different systems might have different
+  shells there (bash vs. dash)
+- In the past I had issues with LD_PRELOAD with BEAR, where /bin/sh
+  used a different glibc than BEAR which came from my development shell.
