+# Frozendev Challenges
+
+A repository for storing my subpar solutions to daily challenges, if or when I
+have the time to tackle them. Expect nothing but bad code, I focus on "works"
+before "works well".
+
+## Structure
+
+This repository utilizes Cargo's workspaces feature.
+
+```bash
+├── challenges
+│   └── december-2024
+│       ├── c1
+│       ├── c2
+│       └── c3
+├── lib
+│   └── geometry
+└── shell.nix
+```
+
+- **challenges** is where challenges will go, sorted by month and then by order.
+  Since challenges are not published on a specific schedule, number is
+  incremented whenever there is a new challenge.
+
+- **lib** is where shared code, sorted by functionality, may go. If only one
+  challenge relies on a piece of code, then it may be put inside a `lib` target
+  or simply in `main.rs`.
+
+- **shell.nix** is for the Nix users. It uses an _unlocked_ `<nixpkgs>`
+  instance, since I already lock special lookup paths in my system registry.
