+## Usage
+
+The repository does not contain task inputs as my own inputs are located
+in a private repository. If you wish to use this repository with your
+own inputs provide them in the following folder structure:
+
+```sh
+resources
+├── 2015
+│   ├── 01
+│   │   └── input.txt
+│   ├── 02
+│   │   └── input.txt
+│   │  ...
+│   └── 25
+│       └── input.txt
+│   ...
+└── 2023
+    ├── 01
+    │   ├── example.1.txt
+    │   ├── example.2.txt
+    │   └── input.txt
+    │  ...
+    └── 25
+        └── input.txt 
+```
+
+### Cloning
+
+> Reference for myself, cloning with my private inputs
