+# Advent of Code 2025 - Rust
+
+## Daily Workflow
+
+To add a new day's solution (e.g., Day 2):
+
+1.  **Create the Source File**:
+    - Copy `src/days/day01.rs` to `src/days/day02.rs`.
+    - Update the logic in `part1` and `part2`.
+
+2.  **Register the Module**:
+    - Open `src/days/mod.rs`.
+    - Add `pub mod day02;` at the top.
+    - Add a match arm for the new day:
+      ```rust
+      2 => day02::run(),
+      ```
+
+3.  **Add Input**:
+    - Create a new file `inputs/day02.txt`.
+    - Paste your puzzle input into it.
+
+4.  **Run**:
+    - Execute the solution with:
+      ```bash
+      cargo run 2
+      ```
