+# dcr fmt
+
+Formats all C/C++ source files using `clang-format`.
+
+## Usage
+
+```sh
+dcr fmt
+```
+
+## Behavior
+
+1. Scans `src/` and `tests/` directories recursively.
+2. Formats all C/C++ source and header files (`.c`, `.cpp`, `.cxx`, `.cc`, `.h`, `.hpp`, `.hxx`, `.hh`) using `clang-format`.
+3. Uses `.clang-format` if present in the project root, otherwise falls back to LLVM style.
+
+## Requirements
+
+- `clang-format` must be installed and available in PATH.
