+# LS Test Harness
+
+Minimal, single-header unit test framework for C.
+
+- Auto-registers test functions.
+- Header-only.
+- Macros: `ASSERT_EQ`, `ASSERT`, etc.
+- ANSI C with minimal extensions.
+
+## Quick Start
+
+1. Copy `ls_test.h` to your project.
+2. In one C file:
+    ```c
+    #define LS_TEST_IMPLEMENTATION
+    #include "ls_test.h"
+    ```
+3. Write tests:
+    ```c
+    TEST_CASE(my_test) {
+        ASSERT_EQ(add(1,2), 3, "%d");
+        return 0;
+    }
+    ```
+4. Add main:
+    ```c
+    TEST_MAIN
+    ```
+5. Compile and run.
