+# Basic Example
+
+This directory contains a simple example demonstrating the usage of the IOC library.
+
+## Files
+
+- `main.cpp` - Basic example code showing how to use the IOC dependency injection system
+- `CMakeLists.txt` - Build configuration (placeholder, the example is built from the root CMakeLists.txt)
+
+## Running the Example
+
+To build and run this example:
+
+1. From the repository root, build with examples enabled:
+   ```bash
+   mkdir build && cd build
+   cmake .. -DIOC_BUILD_EXAMPLES=ON
+   make
+   ```
+
+2. Run the example:
+   ```bash
+   ./IOC_example
+   ```
+
+The example demonstrates the dependency injection container managing employee and department services with logging and database access.
