+# Workspace Instructions
+
+- Keep the project compatible with C11 and CMake 3.16 or newer.
+- Put public headers in `include/`, implementations in `src/`, and tests in `tests/`.
+- Keep reusable functionality in libraries and link executables to those libraries.
+- Register tests with CTest and avoid adding dependencies unless the project needs them.
+- Verify changes with `cmake -S . -B build`, `cmake --build build`, and `ctest --test-dir build --output-on-failure`.

+## Requirements
+
+- CMake 3.16 or newer
+- A C compiler with C11 support
+
+## Configure and build
+
+```sh
+cmake -S . -B build
+cmake --build build
+```
+
+## Run
+
+```sh
+./build/c_template
+```
+
+## Test
+
+```sh
+ctest --test-dir build --output-on-failure
+```
+
+The `greeting` library is an example of how to separate reusable code into a
+public header and implementation. Replace it with your project's own modules.
