 # Let's Fight With CMake, Docker, and Some Dependencies
+# CMake Exercise: Dependency Management with Docker
 
-Repository for the [CMake exercise](https://github.com/Simulation-Software-Engineering/Lecture-Material/blob/main/03_building_and_packaging/cmake_exercise.md).
+This repository contains the solution for the CMake exercise. It demonstrates how to manage complex C++ dependencies (Deal.II, MPI, PETSc, Trilinos, TBB, Boost, and yaml-cpp) using a reproducible Docker environment.
+
+## Overview
+
+The project compiles a C++ application that performs:
+1.  **FEM Simulation:** Solves a Poisson problem using Deal.II.
+2.  **Flatset Manipulation:** Uses Boost Container.
+3.  **Filesystem Inspection:** Uses Boost Filesystem.
+4.  **YAML Parsing:** Uses a manually built version of `yaml-cpp`.
+
+## Prerequisites
+
+- Docker
+
+## How to Build and Run
+
+1.  **Build the Docker Image:**
+    ```bash
+    docker build -t cmake-exercise .
+    ```
+
+2.  **Run the Container:**
+    ```bash
+    # Linux/Mac
+    docker run -it -v $(pwd):/cmake-exercise cmake-exercise bash
+
+    # Windows PowerShell
+    docker run -it -v ${PWD}:/cmake-exercise cmake-exercise bash
+    ```
+
+3.  **Compile and Run (inside the container):**
+    The repository includes a helper script to build and execute the program:
+    ```bash
+    ./build_and_run.sh
+    ```
+
+4.  **Test YAML Parser:**
+    To manually test the YAML parser functionality:
+    ```bash
+    ./build/main yamlParser/config.yml
+    ```
+
+## Dependencies
+
+The `Dockerfile` handles the installation of:
+- `build-essential`, `cmake`, `git`, `wget`, `unzip`, `vim`
+- `libboost-all-dev`
+- `libdeal.ii-dev`
+- `mpi-default-dev`
+- `libkokkos-dev`
+- `libtrilinos-*` packages
+- `libpetsc-real-dev`
+- `libtbb-dev`
+- `yaml-cpp` (v0.6.3 built from source)
