 2. Check the corresponding code in `src/` to see implementations
 3. Compile and run solutions with a C++ compiler
 
+## Compilation
+
+To build the project, use CMake:
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+```
+
+This will compile both solutions:
+- `ProjectEuler_main` (main.cpp)
+- `ProjectEuler_main-810` (main-810.cpp)
+
+## Solutions
+
+### Problem 810
+- Code: `src/main-810.cpp`
+- Documentation: `solution-docs/problem-810.md`
+
 ## Contributing
 
 Feel free to explore, learn, and suggest improvements. Solutions are written in C++ and aim to balance correctness, efficiency, and clarity.
