+# Magic Scrolls
+
+Server-side game engine for the game "Magic Scrolls".
+
+This engine is building as:
+
+- **Core**: provides event bus, database providers factory, module registration, lifecycle events
+- **Modules**: separate parts that can use core features using engine public API
+
+## Requirements
+
+- **Make**: 4.4.1
+- **CMake**: 4.2.3
+- **GCC**: 15.2.0
+- **sqlite3-dev** (lib): 3.46.1
+
+## How to run
+
+1. Clone repository
+2. Run `sudo ./utils/install-oatpp.sh`
+3. Build: `cmake -B build` and then `cmake --build build`
+4. Run: `./build/magic_scrolls
