 A game engine or something, idk.
 
 ## Installation
-1. Clone the repository.
+1. **Clone the repository.**
 ```sh
 git clone --recurse-submodules https://timerix.ddns.net/git/Timerix/ougge.git
 ```
-2. Install [cbuild](https://timerix.ddns.net/git/Timerix/cbuild).
-3. Install [SDL2](https://github.com/libsdl-org/SDL) and [SDL2_image](https://github.com/libsdl-org/SDL_image).
+2. **Install [cbuild](https://timerix.ddns.net/git/Timerix/cbuild).**
+3. **Install [SDL2](https://github.com/libsdl-org/SDL) and [SDL2_image](https://github.com/libsdl-org/SDL_image).**
     - On **Linux** install shared libraries from a package manager or compile them from source.
     - On **Windows** download pre-built dll's from github releases and put them into `dependencies/precompiled/`.
-4. Symlink SDL headers directory to `dependencies/include`.
+4. **Symlink SDL headers directory** to `dependencies/include`.
     ```sh
     ln -s SDL2_HEADERS_DIRECTORY_ABSOLUTE_PATH -T dependencies/include/SDL2
     ```
     Location of the headers can be found by `pkg-config --cflags --libs sdl2`. 
     Mingw installs SDL2 headers to `/mingw64/include/SDL2`. 
-5. Install [mono](https://github.com/mono/mono).
-    
-    **Windows:**
-    1. Install mono from official website
-    2. Copy `*.dll` files from `C:\Program Files\Mono\bin` to `dependencies/precompiled/`  
-    3. Copy `config` from `C:\Program Files\Mono\etc\mono` to `dependencies/precompiled/mono-libs` and rename to `config.xml`
-    4. Copy `mscorlib.dll` from `C:\Program Files\Mono\lib\mono\4.5\` to `dependencies/precompiled/mono-libs`
-
-    **Linux:**
-    1. Download and extract [sources](https://download.mono-project.com/sources/mono/index.html)
+5. **Download mono runtime** ([source is here](https://github.com/dotnet/runtime/tree/main/src/mono)).
+    - default version
         ```sh
-        mkdir mono
-        cd mono
-        wget https://download.mono-project.com/sources/mono/mono-6.12.0.199.tar.xz
-        tar xJf mono-6.12.0.199.tar.xz
-        mv mono-6.12.0.199/* ./
-        rm -r mono-6.12.0.199
-        rm mono-6.12.0.199.tar.xz
+        cbuild download_mono_from_nuget
         ```
-    2. Install `libz autoconf automake libtool gettext cmake python3 curl` and 
-    3. Build mono. If something doesn't work, read [documentation](https://www.mono-project.com/docs/compiling-mono/)
+    - or some specific version
         ```sh
-        mkdir -p mono_prefix
-        ./autogen.sh --prefix=$(realpath mono_prefix) --disable-boehm
-        make get-monolite-latest
-        make -j8
-        make install
+        cbuild download_mono_from_nuget=x.y.z
         ```
-    3. Install `patchelf`
-    4. Install mono files in project.
-        ```sh
-        cd ..
-        cbuild get_mono_files_from=mono/mono_prefix
-        ```
-    5. Now you can delete `mono` directory and save 3 gigabytes of disk space :3
-7. Compile the program
+7. **Compile the program**
     ```sh
     cbuild build_exec_dbg
     ```
