 If homebrew for some reason could not install the necessary packages: ```lua luajit openal-soft```, then download, install and compile them manually (Lua, LuaJIT and OpenAL).

+## Build using Docker
+
+### Step 0. Install docker on your system
+
+See https://docs.docker.com/engine/install
+
+### Step 1. Build docker container
+
+```
+docker build -t voxel-engine .
+```
+
+### Step 2. Build project using the docker container
+
+```
+docker run --rm -it -v$(pwd):/project voxel-engine bash -c "cmake -DCMAKE_BUILD_TYPE=Release -Bbuild && cmake --build build"
+```
+
+### Step 3. Run project using the docker container
+
+```
+docker run --rm -it -v$(pwd):/project -v/tmp/.X11-unix:/tmp/.X11-unix -v${XAUTHORITY}:/home/user/.Xauthority:ro -eDISPLAY --network=host voxel-engine ./build/VoxelEngine
