 **Building with Docker**
 
 These examples assume that your current directory is the mtasa-blue checkout directory. You should also know that `/build` is the code directory required by our Docker images inside the container. If the current directory is not a valid git repository, it instead create a (shallow) clone of the mtasa-blue repository. After compiling, you will find the resulting binaries in `./Bin`. To build the unoptimised debug build, add `-e BUILD_CONFIG=debug` to the docker run arguments.
