 ## Compiling the model and creating a project
 The only prerequisite to install LAKE model is Fortran compiler.
 The model can be built from source code by GNU and Intel Fortran compilers. GNU compiler is set by default in the model install configuration. Install configuration is given in files [Makefile](/../blob/master/Makefile) and [source/Makefile](/../blob/master/source/Makefile).
