-### Build with make
-
-Alternatively, you can build using provided Makefiles:
-
-```sh
-make -f Makefile.manual
-```
-
-You can limit the maximum rank by setting ``-DMAXRANK=<num>`` in the ``ADD_FYPPFLAGS`` environment variable (which can reduce the compilation time):
-
-```sh
-make -f Makefile.manual ADD_FYPPFLAGS=-DMAXRANK=4
-```
-
-You can also specify the compiler and compiler-flags by setting the ``FC`` and ``FFLAGS`` environmental variables. Among other things, this facilitates use of compiler optimizations that are not specified in the Makefile.manual defaults.
-```sh
-make -f Makefile.manual ADD_FYPPFLAGS=-DMAXRANK=4 FC=gfortran FFLAGS="-O3"
-```
-
-On some systems, ``make`` selects the wrong default compiler. If you encounter error messages like ``make[1]: f77: No such file or directory`` set ``FC`` to your preferred compiler (e.g., ``gfortran``) or try
-
-```sh
-make -f Makefile.manual --no-builtin-variables

 Documentation is a work in progress (see issue [#4](https://github.com/fortran-lang/stdlib/issues/4)) but already available at [stdlib.fortran-lang.org](https://stdlib.fortran-lang.org).

-New subdirectories have to be explicitly added to ``src/tests/Makefile.manual``
