+ABACUS current supports Linux. To compile ABACUS, please make sure that the following prerequisites are
 present:
 
-- C++ compiler, supporting C++11. For example, [Intel C++ compiler](https://software.intel.com/enus/c-compilers) or [GCC](https://gcc.gnu.org/);
-- Fortran compiler;
-- MPI compiler. The recommended version are [Intel MPI](https://software.intel.com/enus/mpi-library) or [MPICH](https://www.mpich.org/);
-- The ScaLAPACK library. For example, [Intel MKL](https://software.intel.com/en-us/mkl)
-or [Netlib ScaLAPACK](http://www.netlib.org/scalapack/);
-- The [FFTW library](http://www.fftw.org/). ABACUS now supports both FFTW2 and
-FFTW3;
-- The [ELPA library](https://elpa.mpcdf.mpg.de/);
-- The [CEREAL library](https://uscilab.github.io/cereal/);

+- MPI compiler. The recommended version are [Intel MPI](https://software.intel.com/enus/mpi-library) or [MPICH](https://www.mpich.org/).
+- Fortran compiler for building `BLAS`, `LAPACK` and `ScaLAPACK`. You can use[Intel® Fortran Compiler](https://www.intel.com/content/www/us/en/developer/tools/oneapi/fortran-compiler.html) [GFortran](https://gcc.gnu.org/fortran/).

-Alternatively, you can choose [Intel® oneAPI toolkit](https://software.intel.com/content/www/us/en/develop/tools/oneapi/commercial-base-hpc.html) (former Parallel Studio) as toolchain. The [Intel® oneAPI Base Toolkit](https://software.intel.com/content/www/us/en/develop/tools/oneapi/all-toolkits.html#base-kit) contains Intel® oneAPI Math Kernel Library (aka `MKL`), replacing `FFTW3, LAPACK,` and `ScaLAPACK`. The [Intel® oneAPI HPC Toolkit](https://software.intel.com/content/www/us/en/develop/tools/oneapi/all-toolkits.html#hpc-kit) contains Intel® MPI Library, and C++ compiler(including MPI compiler). Please noted that building `elpa` with a different MPI library may cause conflict between MPI libraries.

-If you use Intel toolchain, don't forget to [set environment variables](https://software.intel.com/content/www/us/en/develop/documentation/get-started-with-intel-oneapi-render-linux/top/configure-your-system.html) before you start! `cmake` will use Intel MKL if the environment variable `MKLROOT` is set.
