 APFEL is a library able to perform DGLAP evolution up to NNLO in QCD
 and to NLO in QED, both with pole and MSbar masses. The coupled DGLAP
 QCD+QED evolution equations are solved in x-space by means of higher

-## Installation 
-### Dependencies
- - Fortran and C++ compillers.
- - (Optional) `make` for installation with `autotools`
- - (Optional) `CMake` (https://cmake.org/) > 3.16 for installation with `CMake` and any build system -- `make`, `ninja`, etc.
- - (Optional) `LHAPDF` library, for support PDFs in of Les Hauches format.
- - (Optional) `CPython` headers and `SWIG`, for compilation of Python bindings.
- - (Optional) Internet connection if the installation of PDFs was requested.
-
-### Compilation with autotools
-Checkout the code and compile the code using the
-following procedure:
-
-```Shell
-cd apfel
-./configure --prefix=/where/install/apfel #(optional)
-make && make install
-```
+## Installation
 
-By the default, if prefix is not set, the program is installed in
-/usr/local. If you define a different prefix, remember to export
-it into the `LD_LIBRARY_PATH` or `DYLD_LIBRARY_PATH`.
