+
+== How to build SLEEF
+
+The library itself does not have any additional dependency.
+
+In order to build SLEEF, you need CMake 3.18+, and C and C++ compilers of the same version.
+It is also recommended to have the following tools.
+
+* Ninja
+* Git
+
+https://github.com/shibatch/tlfloat[TLFloat] is automatically downloaded if no suitable version is found on your system.
+
+Some tests require:
+
+* libssl and libcrypto, that can be provided by installing openssl.
+* libm, libgmp and libmpfr
+* libfftw.
+
+
+The build procedure is as follows.
+
+[arabic]
+. Check out the source code from our GitHub repository
+
+....
+git clone https://github.com/shibatch/sleef
+....
+
+[arabic, start=2]
+. Make a separate directory to create an out-of-source build
+
+....
+cd sleef && mkdir build
+....
+
+[arabic, start=3]
+. Run cmake to configure the project
+
+....
+cmake -S . -B build
+....
+
+By default this will generate shared libraries. In order to generate
+static libraries, pass option `-DBUILD_SHARED_LIBS=OFF`.
+
+For more verbose output add option `-DSLEEF_SHOW_CONFIG=ON`.
+
+[arabic, start=4]
+. Run make to build the project
+
+....
+cmake --build build -j --clean-first
+....
+
+[arabic, start=5]
+. Run tests using ctests
+
+....
+ctest --test-dir build -j
+....
+
+For more detailed build instructions please refer to the
+link:./docs/1-user-guide/build-with-cmake[dedicated section on CMake] or
+to https://sleef.org/1-user-guide/#preliminaries[our web page].
+
+== How to cross-compile SLEEF
+
+For more detailed please refer to
+link:./docs/1-user-guide#cross_linux[cross-compile SLEEF]
+
+== Install SLEEF
+
+=== From source
+
+Assuming following instructions were followed.
+
+[arabic, start=6]
+. Install to specified directory `<prefix>`
+
+....
+cmake --install build --prefix=<prefix>
+....
+
+=== Uninstall
+
+In order to uninstall SLEEF library and headers run
+
+....
+sudo xargs rm -v < build/install_manifest.txt
