-On linux e.g. you would issue the following commands:
-
-```
-	git clone https://github.com/PDB-REDO/libcifpp.git
-	cd libcifpp
-	cmake -S . -B build -DCMAKE_INSTALL_PREFIX=$HOME/path/to/libcifpp/ -DCMAKE_BUILD_TYPE=Release
-	cmake --build build
-	cmake --install build

-This checks out the source code from github, creates a new directory
-where cmake stores its files. Run a configure, build the code and run
-tests. And then it installs the library and auxiliary files.
 
 
-The default is to install everything in `$HOME/.local` on Linux and
-`%LOCALAPPDATA%` on Windows (the AppData/Local folder in your home directory).
-You can change this by specifying the prefix with the
-[CMAKE_INSTALL_PREFIX](https://cmake.org/cmake/help/v3.21/variable/CMAKE_INSTALL_PREFIX.html)
-variable.
