+## Quick Build
+SPERR requires 1) a working C++ compiler and 2) CMake tools to build. On a Unix-like system,
+the build steps are the following:
+
+```bash
+git clone https://github.com/NCAR/SPERR.git     # clone the repo
+mkdir SPERR/build                               # create the build directory
+cd SPERR/build                                  # enter the build directory
+cmake ..                                        # use cmake to configure the project
+cmake -DUSE_OMP=ON ..                           # Optional: enable OpenMP on 3D volumes.
+cmake -DCMAKE_INSTALL_PREFIX=/my/install/dir .. # Optional: specify a directory to install SPERR. The default is /usr/local .
+cmake -DCMAKE_CXX_STANDARD=17 ..                # Optional: use C++17 rather than C++20. The code is slightly faster with C++20.
+make -j 8                                       # build the project
+ctest .                                         # run unit tests, which should have 100% tests passed
+make install                                    # install the library and CLI tools to a specified directory.
