+Potential installation pitfalls:
+- The above will install the python package of the dependence GalSim. However, you may need to install the C++ shared library of GalSim, not installed by default with the above installation. Find details on how to do this [here][https://galsim-developers.github.io/GalSim/_build/html/install_pip.html]. You may then need to update your LD\_LIBRARY\_PATH, LIBRARY\_PATH, and CPLUS\_INCLUDE\_PATH to point to build and include folders for the GalSim C++ shared library.
