 To compile locally, on macOS, create a conda environment having the needed dependencies:
 
-    conda create -n polyview_dev qt=5.9.7 clang llvm-openmp
+    conda create -n polyview_dev qt=5.9.7 compilers llvm-openmp

-On Linux, replace ``clang`` and ``clang-cpp`` with the gcc and g++ compilers, which
-may be called, for example, ``x86_64-conda_cos6-linux-gnu-gcc`` and ``x86_64-conda_cos6-linux-gnu-g++``.
+    make install INSTALL_ROOT=$(pwd)
 
+This should create the ``polyview`` program in the ``bin`` subdirectory.
