 ### Windows
 
+Note that the static libraries distributed for Windows include several
+variants: mt, md, mtd, mdd. These correspond to the [run-time library
+flags](https://docs.microsoft.com/en-us/cpp/build/reference/md-mt-ld-use-run-time-library?view=vs-2017)
+`/MT`, `/MD`, `/MTd`, and `/MDd`, respectively. Here we use the mt variant.
+
+When building Filament from source, the `USE_STATIC_CRT` CMake option can be
+used to change the run-time library version.
